Kershaw Volt II Review

Last Updated: August 8, 2019
It has been too long since I’ve examined a nice budget EDC blade. This time around I picked up a Kershaw Volt II, and could immediately tell that I grabbed a real winner. First off, the original Volt is a true collectors piece. It’s not a particularly old design, but it’s a limited edition titanium framelock with a composite steel blade. It will to run you a few hundred dollars at least. And that’s if you can find one.

Kershaw went in the opposite direction with the Volt II. Here they opted for everyday affordability with nice, but inexpensive materials. The two blades do share a lot of similarities, as they are both creations from designer R.J. Martin and have generally the same shape. The major differences are that the original Volt is much larger (1.75″ longer) and costs about 15 times as much as the Volt II. For right around $20 pretty much anyone can afford the Volt II, and to be honest I think you would be foolish not to. Lets take a closer look to see what I’m talking about.

General Dimensions

The Volt II has an overall length of 7″, a 3.125″ blade and weighs 3.4 ounces. This is a nice size for EDC and should be a fairly friendly looking carry regardless of where you live.

The blade is a drop point shape, with a small swedge and nice sweeping belly. The entire blade has been bead blasted, which is familiar territory for a lot of Kershaw’s small EDC blades (like the legendary Kershaw Skyline). The tip on this knife is very good, holding a good amount of steel all the way to the very end. Kershaw finished this one off with a high hollow grind and a nice smooth edge.

Blade steel is the very high value 8Cr13MoV stainless from China. My experiences with 8Cr13MoV have been very good. For the money, I really don’t think you can beat it. It is capable of taking a very nice edge and has good rust resistance.

Handle, Ergonomics, and Pocket Clip

The Volt II features full stainless steel liners with injection molded plastic scales. The plastic is actually pretty dense (Kershaw calls it Polyimide) and I am quite pleased with it. An attractive triangle pattern has been emblazoned over the scales and the liners have been lightly milled out. I’m sure some would prefer G10, but for price I am not complaining. I really like how the liners have been given the same blasted finish as the blade – looks real sharp. Rounding things out is an almost full backspacer made of the same Polyimide material as the scales.

Ergonomics on the Volt II are nice. First off, it is a smaller handle (~3.8″) so I found it slightly cramped with my larger hands. That said, I managed a full grip and liked how the thick and rounded scales felt in hand. There are two shallow choils and an integral guard to keep your fingers from slipping. A nicely jimped thumb ramp provide addition support on top. My only suggestion would be to make the handle a little longer to provide some extra room but I think for most people the ergonomics are going to work really well.

The pocket clip is a kind of funky looking Kershaw clip. Having handled a number of Kershaw knives I’m no stranger to their somewhat unconventional clips. As you can see this one is quite interesting. In practice, the clip works just fine and is not nearly as funky as some of the others I have run into. I would have liked to have seen it be a little bigger, but it’s discreet and offers a low carry. On the subject of carry, this is a chunkier folder with a thickness of about half an inch. For some, this may be a little difficult to carry. I don’t mind it but everyone is different. One last thing to note is that this tip allows for tip up or tip down carry but it is right side only.

Deployment and Lockup

The Volt II takes advantage of a nice flipper for deployment. This knife uses Kershaw’s Speedsafe assisted opening technology. This knife fires open hard with a really satisfying click. The flipper also doubles as a guard – a feature I have really come to appreciate with a lot of Kershaw designs. I’m also a big fan of the Speedsafe – Kershaw has done an excellent job with all of the assisted opening knives that I have handled. I predict that if you pick this one up you will spend way too much time playing with this one (at least I did).

Lockup is accomplished through a liner lock. This is actually a pretty thick lock bar and it locks up nice and early on my example. I noticed zero blade play and I love how the knife has come perfectly centered. A small amount of jimping on the lock bar makes this an easy one to disengage when you want to, but it still feels very secure in hand. For EDC tasks this lock will be able to handle it all.

