Kershaw Emerson Collaboration Review

For 2014 KAI USA and Emerson Knives have teamed up to deliver the first high volume, overseas produced Emerson designed ‘CQC’ knives. The release targets a thirsty market of consumers looking for the designer’s distinct ‘tactical’ aesthetic coupled with the wave opening feature at an affordable price point.

The CQC in the name stands for Close Quarter Combat suggesting a professional application amongst LEOs, Military Personnel, First Responders etc. They are also commonly sold as a self defence products. Regardless of the implied market I think that these will be popular with the EDC crowd and collectors who are fans of the category.

A total of eight 2014 models fall under the Kershaw brand. There will also be two knives positioned in the higher end market, the 0620 and 0620CF. These premium versions have their own designs and will be released with Zero Tolerance which is also a KAI property. The topic of this review will be the Kershaw models : CQC 1K through to the CQC 8K. They are roughly designated their model number (1-8) by overall dimensions (length, width, weight) and cost. They can also be visually differentiated by lock type, handle construction, blade style and finishes.

General Dimensions and Blade Details

The 1K, 2K and 3K models are quite small and range from 6.35” in overall length to 7.45”. The 4K and 5K’s are slightly larger in over-all dimensions and weight, but not quite as large as the designer’s standard line. The 6K, 7K and 8K will probably be the models that people will find the most like Emerson’s typical offerings. These are near to the size of the Mini-Commander or CQC 7’s, ranging from 7.75” to 8.1”. The Roadhouse that is being used as a comparison is an inch bigger than the largest Kershaw coming in at 9.1” in Overall Length.

All of the blades are made from the steel 8Cr13Mov. This is a stainless that has both reasonable edge retention and corrosion resistance for the price point. If you are looking for added corrosion resistance the black oxide models would be a better choice than the stone-washed editions. That said, I much prefer the aesthetics and well wearing surface of a stone-washed blade. The stone-wash covers the entire surface (not just the flats) and is a little less defined than a US made Emerson but it still looks good.

Patterns range from three tantos (CQC-3K, CQC-7K and CQC-8K) to four modified clip points (CQC-1K, CQC-2K, CQC-5K and CQC-6K) to one drop point (CQC-4K).

A flat grind produces a durable yet keen edge. Each has a standard V grind and edge bevel with the exception of the 8K where a chisel grind has been utilized. While all eight knives come sharp, the thicker stock favors strength over delicate slicing, typical of this genre. To make another comparison, Emerson uses a .125” (3.14mm) blade stock. The Kershaws are slightly thinner at 0.113” (2.9 mm). A model number and the manufacturer logo is etched on one side of the blade and a modified Emerson logo and skull appear on the other. Skulls aren’t for everyone but it’s pretty small. If you’re into skulls, you’ll be happy to know there’s one on the clip too.

Handle and Ergonomics

The handles are a partially closed back construction that uses an injection molded back-spacer. Since some models are liner locks and others frame-locks, finishes vary. All models have a grip thickness of .4 to .5” making them feel stout in hand and present in pocket. The CQC 4K and 5K are the only two with colored scales, all the rest have black G10 with black-coated frame or liner locks. The stone washed editions have bead blasted 410 stainless frame locks. The CQC 8 scales have some milled in surface detailing.

The G10 texture is less aggressive than the standard Emerson peel-ply stock. Some people may criticize this and others will appreciate the lack of pocket wear. I fall into the latter. The stainless frame-lock editions don’t have any texture so there will be little to no pocket wear. Addressing the pocket clips, it’s important to note that they are all tip up and unlike stock Emerson’s, reversible for ambidextrous carry. Retention is great and works well with the wave.

The ergonomics are varied throughout the line. The smaller editions feel a bit small in my hands with their 3 finger grip. The 1K and 3K’s straighter handles feels more comfortable since there’s less of a curve on the inner edge toward the pommel. All of the models above the 3K feel great to me with the exception of the 8K which has some pretty specific lines. That’s not to say it won’t fit like a glove for some, but I would suggest holding it in person first if possible.

Once again I feel that the 6K and 7K’s hit a sweet spot. The deep finger groove adds excellent retention and the rest of the handle’s contouring nests comfortably in hand. The jimping on all models is fairly smooth yet still provides some feedback and traction in use. On all the models, the wave also doubles as a thumb ramp for finer control.

Deployment and Lockup

For deployment all models have both a knurled thumb-disc and the patented “Wave”. The Waves are, as far as I can tell, all the same size. Being familiar with the technique, I haven’t had a problem repeatedly and reliably opening the knives this way.

While most people who read this site know what the wave is, I’ll dial it back and briefly explain. The wave opening feature consists of a protrusion on the blade’s spine. When drawing the knife from a closed and clipped-on position, it catches on the rear seam of your pocket. With a quick up and backward movement the blade opens without additional manipulation. Because it all happens at the same time you produce the knife, it’s the fastest way to open a folder. This has made the wave a popular option on back-up or self defense knives as it combines easy carry with very fast deployment.

On the down side ‘waving’ a knife will undoubtedly be seen as an aggressive act if you’re doing it at the office. You’ll probably want to use the thumb-disc which allows you to deploy your CQC without the attention in those situations.

When open both liner and frame locks are solid and without play. Lock-up contacts close to, or at 100% of the lock face. I think that this is a good move. When opening with the wave is important to have a full and audible engagement for safety.

