assisted opening

SOG Twitch II Review

I’m hardly the first to say it, but the rise of well-designed manual flippers has really thrown the value of automatic knives into question. When already-good flippers are paired with assisted-opening mechanisms, true autos are obviated ever further.

That said, my beef with many assisted-opening flippers is that they’re chasing an aspect of autos I find unnecessary at best and obnoxious at worst: actions that kick the blade so vigorously into the stop pin that they generate recoil. So aggro! If you ask me, the spring assist only needs to be strong enough to work with the momentum of a moderate flip.

While I can’t speak to SOG’s other assisted opening designs, the Twitch II is a knife built for me. Its action is decisive without being aggressive, and there’s a whole lot else to recommend it besides.

General Dimensions and Blade Details

The Twitch II puts a lot of performance into a small package. The body of the knife is just a hair over 3.5” long, a half inch at its widest point (including the clip!), and an inch and an eighth deep from flipper to closed blade spine. My brass-handled Twitch II was a relatively stout 3.58 oz measured on my digital scale, but you could trim that weight by a full ounce by opting for the aluminum scaled version if factory specs are to be trusted.

As you might note from the size comparison with a Spyderco PM2 and an Ontario Rat II, the Twitch II is a decidedly small knife. Often, I throw my Twitch II loose into a pocket. I notice the heft for the first few minutes I’m carrying it around, but it’s not long before I stop thinking about it. Just by feel, the clip and flipper tab make it very easy to orient and deploy the knife one-handed.

I can’t say enough good about this blade. At 2.75”, the drop point is long enough to perform medium-duty work. However, it is supremely, awesomely slicey. Fans of Spyderco’s blade grinds will find themselves comfortable here given the Twitch II’s full flat grind and well-sharpened, extremely uniform secondary bevel. Thanks to a thin stock that measures just 2mm at its widest point and a good amount of belly right where it needs to be, the knife cuts extremely well.

I’m not kidding. From the factory, my Twitch II came hair-popping sharp and made effortless confetti of stray paper. Having recently bought a Spyderco Chaparral, one of the company’s most well-lauded slicers, I think the Twitch II gives it a real run for its money at about a third of the cost.

The blade is made from AUS-8, which while being far from a “super steel” will likely hold its edge a bit longer on a small knife like this. And, if it happens to dull, even a novice can restore it back to a hellacious level of sharpness with only a modicum of effort.

What I can’t figure out is why SOG saw fit to put the patent number along the side of the blade. Do they imagine some Chinese counterfeiter is going to get the knife in hand and say “Aw, damn!” when he sees this arbitrary series of numbers? As if that’s what’s going to stop some unscrupulous overseas outfit from trying to reverse-engineer the design? It’s a frankly ugly and unnecessary detail that detracts from the Twitch II’s clean lines.

Handle, Ergonomics, and Pocket Clip

Ergonomically, there’s a lot to like. The balance point of the knife (at least on my brass version) lies almost exactly at the center of the handle, making the Twitch II feel very lively and precise in the hand. The very gentle inward slopes direct the thumb and fingers to little nooks where everything feels just right, and there are no sharp edges anywhere beyond the cutting edge. The Twitch II has the feel of a very precisely crafted tool in all respects.

Like a great number of pocket clips, I think the one included on the Twitch II is too stiff. It also exposes a good five-eighths an inch of knife, which is conspicuous for one as small as this. More reasons why I just throw mine in a pocket. However, I do really like the unintentional ergonomic function of the clip: it gives the middle finger a great little hollow to find its way into and provide a secure point of contact.

Even though the knife is extremely smooth, all of these little ergonomic details allow me to feel like I’ve always got a confident, secure grip on the knife. No aggressive texturing needed!

Deployment and Lockup

As mentioned before, the action is delightful. The flipper is designed as a “push button” style (as opposed to the “light switch” method I often employ on other knives). Overcome the detent, and the blade will deploy firmly, but not excessively. It announces itself with a gentle “snick” rather than something that sounds like a gunshot or an anvil falling off a table. However, if you want to rely on the Twitch II’s thumb studs, you can deploy the blade that way and watch it literally rocket out and into deployment.