Kershaw Volt II Review – Final Thoughts

Sometimes I get a knife in and the review just writes itself. I was impressed with the Volt II the moment it came out of the box, and I still haven’t put it down. If you want an EDC knife in the $20-25 this is a very strong option in my book. What really makes this one for me is the way it’s been put together. The fit and finish are phenomenal. The knife locks up nice and early, the blade is perfectly centered, deployment is smooth, the grinds are nice, the handle feels great – I could go on and on.

To me this is a great example of what Kershaw does best – putting together a rock solid EDC folder that everyone can afford. My only issue would be that I’d like to see an ambidextrous clip and perhaps a slightly larger handle. Aside from that the knife has exceeded my expectations in every way. I want to note that the Volt II is made in China, but the quality control is excellent. I would put the level of fit and finish above my Spyderco Tenacious and wouldn’t hesitate to recommend this to anyone interested in the knife, or in need of an inexpensive folder that can take some real use.

SOG Aegis Review

by Dan Jackson 19 Comments

Last Updated: August 26, 2019
The term “aegis” has ancient roots. Commonly used in Greek mythology, aegis means “protector” and has been often symbolized in the form of a shield. In many ways the ]SOG Aegis is emblematic of a protector as well.

If ever needed the Aegis could certainly offer its user security – be it helping in some emergency utility task. or perhaps by performing in a more tactical role. While the knife was not imbued with any mythical powers, the light weight and wicked blade are quite enchanting, and are among many reasons to consider adding this knife to your collection.

General Dimensions and Blade Details

The Aegis has a 3.5″ blade, an overall length of 8.25″ and a weight of 3.1 ounces. This is a medium sized folder and depending on who you are, could be on the larger side for EDC. The weight of only 3.1 ounces is exceptionally lightweight so if carrying a bigger blade appeals to you this is a good option.

The blade on this knife is a long leaf shape and comes with a plain (non-serrated) edge. Made from 1/8″ stock this blade terminates with a needle sharp tip. Seriously, the tip on this thing is incredible. The full flat grind and absence of a swedge enhances this feature and the blade shape is excellent for thrust cuts and piercing.

However, you will want to be careful with prying or stabbing into hard materials as the unenforced tip could break. This isn’t necessarily a negative, you just want to bring the right tool for the job. If prying is your modus operandi go to the hardware store and pick up a crowbar. The edge came absolutely razor sharp with a beautiful job done on the grinds. As an emergency tactical knife I think this blade shape is highly effective. For EDC tasks there is ample belly and great slicing capability with the full flat grind.

As you can see in the photographs, you have a couple different options for finishes. Shown here are the satin finished blade (with matching silver hardware) and black titanium nitride (TiNi) coated versions. Both are beautifully done. I love the satin finish SOG puts on their knives, but the TiNi coating wins points for hiding finger prints and the general “stealth factor”. I have found the coating to be very durable – this isn’t some inexpensive coating that will rub off. It will wear with use, but expect it to hold up favorably to cheaper painted teflon coatings.

The Aegis comes in AUS8 stainless steel – a very nice mid range Japanese stainless steel. I love the keen edge AUS 8 takes and the ease of sharpening. I haven’t noticed any issues with rust and the steel resists chipping. SOG cryogenically heat treats their AUS 8 which provided enhanced toughness and better edge retention. I think AUS8 was a good choice and SOG really knows how to work with this steel.

Handle, Ergonomics, and Pocket Clip

Like the Flash II, the Aegis has a glass reinforced nylon (GRN) handle and lacks metal liners. The GRN on the Aegis is of high quality and feels good (not cheap and plasticy). This is a closed back design. Due to the absence of liners, it’s a very lightweight handle.

The ergonomics of the Aegis is also very nice. With a 4.75″ handle there is plenty of room for my larger hand and it naturally offers a comfortable 4 finger grip in both forward and reverse positions. I love the flowing lines of the handle, it fills the hand and provides great visual balance.

Grip has further been enhanced with “digital” texturing and all the corners have been smoothed and rounded. SOG embedded rubber inserts into the handles which provide extra feedback and grip. Additionally, the back of the handle and spine of the blade have been given some jimping. Oddly, the jimping faces towards the tip but it does offer grip. Especially the TiNi version. I think the satin finish has rounded the “bite” off just a little. Personally, I think it would offer more grip if the jimping was oriented in the opposite direction, but the current configuration does provide some traction.