The fasteners used for construction are standard flat heads for the pivot and Phillips heads for the rest. This is great for easy adjustment when necessary. Any standard multi-tool or typical at hand screwdrivers will do.

Over-all the fit and finish of the knives is quite good. Some may be surprised that there are some areas where the Kershaw models are more resolved than their higher end counterparts. On the originals there is often rough tooling around the perimeter of the handles, liners and blade edges. The Kershaw models are quite clean. Blade centering on all eight of the knives received for review was spot on. Below are a couple of details that show differences in the fit and finish.

Kershaw Emerson Collaboration Review – Final Thoughts

All in, Kershaw did an excellent job bringing these designs to market. With all of the differences in sizes, shapes and finishes there should be something here for everyone. Releasing eight new models from one designer is a pretty bold statement but one that will likely be backed by excellent sales.

Personally I like the 4K through to the 7K, their ergonomics felt the most comfortable. The 6K and 7K stone-wash looks the slickest in my opinion. Personal taste aside, these are 30 to 40 dollar knives. About a quarter to a fifth of the price of a US made Emerson.

Hinderer Knives XM-18 Slippy Review

by Dan Jackson 9 Comments

Hinderer Knives is a company best known for their overbuilt XM Series. Burly titanium framelock flippers that helped popularize the titanium framelock flipper. So to see them release the XM-18 Slippy, a slip joint using their XM pattern, is a bit of an oddity. But then again, it’s not that surprising given the recent resurgence of interest in slip joint knives.

Buy the Hinderer XM-18 Slippy at BladeHQ

And oddly enough this may be their most practical daily carry folder yet. Reasonably small, slim, lightweight, and retailing for under $300, this may be the Hinderer that you didn’t realize you needed.

General Dimensions and Blade Details

The XM Slippy has an overall length of 7″, a 3″ blade, weighs 3.71 ounces, and is made in the USA. It’s a great size for urban or suburban daily carry. It has similar dimension to the XM-18 3″, but is a hair thinner, .4 ounces heavier, and $150 cheaper.

I think if they had to borrow from one of the XM framelocks, the 3″ version was smart. This is all I need for an EDC knife. The 3.5″ version would have been way too much.

Hinderer has rolled this knife out in a couple of blade shapes, but shown here we have their classic drop point. It’s hard to go wrong with the clean look and practical features of a drop point. A good functional tip, plenty of belly, and Hinderer’s high flat “slicer” grind all work together to provide all-round performance.

Most of these early XM-18 Slippys appear to be coming with CPM-20CV blade steel. We are starting to see more high end knives in CPM-20CV. I’ve reviewed a couple Benchmade knives in this steel, including the G-10 Griptilian. Another notable knife in CPM-20CV is the Cold Steel 4MAX.

So at this point I have a few knives in my long term collection in CPM-20CV and I’ve put some miles on them. CPM-20CV is Crucible’s answer to Boeller M390. It’s the same chemical composition as M390, but it’s made by Crucible in the USA. I think it’s a great steel, and it provides a good blend of edge retention, ease of sharpness, corrosion resistance and toughness. Here is a link to ZKnives’ page on 20CV where you can get some more details.

In practice this is a slicey knife that has performed admirably in all the typical EDC chores. I have used my Slippy for your basic EDC knife stuff including opening mail, breaking down boxes, light food prep, and the random jobs that you invariably encounter when carrying a pocket knife. For each task the Slippy worked fine. It slices well and the stonewashed finish hasn’t shown much in the way of wear. Edge retention has been great, and when it’s time to touch it up, all I’ve needed to do is run the edge along the fine stones that came with my Spyderco Sharpmaker. I can’t ask for much more out of a daily carry blade.

Handle, Ergonomics and Pocekt Clip

The handle is textured G10 scales over titanium liners secured with Hinderer’s custom hardware. One complaint is they have a lot of extra bolts on this thing. The show side has the pivot, 2 bolts by the lanyard hole, and then 3 button head bolts running across the handle. These may be necessary for their slip joint mechanism, but it’s not pretty. It would look much cleaner if they could ditch the button heads.

Beyond that, everything has been executed with Hinderer’s typical care and attention to detail. All the pieces have been beautifully finished, the parts line up, and any sharp edges have been broken. Anyone who has handled a regular XM will know what I’m talking about. The fit and finish is top notch.

This is a comfy little knife. The 3″ XM pattern is tried and true, and it’s just the same for this slip joint version. You have a good size handle with plenty of room for a full 4 finger grip. If you want to choke up on the blade you can with the forward choil. There is a run of mild jimping on the spine of the handle right above the pivot, and the textured G-10 scales offer grip without shredding your pocket like a fresh emery board.

The pocket clip is your standard XM-18 spoon style clip positionable for right side tip up or tip down carry. This is a proven clip that does a good job of keeping the knife mostly buried in the pocket. Hinderer includes a filler plate so you fill the void in the G-10 when you reposition the clip.

There isn’t much to complain about when it comes to this pocket clip. Some may favor a deep carry clip, but very little of the handle peeks up out of your pocket anyway. In practice the Slippy carried like a dream. Thin, lightweight, and discreet.