The choil area has been given some texturing, a sort of enlarged jimping or “scalloping” if you will. This helps lock the index finger in place and provides more tactile response. All in all I love the ergonomics on the Aegis – it’s obvious a lot of time was put into designing the handle.

The pocket clip is SOG’s bayonet style clip. The clip allows for ambidextrous tip up carry, rides ultra low, and provides excellent retention. “SOG” has been cut into the clip, which I don’t mind, especially on the blackened version. All in all it’s a discrete carry.

Deployment and Lockup

Like many of SOG’s folders, the Aegis is an assisted opening knife. The spring on the assist is very good at shooting the blade out with a satisfying snap. The thumb studs are large and ambidextrous. It’s easy for me to get my thumb behind the stud and the knife flips out effortlessly.

Lockup is done through SOG’s Arc lock. This style of lock is similar to a Benchmade Axis lock or the ball lock found on the Spyderco Manix 2. It is essentially a type of bolt lock. It’s a secure design that can be easily engaged. Lockup is quite secure on both of my Aegis knives with a microscopic amount of bladeplay in one and none in the other. This is a great accomplishment from a linerless design, and I was really impressed with how tight these knives locked up. One minor complaint (or wish perhaps?) would be to get the arc lock positioned on both sides. I know SOG does this on some of there more expensive folders, and would probably drive the price up (while providing a diminishing amount of utility). As a left handed user it would make the knife easier to close with one hand.

Also, like many of SOG’s assisted openers, there is a built-in safety. The safety is a nice option and I believe it’s part of the reason why SOG can offer this knife in tip-up carry (my preferred form of carry).

SOG Aegis Review – Final Thoughts

I have really enjoyed owning both of my Aegis’s (Aegi?) and believe that they could live up to their namesake.

Whether it’s helping you build shelter from a storm, or working as a tactical knife, the light weight and smart design is an excellent blend of form and function. And I have to admit, I love the form aspect of this knife. This is an awesomely balanced knife combining a big blade, fast deployment, robust lockup with a light and easy carry weight. Fit and finish is excellent, and the price (around $50) provides a lot of quality knife for your money.

Kershaw Needs Work Review

by Dan Jackson 12 Comments

Last Updated: August 21, 2019
In my opinion the wharncliffe is one of the most under-appreciated blade shapes out there. Many may write the shape off as a novelty, but in my experience a wharncliffe blade can be incredibly useful for a lot of every day tasks. That’s why I wanted to make sure I eventually got down to reviewing one of my favorite production knives with a wharncliffe blade, the Kershaw Needs Work.

Buy the Kershaw Needs Work at BladeHQ

Buy on Amazon

At first glance this knife appears to be more at home on the set of an “Aliens” sequel than in your pocket. This is another Ken Onion design, and one of his more radical blades. I’ll admit, the look of the Needs Work had to grow on me a little, but I quickly warmed up to it. Today I really like the looks of this knife and the performance as well. I think Ken and Kershaw did a great job representing the “wharnie” here.

Purpose

To provide a little context, I would mainly classify this as a utility knife. That is, a knife that is used to cut a lot of boxes, leather, carpet, etc etc – a dedicated work knife for your shop or tool box, or to be carried while working a physical job with a lot of cutting tasks. The wharncliffe shape essentially provides a 3 inch razor blade, and the fine tip allows for unmatched precision.

I am hesitant to classify (or recommend) this as a full blown EDC knife, mainly because it doesn’t carry particularly well. However, it all boils down to what you want to use the knife for.

General Dimensions and Blade Detail

The Needs Work has a 3″ blade, a 4 1/8″ handle and weighs 3.5 ounces. This is a stout little folder designed for light and medium duty use. As you are well aware by now, the NW has a wharncliffe shaped blade. The NW’s blade is .12″ (3mm) thick – this is a thick piece of metal for a small folding knife.

From a design standpoint, Ken Onion gave this blade some of his characteristic flair. The blade includes gentle sloping curves and a nice little swedge. It’s a simple design that I really like. A hollow grind begins about half way down the blade.