Walk and Talk

For the most part, all the stuff above is essentially a review of the 3″ XM-18 in CPM-20CV steel. Nothing earth shattering in my findings. This section is where it gets interesting. Our titanium framelock has been replaced with a slip joint, and our flipper and thumb studs have been replaced with an adjustable thumb disk.

The thumb disk is removable with an allen wrench, so this knife can be made into a 2 hand opener. Good for certain legal jurisdictions. Personally, I left the thumb disk on, but I did adjust it by loosening it with an allen bit from my WiHa bit set, and then sliding the thumb disk down the channel cut into the blade.

I positioned it to a good “sweet spot” where my thumb naturally brushes it when gripping the knife. In practice I think this is a cool feature. The groove in the blade may look a little weird at first, but I quickly got over it, and I like how the thumb disk can be adjusted to fit your hand.

Here is a size comparison with the Slippy next to my Spyderco Native 5:

Lets talk about the walk and talk, since this is a slip joint after all. The backspring on this knife is pretty good. I’d give it a “6” on a 1-10 scale, with 1 being floppy, and a 10 requiring significant force. I’d put most Swiss Army Knives around a 3 or 4. The Slippy has a good amount of resistance, but it won’t rip your fingernails off as you try to open the blade.

The blade opens up with a satisfying snap, and that same strong spring holds the blade open. There isn’t a hard half stop, but there is a “no man’s land” at the 90 degree point. From there you can push the blade closed and the spring takes up the slack to bring the blade home.

Blade centering is perfect on my knife.

Hinderer Knives XM-18 Slippy Review – Final Thoughts

I liked this XM-18 Slippy more than I expected to. What I appreciate is the simplicity. The Slippy has everything you need, and nothing you don’t. I know everyone’s needs are different, but for me 99% of the time I don’t need a locking folder for my daily carry chores. So this slip joint version strikes me as streamlined and practical given what I require out of an EDC knife. For those wanting a more robust locking folder, there is always their regular XM-18 series.

In addition to the practicality of the XM-18 Slippy, I’m also drawn to the price. A sub $300 Hinderer is an accomplishment in my book. The Slippy is a full $150 cheaper than their framelock version. It’s still expensive, but this is a relatively small batch precision product made in the USA. It oozes the kind of quality you would expect from Hinderer. My example is flawless, and at this price I’m a little more inclined to roll the Slippy in my daily rotation carry than keep it as a collectible.

As for potential downsides, I’m not a fan of the extra screws featured on the show side. I haven’t taken this knife apart to see why the bolts are necessary, but probably should. If I do I’ll snap a picture and update the review. Also, some may not be able to get around the thumb disk and channel in the blade. It’s unusual and strikes me as an acquired taste, but I don’t mind it. Like the rest of the knife, it’s practical and it works.

In closing I think Hinderer did a nice job with their take on the slip joint. The slip joint bandwagon has been gaining a lot of steam lately, but Rick and his team have found away to offer a unique take on the slip joint that compliments their existing lineup. Recommended if you are looking for a premium non-locking EDC, are curious about the design, or are a fan of Hinderer knives in general.

Custom Knife Factory Decepticon 2 Review

by Andrew Gene Leave a Comment

Ever since the explosion of the Shirogorov brother’s knives, there has been an increased interest in what is being produced in Russia. This has been pushed further along by a growing amount of breakout designers, most notably Dmitry Sinkevich. Sinkevich, a long time Shirogorov collaborator, has also worked extensively with KAI USA. The outcome was a high end knife in the Limited Edition 0454, mid range knives in the 0452CF and 0450 as well as budget conscious models like the Kershaw Nura.

Buy the CFK Decepticon 2 at BladeHQ

The KAI collaboration has resulted in wider exposure and greater accessibility to Russian designs outside of Shirogorov, who were previously the go to brand. The issue with enjoying a Shirogorov has always been the initial price point and/or inflated after market cost, partly due to available knives and a near monopoly on their distribution in North America. While somewhat inaccessible, the popularity of Shirogorov has opened up a wider market for other Russian designers and manufacturers. At the same time, the KAI collaboration put similar designs into more peoples hands.

Enter Custom Knife Factory. Custom Knife Factory is a relatively young manufacturer headed by Mikhail “Mike” Kulygin. The aim of the brand is to work with some of the “newer” talent on the Russian Knife scene. I quote ‘newer’ as some of these designer/makers have been around for quite some time. It’s just that they are only coming into our popular North American knife culture as of late. One such designer is Alexey Konygin the creative mind and craftsman behind the knife in this review. I personally have been very interested in Alexey’s designs after seeing a video of a custom Decepticon “1” on YouTube in 2012. Impressively 2011 is when the designer came onto the scene, hitting the ground running with his original offerings. Three years and a new iteration later, I’m very happy to present a review of the Konygin/CKF Decepticon 2.

General Dimensions and Blade Details

The Decepticon 2 is a large folder, produced in a limited run of 300 natural-finish titanium handle versions. The over all dimensions are 9.69” with a substantial 4.33” blade and weight of 6.06 oz. It’s difficult to perceive the size of the knife based on the numbers alone, it’s best to hold one to get the idea. The designer has stated a liking for big knives and this certainly fits the bill. Despite its size, it actually feels quite light in hand due to the handle’s structure.