The tip on this knife is exquisite, and will let you make very precise cuts. If you go through a lot of boxes, or cut stuff like carpet I highly recommend this blade shape. The angled handle only accentuates this feature. On the flip side, the fine tip means it could break – if you do a lot of thrust cuts or want a “hard use” knife I’m not sure the tip will hold up.

My Needs Work came with that gray matte finish popular on a lot of Kershaw knives (like the Skyline). You may also be able to find this knife with a black titanium nitride coated blade as well.

Kershaw went with Sandvik 14C28N stainless steel for the blade here, a steel I am very familiar with. It holds a very nice edge and sharpens easily. My only advice would be to keep an eye out for rust, I’ve noticed a couple small spots form on my Skyline.

Handle Ergonomics and Pocket Clip

The Needs Work has a beefy handle with glass-filled nylon scales over full stainless steel liners. The thick handle offers good grip, but makes the knife a little harder to carry. The scales have been given a really unique pattern. It’s got a kind of organic alien looking vibe to it. I am not crazy about the pattern, but it’s not really seen as a negative either. There is a full backspacer and the liners have not been milled out.

The ergonomics on the Needs Work are pretty good. I noticed a lot of people raving about the ergos, but I found the handle to be a little small for my relatively large hand. I can squeeze all 4 fingers on the grip, but realistically, this is a 3 finger knife for me. It’s still a comfortable knife but my pinky does feel a little lonely there. The thumb ramp and choil are well defined and there is adequate jimping on both. The thick handle does feel good and the textured pattern provides some response. For some reason I really like throwing the NW into a reverse grip; the handle is well suited for it.

Perhaps the biggest ergonomic feature is the angle of this handle. This allows you to take full advantage of the fine tip. The Needs Work could be a great knife to cut dry wall, carpet or similar flat materials. I found it to be very convenient when I had to trim some posterboard for the background on my little photography studio. More conventional blade shapes (and handle angles) would make you rotate your wrist further to use the tip of the blade for precision cuts. The Needs Work is a much better design for those kinds of tasks.

Sadly, the pocket clip is something of an abomination. Right off the bat, you are limited to right-side tip-down carry only. Furthermore, the large (ugly) clip rides high in the pocket, adding insult to injury. In practice, I actually found the tip down carry to be OK given the flipper and assisted open. I’d much rather see some mounting options and a little more conventional looking clip. The clip and thick handle are the two main reasons why I am hesitant to recommend this as an EDC blade.

Deployment and Lockup

Deployment on the Needs Work is awesome. This is a speedsafe assisted opening knife, and the spring on this the NW shoots the blade of this knife out like a gun. This is a wicked fast deployment that makes an awesome cracking sound as the blade locks open. This is one of my favorite assisted openers; the cool blade shape and rapid deployment are too much fun.

Opening is only accomplished through the flipper – not an issue here at all.

Lockup on the Needs Work is equally impressive. The NW uses a very interesting liner lock that requires no stop pins. The tang of the blade locks into the liner at two different places. It’s hard to describe but very solid in practice. There is zero blade play in this knife, which is awesome when you consider how much force this lock is put under by the assisted opening.

Kershaw Needs Work Review – Final Thoughts

I really like this one. The unique blade, the chunky design, the lightening fast deployment and super solid lockup – these are all major plusses. Also, I found the wharncliffe blade to be uber useful. That tip allows you to do detail cuts like no other knife. I also love how the Needs Work was made in America, and can be found for right around $30. Also, the fit and finish on mine is great. Blade centering is perfect, the grinds are smooth and even – everything was well put together. This is a knife I am proud to add to my collection.

That said, I do ding the knife a little for it’s pocket clip – that’s my only real issue here, and to be honest it still carries pretty well considering. If you want a rugged utility knife, or are searching for something a little different I recommend the Needs Work.

SOG Flash II Review

by Dan Jackson 28 Comments

Last Updated: July 29, 2019
SOG is a company that has always intrigued me. They have eschewed the more mainstream model of production knife design, which typically involves a team of in-house designers and a deep roster of freelancers, instead favoring a one man approach. All of SOG’s knives are designed by president and founder Spencer Frazer. This has resulted in some unique design elements and ultimately, some very unique knives.

Buy the Flash II at BladeHQ

Buy on Amazon

The Flash II is a shining example of this, a knife that is quintessentially SOG and decidedly different. This blade has been around the block a time or two (it’s been in production for years), and has passed through the hands of thousands in its various iterations. Today I turn back to the classic drop point version with a plain edge and black handle.

Purpose

For purposes of this review, I am classifying the Flash II as a medium sized EDC and emergency tactical knife. With it’s big blade, grippy handle and assisted opening, the Flash II could easily fill an emergency tactical role. Also, due to the number of different finishes and handle choices available, this could very well be a collectable for fans of the brand.

General Dimensions and Blade Specifics

The Flash II has a 3.5 inch blade, and overall length of 8″ and a weight of 3.1 ounces. Going back to the purpose of this knife, I think the combination of the long blade and light weight make it an interesting emergency tactical option. It also could be practical for EDC if you like a bigger blade but don’t like being weighed down (the Flash I is a smaller version, perhaps more appropriate for EDC).

The blade shape is a very traditional looking drop point. It’s a no frills design with a full flat grind (“FFG”). As something of a traditionalist, this simple style of blade always appeals to me, and the FFG is great for slicing. My Flash II came with a very nice satin finish and a meticulously ground secondary bevel. The satin finish is a finger print magnet, and I find myself constantly wiping this knife down… That probably says more about me than the knife, but it’s something I noticed.

Of course, as one of SOG’s classic models this knife comes in a couple blade shapes (wharncliffe, tanto, and the drop point version shown) and you can also get this blade with a Titanium Nitride (TiNi) coating and some even with tiger stripes.

SOG selected AUS8 blade steel for the Flash II. If you are into steel then you already know about AUS8, it’s a mid range Japanese steel. If you aren’t that into steel, then know that AUS8 takes a sharp edge and holds it pretty well. It’s easy to sharpen and very forgiving. SOG does a cryo treat on this blade which is supposed to improve toughness. I find AUS8 to be entirely adequate and fits the mid range price tag well.

Handle, Ergonomics, and Pocket Clip

The Flash II has a unique, boxy looking handle made of thick fiberglass reinforced nylon (FRN); a reinforced plastic. Some versions sport an aluminum handle and you can find the FRN version in a dozen or more colors. I like the FRN version as it keeps the knife light and doesn’t feel cheap. This is a much denser FRN than what is on say, a Benchmade Griptilian. There are no liners in this handle, which helps with the weight but isn’t without disadvantages (discussed below)…

Ergonomics on this oddly shaped handle are surprisingly good. It’s a chunky design and has no problem filling the hand. The corners have been slightly rounded. For normal use it’s comfortable, and even when holding the handle tightly and carving off long curls of wood it wasn’t that bad. I wouldn’t want to build a tree fort with this knife, but for most tasks I’d say the handle works well. I do like the thumb ramp and dual choils. They help provide control for detail work. The sides of the handles have been given a diamond texture and help with overall grip.

The pocket clip is an ultra deep carry design and is reversible. It’s a tip-up only clip and provides strong retention. It’s kind of a funky looking, definitely another look distinct to SOG. There is also a very small lanyard hole next to the clip.

Deployment and Lockup

The Flash II has an assisted opening. A gentle push on either of the ambidextrous thumb studs snap the blade out in a “flash.” Stupid puns aside, the opening is quick and smooth. Assisted openings can be a matter of taste, but I like it on this knife, especially as an emergency tactical folder. Rapid fool-proof deployment under stress is what I’m looking for an an emergency tactical blade, and the Flash II provides just that.

There is a safety lock on the side of the handle. When the safety is engaged it prevents accidentally opening the knife. For many this will be about as useful as a sock on a chicken’s foot, but it allows SOG to make this assisted opener a tip-up carry knife so I don’t mind. I just leave mine in the “off” position and go about my day.

The Flash II uses what seems like a combination between a bolt lock and a lock back. It’s hard for me to really tell without taking the knife apart, something I’m not quite ready to do. I found that there was some side-to-side play when I had the blade open and locked. I tried adjusting the pivot, and was able to fix it somewhat, but there was still play evident in the blade. Given that this is a linerless design, with what appears to be some sort of bolt lock, I am not really surprised by this. If there was up-and-down play (there wasn’t) I would be concerned as that would suggest that the lock could fail.