The blade is made from Crucible’s S35VN, a widely used powder metal “super steel”. It is considered an upgrade to S30V through the addition of Niobium and has pretty much taken its predecessors place in mid to high end folders. Overall, this stainless has great edge retention and toughness, yet is still fairly easy to maintain.

The profile is a stylish modified drop point. A high flat grind adequately reduces the .156” stock at which point it receives a secondary edge bevel. The spine has a slight concave curve for thumb placement which changes direction mid-spine, arcing downward to meet the belly at a fine tip. The upper portion of the blade is detailed with a stylized thumb hole that is accented by a deep swedge grind and line milled into the upper corner of the opening. Visually, the line here continues up to a small thumb ramp that has a row of fine jimping. The blade has a light stone wash finish and is kept clean of markings except for text indicating the steel type. To help with sharpening, there is a good sized choil allowing you to work the edge right to the heel.

Handle, Ergonomics, and Pocket Clip

The handle is constructed of sculpted slabs that stack together integrating to define the Decepticon’s distinct aesthetic. The two inner parts of the frame include all of the key mechanical components, like the lock and a channel for the stop pin. The outer scales add more width for a full feeling grip while their cutouts create counterpoints with the inner, latticed frame. At each end, the layers shear off at contrasting angles adding another interesting aspect to the multi-faceted design. Although the shapes appear to have several hard angles, the overall profile, coupled with some nice chamfering makes for a surprisingly comfortable grip. The only exception to this for me, is the end of the clip which can feel sharp if you hit it the wrong way.

While on the topic of the clip, it works well with a good amount of tension. It blends into the rest of the design and has been nicely machined. As another feature, the partial back-spacer raises away from the frame creating a spot for a lanyard. The back-spacer is marked with the knife’s unique serial number, this one being #67 of 300. The CKF logo also appears etched on one of the exposed surfaces of the liner.

Deployment and Lockup

While there is the thumb hole, the Decepticon 2’s main deployment method is its flipper. As with most details of the knife it is also embellished with a cutout. Functionally it works well, snapping the substantial blade into place with a push or pull, equally well.

The lock up is very solid with good tension allowing it to seat and disengage easily. The end of the lock arm has a steel insert with a similar configuration to Zero Tolerance’s knives in that the part also includes the detent. To help comfortably unlock the knife and to provide easier access to the lock arm, the inside of the scales are chamfered. The mechanism travels on thrust bearings for smoothness and lateral stability. Everything is held in place by an over-sized custom pivot.

Custom Knife Factory Decepticon 2 Review – Final Thoughts

Although individual taste will vary, it is undeniable that the Decepticon designs are unique. If looking at it objectively, all of the key functional components are there. The blade is useful, handle comfortable, lock strong and materials premium. More impressively the design does this while visually setting itself apart from anything else currently out there.

I think that the name might be a little confusing when approaching this design because of it’s association to the movie franchise. Michael Bay might narrow the market appeal. As a note, Konygin named the knife after designing it and has stated that it was not inspired by the movies…

Personally I really enjoy this iteration and production of the Decepticon. It has achieved a delicate balance of generous embellishment without looking gaudy or ostentatious. I would equate this to the approach of creating shapes and lines by removing stock, instead of piling on extra details, like moku-ti or engraving. It clearly shows off a creative, innovative liner lock assembly with an intelligent utilization of modern methods and materials.

I especially appreciate how well thought out the lines and shapes are on this design. Alexey Konygin has paid great attention to the interaction of all the elements when the knife is both open and closed. From a manufacturing perspective the knife is very well made with a top end fit and finish. I’m looking forward to seeing more CKF collaborations and Konygin designs in the future. I’m sure that these collaborations will help quench the healthy thirst for more Russian designs.

Demko Knives AD-15 MG Review

by Aaron Shapiro 5 Comments

There are knives that elicit feelings of elegance and delicate class, and then there are knives that make you feel like you’re carrying a tool that can handle damn near any task that you throw at it. Demko Knives belong solidly in the latter camp.

Buy the Demko Knives AD-15 at BladeHQ

For those of you that are hearing the name Demko and it’s sounding familiar Andrew Demko is the designer of Cold Steel’s famed Tri-ad Lock as well as some of their (in my opinion) coolest designs. Demko has also maintained his own custom knife shop, producing well built heavy-use folders that kept that distinct look that made his name famous among knife aficionados.

Based on my experience knives from Demko’s shop directly were a little difficult to come by when I first started getting into custom pieces. I’m not sure if that due to his work with Cold Steel, or maybe just the circles I ran in… but recently Andrew did two things that changed this. First he developed a new lock, the scorpion lock, that is not available from Cold Steel and secondly, he developed his Machine Ground (MG) series.

I would probably call his MG series mid-techs, although from what I have heard the only difference between Demko customs and the MG’s is the actual grinding of the blades themselves. Obviously his customs are hand ground, while the MGs are machine ground. More on that later.

First, the ever important specs of our Demko Knives AD-15 MG, the subject of this review:

Blade Length: 3.75”
Overall Length: 8.625”
Handle Thickness: .59”
Blade Thickness: .196”
Steel: S35VN
Weight: 6.4oz
Lock: Demko Scorpion Lock
Country of Origin: USA

(Please note these measurements are according to my ruler and calipers. The manufacturer’s listed measurements may vary.)