If you can live with a little side-to-side play in your knife then I don’t see this as a major issue. If blade play is something you can’t stand, or want to really hard use this knife, then keep this in mind.

SOG Flash II Review – Final Thoughts

All in all I am very happy with the Flash II. I love the blade, can appreciate the light carry, and find the assisted open to be both fun and practical. It’s a quirky little knife that really stands out in a crowd. As a fan of choices I think this is a good thing. The only real negative I could find was the blade play. I’ve done some reading and know I am not alone, but that doesn’t stop this from being a classic folding knife enjoyed by many.

If you want something lightweight, practical and a little different, then I suggest checking out the SOG Flash II.

Kershaw Blur Review

by Dan Jackson 22 Comments

Last Updated: February 20, 2019

While I enjoy reviewing all kinds of knives, it’s the mid size edc “working man’s” knives that I especially enjoy reviewing because these mid size EDC’s are what spend the most time in my pockets and in my hands. The Kershaw Blur is such a quintessential mid size EDC knife that a full review is long overdo.

Buy the Kershaw Blur at BladeHQ

Also, I can’t ignore the fact that this another Ken Onion design. Ken Onion is the man behind a lot of the knives I have reviewed (such as the CRKT Ripple), and his designs are very famous for their flowing shapes. In contrast some of his other work, the Blur looks fairly pedestrian, but it is a good size knife with a very functional design which is part of the reason why I think the Blur has become so popular.

General Dimensions and Blade Details

The Blur has an overall length of 7.875″, a 3.375″ blade, weighs 3.9 ounces, and is made in the USA. It’s a medium to large size folding knife. I would classify this as a larger EDC knife or a tactical knife.

The Blur comes in many flavors and there is a little something for everyone with different colors, blade steels, handle inserts, and blade shapes. The “standard” Blur comes with a nice hollow ground drop point blade, but you also have the option of a tanto blade and there is even a blunt tip version for EMT and rescue applications. You also have the option of plain edge or partially serrated. Kershaw also sells this knife with a black DLC (Diamond Like Coating) on the blade – it’s an attractive option and wears really well.

In addition to that high hollow grind, there is also a slight recurve on the edge (which is more pronounced with the rescue version). The recurve is slight, which keeps this knife reasonably easy to sharpen. There is a swedge running along the top which keeps the tip of the drop point version strong.

In practice the Blur is a formidable slicer. The slight recurve and hollow grind make the knife excellent for cardboard. The tip provides a good combination of strength and piercing ability. This is designed to be a work knife, and I don’t hesitate to use it in that capacity.

As for blade steel, the base model comes with a fairly unassuming Sandvik 14NC28 steel blade (shown here). This is a good mid range steel, ideal for EDC. It takes an edge easily and holds it well. I have had no issues with rust – especially with the DLC coating. I would put 14NC28 above AUS-8 but below 154CM.

Kershaw also offers the Blur in S30V, CPM154CM, and a even a composite blade with Sandvik 14NC28 with a ZDP189 edge. I have also seen this knife in 440A, 420HC, and few others. The S30V version is especially popular, and a number of limited editions have been released over the years. There is a steel here for every taste (and every budget).

Handle, Ergonomics and Pocket Clip

The first thing you will notice about the handle is the sandpaper looking inserts. Kershaw calls this “Trac-Tec” and it is actually a rubberized material that provides plenty of traction without tearing up your hands. The rest of the handle is made from anodized 6061 aluminum and features a flow though (pillar construction) design. All in all this is a very strong design. The handles are very nicely finished and relatively light weight – I have no complaints.

The ergonomics of the Blur are excellent. This simple handle gets out of your way and affords a comfortable grip for small and large hands alike. There is a short run of jimping on the gently sloping thumb ramp. It provides just enough traction to index your thumb and hold it in place. The rubber trac-tec inserts aren’t my favorite feature of the knife, but I must admit they provide plenty of grip. All the corners have been rounded and the knife feels natural in hand. Perfect for getting plenty of work done.

The pocket clip is fairly well executed. Depending on your particular model, it comes with a matte black finish and rides pretty low in the pocket (not “super” low, if that is something you are looking for). It does allow for tip up or tip down carry, but it is not ambidextrous. One thing I especially like is how Kershaw doesn’t include their Trac-Tec texturing where the clip touches the handle. This makes the knife much easier to remove from the pocket (although I do find it sometimes hangs up a little.

Deployment and Lockup

Kershaw opted for ambidextrous thumbstuds here. The thumb studs are cut at an angle and dig into your thumb. One review I read said that the thumb studs looked like a “stair case” which is actually a pretty good description. Some people love these thumb studs, others hate them. I find that they work alright for my purposes. I think that these thumb studs work best with an assisted opener, but I think they are a little fiddly and not my favorite.

Being an early Ken Onion / Kershaw collaboration, this knife comes with Ken’s Speedsafe assisted opening system pre-installed. I am not the biggest fan of assisted opening knives, but the Speedsafe on the Blur is robust and the action is good. Of course, you can always take the spring out and reduce the Blur to a 100% manually opening blade if that is what you prefer. There is a small detent so the blade won’t fall out of the handle if you take away the assisted opening spring.

The Blur features a liner lock. I think the lock works well here, especially in the EDC and backup tactical roles. The liner engages early and the lock-up is strong with zero movement. The whole deployment and lockup aspects of this knife is a real plus in my book because it is very smooth. Kershaw knows how to put assisted openings and liner locks together and the Blur is an outstanding example of that knowledge.

Blade centering on my knife is pretty much perfect.

Kershaw Blur Review – Final Thoughts

The Kershaw Blur is a modern classic. Offered in a myriad of different blade steels and handle colors, there is a little something for everyone. This is one of Ken Onion’s more restrained designs for Kershaw, and the clean lines of the Blur has garnered it broad appeal, and the knife continues to sell well even years after it’s release.

In fact, the knife has developed something of a cult following among enthusiasts of high end knives. This is a humble blade, but it makes for a great beater. I respect the Blur in the same way that I respect the Cold Steel American Lawman, Buck Marksman, and Hogue EX04 (these are among my favorite folders with ~3.5″ blades). This is a tough working knife and was designed to be used.

The Blur is made in the USA, is well constructed, features quality materials, and is priced reasonably – usually between $45 and $75 depending on the trim level. This everyman’s folder gets a lot of things right, and for that reason I have included it as one of the my recommended EDC knives.

CRKT Ripple Review

by Dan Jackson 17 Comments

Last Updated: August 4, 2019
The CKRT Ripple is a design that had me doing a double take. The flowing lines and sharp looks were very “Ken Onion-y” and upon closer inspection the knife was in fact designed by Ken Onion. It turns out Mr. Onion has parted ways with the folks at Kershaw and he has been picked up by competitor CRKT.

The Ripple was one of Ken’s first designs for CRKT. It’s something of a gentleman’s EDC knife, with Ken’s signature flowing curves in a low profile package.

General Dimensions and Blade Details

The Ripple comes in a few sizes. What you see here is the large version with a 3 1/8″ blade, an overall length of 7 1/2″ and a weight of 2.9 ounces. This is a nice size for an EDC knife. Not only is the Ripple lightweight at under 3 ounces, but it’s thin too. The whole knife is less than 5/16″ thick. Plenty of blade in a lightweight package. It’s a slim design that begs to be carried.

The blade is an attractive drop point design. There is an absence of the typical organic curves that Ken Onion is known for, but it still has his style and I find myself wanting for nothing. This is a really slender and refined blade and it comes with an exquisite tip. The swedge running 3/4 of the top of the blade is another elegant touch and the high hollow grind makes this a nice slicer as well. Personally, I love this blade shape.

CRKT has released this knife in several different steels over the years, but 8Cr14MoV is going to be the most common configuration. 8Cr14MoV has been discussed at length before, but this is a Chinese steel that is best known for being expensive, easy to sharpen, and holding an adequate edge. It’s on par with AUS-8, but below VG-10 and 154CM in the steel hierarchy. Feel free to check out my knife steel article for more information on different types of steel.