Blade Details

So, as I stated in the intro these knives are part of the “MG” series that the Demko shop is now putting out. I think the overall idea is to get some of their knives into customer’s hands without having to have the custom price-tag attached. In order to cut down on the cost, they have opted to put Machine Ground blades in these AD-15s. Apart from that I think there are minimal cosmetic differences between these and the customs.

So what does this mean for the end user? Well, nothing really. The knife is evenly ground, with crisp lines and a thin flat grind, and it is finished extremely well. For the run that was available at Blade Show, where I bought this knife, they had actually gone back and put a machine-satin or grind-line finish on the blade. This is generally my preference in a blade finish.

All that said, the knife came to me horrifyingly sharp, and I say this as someone that can sharpen a knife to a mirror–hair whittling edge. The Demkos did something to make this knife glide through paper like nothing I’ve seen. What makes this even more remarkable is the blade is made from 4.5mm thick stock. That is thick stock for a folding knife.

The steel choice is worth noting as well. S35VN is a weird pick for a knife that I’d consider a “heavy-use knife.” Don’t get me wrong as S35VN is generally a fine steel. I have it in my Chris Reeve knives and it’s performed great for me, but I would have expected 3V or M4 in this monster. Gimme something with some real brawn, Demko!

I suppose the choice of S35VN isn’t really a problem, as S35VN is still a premium steel with a well deserved reputation for all-round performance. It was just a surprising choice to me as this knife is otherwise entirely overbuilt. I think a tougher steel with a greater reputation for hard use would have been even better under these circumstances.

Handle, Ergonomics, and Pocket Clip

To address the elephant in the room before we talk about anything else, the AD-15 MG is a big knife. I mean the thing is over eight and a half inches long. However, as a result Demko was able to figure out how to incorporate a very effective saber-style handle to the knife. This allows you to grab onto it and know that you’re not going to slip anywhere, and to add additional traction most of these knives are offered in textured G-10 or Micarta for even more grip.

As for the handle material itself, it’s okay. Don’t tell anyone I said this, but I kinda wish I had gotten a G-10 version. The natural micarta has a raw edge that has turned out to not really be my favorite. His G10 knives were very nicely squared away, I’d love to see one in CF.

The Demko’s are also now offering these knives in full Ti handles. This was debuted at Blade 2018. In my opinion full titanium is a lousy “upgrade” as it adds nearly $200 to the price tag and a lot of extra weight, but the full titanium version offers no additional operational strength.

The clip is a ho-hum spoon style three screw clip that straddles the lanyard hole. This placement makes the knife ride a bit high in the pocket. I love and hate this high clip placement. On one hand, it allows you to have a really positive grip on this (expensive) knife in your pocket when you withdraw it, but the knife is also is going to dig into your side when you sit down. So this clip configuration has its pros and cons.

Deployment and Lockup

Dudes, this lock is super weird. Like, I get it, and I like it, but it took me a solid 2-3 days of playing with it where I stopped nearly cutting myself when I tried opening it. The knife is not that different from the famed Tri-ad lock that Demko licensed to Cold Steel. It’s essentially a titanium bar that runs across the top of the knife, that bar pivots around a pin towards the rear, when doing so it lifts the locking pin and allows you to close the knife. That same spring tension also serves as the “detent.” As a result, you sorta have to push away from the pivot when you open the knife otherwise it won’t budge.

As I said, it’s a different but ultimately intuitive way of opening a knife. Another result of this lock is that the action of the knife has a very hydraulic feel to it. It’s smooth, but slow. As if you were pushing the blade open through soft butter. This isn’t a knife that you’re gonna “pop” open with your thumb. The AD-15 MG’s run on poly washers, so that contributes to the slow hydraulic feel of the action.

Demko Knives AD-15 MG Review – Final Thoughts

How do you pin a bow on a knife this unusual? It’s a new style of mid-tech, with a new locking system, in a different size category than I normally buy. I never condone knife abuse, but the AD-15 seriously feels like a knife that could do pretty much anything and go pretty much anywhere. Need to stab through a car hood? No problem. This AD-15 MG is an absolute tank, and in that capacity this knife is phenomenal.

With a different steel I think the AD-15 MG’s would be perfect. S35VN is fine for a Sebenza, but for an overbuilt folder like this I’d love to see the jump to an even tougher steel like 3V. I believe that Demko has used different steels on the hand ground versions, so perhaps that will trickle down to the MGs eventually.

Also, these knives aren’t cheap. The base model (with G10 or Micarta) comes in around $675 and is readily available on BladeHQ or even Amazon. This AD-15 MG is a lot of money, but you’re essentially getting a custom Demko that has a blade that went through a double disk grinder. Practically speaking it’s very similar to what they’d call a “custom knife.” The hand ground version of this knife starts at $900, and if that’s if you can find one.

For these reasons, I recommend the Demko Knives AD-15 MG if you want a hard use folder from Andrew Demko without spending the cash on one of his full customs.

Rockstead RYO Review

by Andrew Gene 2 Comments

The RYO is the latest folder from Rockstead, coming after their futuristic SHUN collaboration that was the work of Belorussian designer Dmitry Sinkevich. The SHUN was a tangent from the company’s previous aesthetic sensibilities, carrying much more futuristic lines in a larger form factor. Rockstead’s unmistakable mirrored blade grind and stylized fuller aside, the knife was definitely something more akin to other Sinkevich designs like the ZT 0452CF or his Shirogorov collaborations.