Handle, Ergonomics, and Pocket Clip

The handle of the Ripple is either made of 420J2 stainless steel (the framelock version) or aluminum (the linerlock version – shown here). The handle pieces have first been CNC milled with a ripple pattern. The handle has then been either a blue or black titanium nitride coating and then has been rubbed to reveal the silver look of the steel. It is a very unique look and can be difficult to capture in photographs although darkchild69, our featured photographer, has done an excellent job here. Another design element is the series of 44 small holes milled into the side of the handle. This is more for decoration I think, although it does lighten the handle up slightly. Finally, the handle is bolted together with two pillars. Very simple and as always, very easy to keep clean. This is a very slim handle and all the detail is unlike anything else currently on the market.

This is a thin metal handle so logic would suggest that this won’t be the most comfortable knife. In fact, the ergonomics are surprisingly good. The handle has been rounded and the flipper helps define the choil. Additionally, there is nice jimping on both the thumb ramp and handle. This provides plenty of traction and makes this a very easy knife to use for general tasks.

The clip is another interesting component. It is mounted high for tip down carry. It sits flush with the top of the handle and follows the line of the handle. One gripe is that the pocket clip it is tip-down right hand carry only. With the assisted open and the flipper, I can totally see why CRKT opted for tip down carry, but with 44 holes already in this knife, they really need to drill a couple more and make this clip ambidextrous.

Deployment and Lockup

The Ripple is a non-assisted open knife actuated by a flipper on the back of the handle. Those familiar with Ken Onion’s Leek, Chive, ZT 302, etc will be very familiar with this style of deployment. The flipper has been given some aggressive jimping that really bites into your thumb, you will not be slipping on this flipper. There are no thumb studs.

An interesting feature of the Ripple is the IKBS opening system. IKBS stands for “Ikoma Korth Bearing System” and means just that. There are a total of 16 ball bearings (8 per side of the blade). The bearings are uncaged and sit in little grooves machined into the handle and are used in place of teflon or phosphor bronze washers. Initial impressions are very good – the bearings make for a very fast and smooth deployment. This is one of the smoothest opening knives currently on the market (production blades at least). The IKBS combined with the assisted feature makes for effortless blade presentation. And apparently the bearings do not need much maintenance, which is good because I would not want to take this knife apart.

Here is an update from 2019: Over the past 8+ years I’ve owned countless bearing equipped knives. Generally they have held up real well. The versions with caged bearings are easier to take apart. This IKBS equipped knife includes loose bearings. You can take these knives apart too, but you need to be careful. Here is a great video from CRKT on how to clean an IKBS equipped knife.

The Ripple uses a steel frame lock, which is plenty strong for the kind of EDC tasks this knife was designed. Due to the intricate design on the handle you can hardly tell the framelock is there. I like how this looks and I also like how the framelock and adds to the simplicity of the design. However, I have noticed on multiple knives, the framelock extends very far over (see below) while others lock up early. Frame locks are designed to slowly break in and will travel over with extended use. Having the lock engage “late” from the start means that you may get less life out of the lock. If you get a Ripple with this late lock up, I would recommend talking with CRKT and getting it fixed because in my opinion, this shouldn’t happen with a new knife.

Here is a parting size comparison with my Boker Plus Urban Trapper:

CRKT Ripple Review – Final Thoughts

The Ripple is a beautiful knife. Ken Onion took a sexy blade shape and melded it with a wonderful handle. This knife “flows” from an aesthetic standpoint and I think the design is just phenomenal. The IKBS is both interesting and functional, long term testing will tell if this is a mere novelty or truly a revolutionary way to deploy a blade. The Ripple is made in Taiwan, which we now know (thanks to Spyderco) is capable of making some great higher end blades at a terrific value.

All things considered the CRKT did a great job with the Ripple. I would prefer if they re-worked the pocket clip so that it was ambidextrous, and a little less weird, but beyond that you get a lot of nice knife for the money. The Ripple is one of the knives that laid the foundation for Ken Onion / CRKT collaborations, and continues to be a great lightweight high value option for folks years after its original release.