Buy Rockstead Knives at BladeHQ

The RYO design is a redirect back toward Rockstead’s other models, with a distinctly Japanese look that draws inspiration from an iconic friction folder. While most models reflect sword patterns, the RYO references the Higonokami (Higo for short) resulting in something similar to a modified wharncliffe, in Western cutlery terms. The blade shape is paired with an undulating handle texture reminiscent of waves, or in this case maybe black raku ceramics or “Japan Black” lacquerware. The name RYO translates to “good”. From my research it can be used to describe something of superior quality or character and is also used as a persons name.

As a side note, it might have been appropriate to call the RYO the HIGO however, Rockstead already has a knife named that. Although claiming the name, the model carries it in spirit only, and does not share a similarity in blade style.

General Dimensions and Blade Details

Although the Rockstead RYO has a foot in the past, it’s clearly a modern knife showing off a finished product that is only possible through a combination of modern machining and the latest high-tech materials. The over-all length measures 7.716” (196mm) with a 3.125″ (79mm) blade, and a weight of 4.37 oz (124 g).

New to the folding knife collection, the RYO has a “concealable” clip design. We are also seeing a titanium handle, rather than the Duraluminum that’s has been used in the past. This isn’t that surprising as most of the newer, all metal handles (as seen in the SAI and SHUN) are full Titanium.

The 3.15” (80 mm) blade is made from one of Hitachi Metal’s flagship cutlery steels, ZDP-189. ZDP-189 boasts rather extreme specifications with a chromium content at 20%, nearly double the 10.5% needed to consider it a stainless, and a carbon content of 3%, just over four times the 0.7% needed to be classified as “high carbon”. The full specifications are as follows:

Carbon	Chromium	Molybdenum	Tungsten	Vanadium
3.00	20.00	1.50	1.50	0.10

Such impressive specifications are reached through a powder metal technology which helps to avoid the uneven (segregated) carbide micro-structure caused by cooling steel into a traditional ingot. During the process, molten alloy is pushed through a nozzle where it meets a high pressure stream of air. At contact with the compressed air, the molten metal rapidly solidifies creating a tiny, near-to segregation free, sphere-like particle. Because the cooling is so fast, the component elements are fixed in place with a more even micro-structure. The powdered batch is then mixed and sealed into inert-environment containers to avoid unwanted reactions. Finally it’s Hot Isostatically Pressed (HIP), trapping all of the ideal properties, evenly into place.

With such generous levels of elements that make for a high-performance steel, ZDP-189 is able to reach an incredible finished hardness and take an equally impressive edge. Rockstead measures each piece and the small dimple left from measurement is proudly displayed on the blades ricasso. The hardness of this particular RYO measures 67 RC.

While seemingly the end goal for a steel, the result does compromise other desirable attributes. The first is accessibility. Using ZDP-189 and finishing it to these standards increases cost. Secondly, such a high hardness makes the steel more brittle since it lacks any real ductility, limiting application to lighter duties.

This steel is chosen to support the grind, and as on all other Rockstead knives, the grind is nothing short of amazing. Rockstead defines the convex, zero geometry as Hon-zukuri which is traditionally reserved to describe sword patterns. The meaning loosely translates to “base style” and is Rockstead’s go to configuration. On other models they also offer flat grinds that include a secondary bevel as seen on the TEI-S DLC.

I’ve had the opportunity to handle three Rockstead knives and the mirrored finish is perfectly executed on all, only showing distortion from the curvature of the convex shape or on the compound angles that radius the belly of the blades. Because the mirrored finish runs right to the edge, the cutting performance is outstanding with a sharpness that seems to pass effortlessly while in use. This is partly because the blades are pretty much perfectly symmetrical and there isn’t any tooth to the edge that can catch on the material you’re cutting. While pretty legendary for a knife; as mentioned before the edge is fragile and it will micro-chip under normal use. This is where questions of practicality comes into play. Your flawless blade can be maintained – if you use Rockstead’s paid sharpening service. Otherwise you can do the job yourself at the expense of the perfect finishing.

As for the profile, the Higonokami-like pattern is very useful. The slightly curved edge is excellent for everyday tasks while the tip excels at fine work over something like a drop-point. For detailing Rockstead’s stylized fuller gives the blade an animated, vigilant stare while the media blasted flats provide a contrast that intensifies the polished grind.

Handle, Ergonomics, and Pocket Clip

The fully sculpted “3D machined” handle of the knife is very comfortable. The inner edge has a series of shallow finger grooves that conform to your hand nicely. At 4.566” in length you get a full grip for average sized hands. The area of use is extended by a deep choil that meets a curve toward the front of the handle, allowing you to choke up for more control. Added grip and tactile feedback is helped along by jimping on the clip’s back and a double row of jimping along the handle’s spine that’s continued by a run onto the blade’s thumb pad. There’s also a small swatch on the choil so you know exactly where you’re at when your finger is near the heel of the edge. Jimping mission accomplished.

The cross cut ridges add a significant dress factor to the polished handle, catching the light and defining the overall form. As you hold the knife in your hand, highlights roll across the surface giving the grip a jewel-like appearance that’s amplified by the dark, glassy DLC (Diamond Like Carbon) coating. The same reflective qualities that give the handle its presence also create some challenges. With so many surfaces and such a tricky polish, any small marks or areas of unevenness during the process tend to be exaggerated by the DLC and under very close inspection, some are visible. This can only really be observed when the knife is spotlessly cleaned up and under good light as was the case when producing the video overview. Also, it’s an epic finger print magnet. From one perspective I’d like to see the handle as immaculately rendered as the blade and from the other I appreciate the ambition.

An area where I definitely feel the handle could be improved however, is weight. Milled out pockets on the inner scales could trim fat from the 4.37 oz. While this won’t bother some and others will equate weight with value, I prefer a lighter folder, and sub 4 oz would feel better with this smaller form factor.

For deployment there are two ambidextrous thumb-studs. While polished, they have a conical shape that narrows at the base, sit high and are exposed by a handle cut-out so you can easily and repeatably use them.

When opened the blade is held solidly by a button lock. Most button locks I’ve handled have a small tick of movement that eventually settles in, and this seems to be the case with the RYO. As of now, after handling the knife for some time, the lock-up feels totally solid and without play. Although seating confidently under significant spring tension, the action is smooth and without stickiness. When unlocking, the polished button head feels good under your thumb.

Normally, a button lock’s plunger serves double duty and is also used to hold the blade closed. In many cases the tension in the closed position is light allowing the blade to more easily fall out of the stowed position than something like a liner or frame lock. With the RYO, Rockstead has smartly added a separate detent that holds the blade closed, so the tension can be dialed in independently. As a small gripe, I’m not overly fond of the high pitch click the knife makes when overcoming the detent, but in a luxury item I tend to split hairs. Regardless of any criticism, the sum of parts of this button lock equals one the nicest I’ve handled to date.

Rounding out the details there is what Rockstead calls their “concealable” pocket clip. This is primarily an ergonomic feature so you don’t feel the clip when cutting. The integration is nicely executed and works visually when the knife is both open and closed. To reveal the clip, you manually push on its end which sits slightly proud when hidden. Although the small tab is visible, you don’t really feel it under normal use. The clip sits on a larger base that supports it, for a smooth yet robust feeling action. Because the clip is oriented to the back of the handle, its attachment point is best at your pocket seam (as opposed to along the opening) and works better with thinner fabrics. The fact that the clip is machined rather than stamped and bent, makes for a strong tension and, because of the orientation, the knife can twist to the side with thicker materials. I guess this isn’t really a jogging pants type of knife anyway.

Apparently this concealable clip design infringes on a patent filed by knife maker Joseph Caswell, who has a design called the EDX with a clip that automatically changes position with the action of opening and closing the blade. As such Rockstead has had to license in order to stay above board. As an additional carry option there is a lanyard hole that is discretely milled into the pommel.

Rockstead RYO Review – Final Thoughts

From the material choices through to the finished functional design, Rockstead personifies the ethic of Japanese bladesmithing. An approach where there is a thirst for the best technology and materials while still respectfully integrating knowledge and concepts from the past in balanced measure. Rockstead’s ability to harmoniously combine historic patterns with contemporary features is unique to the brand. While costly, these knives are truly distinct, no small feat in a market that is increasingly more saturated. The RYO is certainly “good”.

Kershaw Atmos Review

by Josh Wussow 2 Comments

Look – We all try to stick to a budget. But as knife enthusiasts, we sometimes have a bit more difficulty than most. This is one of the reasons I’ve gravitated toward the shallow end of the blade pool. So, when the Kershaw Atmos made a big splash with some fellow reviewers, I decided to see what all the fuss was about.

Buy the Kershaw Atmos at BladeHQ

General Dimensions and Blade Details

Let’s get the obvious comparison out of the way – Yes, the Atmos looks like a budget version of the Zero Tolerance 0450. And it should, considering they share a common designer in the great Dmitry Sinkevich. But, as you’ll see in the comparison photos, the Atmos is between 10 and 15-percent smaller in most of its physical dimensions. We’ll come back to this comparison later, but let’s focus on the Kershaw for now.

The centerpiece of the Atmos is its 3-inch drop-point blade, wearing a satin finish over its hollow grind and upper swedge. It’s been crafted from a 0.10-inch thick piece of Chinese 8Cr13MoV steel, which is sure to illicit groans from about 90-percent of the audience. Look – I don’t like this steel any more than you do. But, hang with me for a while, and maybe you’ll learn to look past it.

Overall, the Atmos measures 6.9-inches, nearly four of which make up the G-10 handle. There’s a stainless steel insert on the clip side, housing the linerlock mechanism. Kershaw has included attractive carbon-fiber overlays on each handle slab (read: stickers), which somehow manage to avoid looking tacky on this budget-minded blade. I’m not usually a huge carbon fiber fan, but the added layer brings the handle width to a pleasing 0.43-inches. Weight-wise, the Atmos tips the scales at just 2-ounces. For those of you keeping track, that’s within 0.1-ounces of the Kershaw Fraxion, despite housing a bigger blade and far superior design.

Handle, Ergonomics, and Pocket Clip

Dmitry Sinkevich is a master of form, and the Atmos represents the very best aspects of his work. It cuts an attractive figure, with futuristic angles that somehow meld perfectly into my medium/large hand. It also manages to be more comfortable, practical, and carriable than its premium cousin.

Don’t believe me? Let’s break it down point by point. First, the grip. While I always adored the 0450 from an aesthetic standpoint, its hand-feel is always a bit of a disappointment. This is partially due to personal preference, since I find slab-sided titanium blades to be more difficult to grip. I’ll take G-10, Micarta, or even Grivory any day of the week. The Atmos’ G-10 and carbon fiber overlay provide solid purchase, even with damp or greasy hands. The jimping along the finger-facing portion of the flipper tab is a thoughtful touch, as well. While some may find it to be a bit aggressive, its extra friction really holds my index finger in place. Though we’re used to seeing flipper tabs pull double duty as blade guards, the setup on the Atmos feels extra secure.

Next, let’s cover the practicality of this blade. The hollow grind glides through onions, carrots, and cardboard with genuine ease. Yes, 8Cr13MoV is nowhere near as good as the 0450’s S35VN. But the grind, in conjunction with the thinness of the Atmos’ blade stock, allows it to cut far longer than you’d expect from a cheap Chinese steel. The ZT, on the other hand, features a saber grind with a tendency to split foods rather than slice.

We’ll wrap this portion of the review with a discussion of carriability. When I say that the Atmos is easier to carry than the 0450, I’m really making two different statements. On the scientific side, this is simply a more pocketable design. It weighs almost an ounce less than the titanium model (2-ounces vs. 2.9), and the deep-carry pocket clip is far superior to the semi-high ride affair on the ZT. It also manages to produce less of a hotspot under firm grip.

On the more personal side, I’ve found this to be an easier knife to use. Like, if someone asks me to cut a plastic tie-wire from a segment of steel grating, I’ll always hesitate before pulling out the 0450. It’s an attractive, expensive knife, and I find it difficult to shake the fear of dinging it up. But with the Atmos? Hell, it’s only $30. What do I care if the blade accidentally knocks up against a rock or piece of structural steel? It’s a more capable cutter, without the nagging pocket-jewelry connotation. Sure, it’s not the most hard-use tool on the table, but let’s be honest – Neither is the 0450.

Deployment and Lockup

The Kershaw Atmos is a fidgeter’s dream. I’ve spent more time playing with this knife than any other in my collection. Even the ZT0450 pales in comparison when it comes to fidget factor. There’s just something about the Atmos’ deployment – The snikt/clack that lands pleasantly on the ear.

The linerlock itself lands at a solid 40-50% lockup, with the blade flying through its arc after a firm press on the flipper tab. Kershaw has dialed in the detent to the point that it’s actually rather difficult to cause a misfire. Here’s a breakdown shot of the Atmos, showing the internal hardware responsible for its excellent action.

As you can see, Kershaw has included both metal washers and captive bearings. The setup works well, though the arrangement is a little strange. On the show side, the bearing is sandwiched between the washer and blade. On the clip side, the bearing rests between the washer and the linerlock steel. This is something you’ll need to remember during reassembly, if you want the blade to remain centered.

And you will need to take this blade down. See that deep hook on the blade tang? After household chores and a weekend of camping, gunk started to accumulate in its inner recesses. Thankfully, the simple screws and D-shaped pivot make disassembly a relatively routine affair. As mentioned, just be sure you’re putting the washers and bearings back in the proper order.

Even with proper oiling, however, the blade’s swing isn’t completely utterly smooth. I still encountered a bit of rolling friction when working it back and forth manually, but this is more than covered by the strength of its detent. When firing with the flipper, you’ll never notice.

Kershaw Atmos Review – Final Thoughts

Take a deep breath, fellow knife nerds. I have a confession to make: The 0450 is on its way out of my collection, while the Atmos is staying for the foreseeable future. It’s not a question of cost, since the ZT was provided to me for a previous review. Rather, it’s an issue of usability. Yes, the 0450 is fun. Its fit, finish, materials, and design place it in the pantheon of great EDC knives. But, for all of the reasons discussed above, I find myself drawn to the down-to-earth usability of the Atmos.

That isn’t to say the Kershaw is perfect, however. I’d love to see an upgraded version, maybe with 154CM, 14C28N, or another budget-friendly steel. Dmitry Sinkevich has come up with a world-class design here, and it deserves world-class materials. But, with an entry price of just $30, this is one of the best budget EDCs on the market.

UPDATE: Kershaw has chimed in on the Atmos’ use of carbon fiber. Here’s what they had to say: “The one thing is that the carbon fiber on the handle is not a ‘sticker’. It is actually an integral part of the G10 handle material. For this knife, when they are making the G10 (which is an epoxy-fiber material), they make it by layering sheets of fiber with epoxy…but in this case, the top is composed of two thin layers of carbon fiber. So rather than being stickered on, the carbon fiber is part of the handle—just like all the other fiber layers in the material. The black G10 below is exposed when we machine the contours of the handle. There’s no way the carbon fiber would peel off as a sticker might.”

Kershaw also takes issue with the idea that 8Cr13MoV is a “groaner of a steel.” As their representative pointed out, Blade Magazine/KnifeForums has singled the company out as having attained the best heat treatment for this particular metal. I stand by my desire to see the Atmos in something a bit higher-end, but it’s good to know that they’re getting the most mileage out of ol’ 8Cr.