I’d mentioned I often carry the Twitch II loose. Comforting for me is the safety, which I can click upwards and not have to worry about the knife deploying when I don’t want it to. The detent isn’t exactly weak, but the safety is an appreciated “belt and suspenders” option to ensure the blade stays closed. Additionally, those who want to push the knife a little harder can use the safety to lock the blade in place once it’s engaged. Just for that little extra piece of mind.

The Achilles heel of the Twitch II, if you can even call it that, is a little bit of blade play. There’s no wobble front-to-back, mind you, but you can induce a little lateral play if you grab the blade and move it. This is hardly a reason for me to throw the Twitch II into the nearest river.

As for centering, it’s pretty decent by default. Kicked into deployment and folded into closure, the blade is in perfect parallel with the liners. Assuming you’re not wiggling it merely to disappoint yourself.

SOG Twitch II – Final Thoughts

The word “gentleman’s knife” gets thrown around quite a bit, but I’m surprised SOG’s Twitch II doesn’t come up more in the discussion. It’s a very functional (but not aggressive) knife with an easy deployment system, great build quality, and svelte dimensions. Dress the Twitch II up in its rosewood or anodized aluminum variants, and it looks even more the part. My brass-and-black version has a neat steampunk aesthetic that I think would turn heads without freaking out one’s coworkers. I’d argue the Twitch II is too small and too sophisticated to threaten a reasonable person.

Naturally, I think the great action, excellent ergos, and superior cutting performance right out of the factory are enough to recommended the Twitch II to enthusiasts reading this site. However, I think this is a wonderfully giftable knife for any gearheads or gadget freaks who have a penchant for dense little simple machines that do a job well.

As a final side note, SOG’s product mix is better than ever. A neat knife like the Twitch II is proof enough the company is interested in diversifying beyond the “hard dude tactical operator” aesthetic a number of people (fairly) associated them with in years past. This is a great knife for a great number of different users, and remarkably easy to recommend.

Kershaw 1870 Knockout Review

by Dan Jackson 13 Comments

I have always been a huge fan of user knives. Blades like the Benchmade 710, Spyderco Gayle Bradley, and Cold Steel American Lawman have always resonated with me as great knives because they are great tools. As a collector I am still enthused by the latest and greatest in materials and technology, but I will always have a soft spot for unpretentious tool knives that work really well. These users are what spend the most time in my pocket, while the fancier blades spend the most time on the shelf.

Enter the Kershaw Knockout. Here we have a bold drop-point blade married to a simple handle. The knife has visual presence, but it still appears utilitarian, has an interesting sub-frame lock mechanism that combines the strength of a frame lock with the weight of a liner lock, is made in the USA, and retails for around $55-65 depending on where you buy it.

I am especially drawn to this price because the $50-100 price point is notoriously tough for the retail knife industry. It seems that there are a lot of new releases where the knife retails for less than $40 or more than $100, but relatively few knives are coming out in the $40-100 range these days. Looking at pictures, specifications, and the bottom line, Kershaw potentially has a really nice user knife here, and for that reason I am excited to finally acquire one for my personal collection and share some thoughts on it with you.

General Dimensions, Blade Details

The Knockout has an overall length of 7.875″, has a 3.5″ blade, and weighs 3.8 ounces. This is a good size knife, but it’s surprisingly thin and lightweight. It’s not totally unreasonable to consider this as a daily carry, and it certainly makes for a great utility knife for weekend projects, or for folks who can get away with carrying a bigger knife on a daily basis.

The blade shape is a classic drop point that has been punched up with some well placed lines. I really like how broad this blade is relative to the handle. It has great presence and is innately appealing. It is also very practical. The belly is deep and the high flat grind peters out to a thin yet serviceable edge. The knife cuts really well. The thin grind coupled with the broad profile makes for an excellent slicer.

This knife is ideal for breaking down boxes and other slicing tasks. I cut through rope, and performed some food prep with no issues. This isn’t my ideal choice for a carving knife, and the thin blade doesn’t lend itself to hard use, but this is a great practical blade that cuts very well. There is a swedge but the tip is reinforced and comes to a fine point; excellent for piercing. The end result is the Knockout cuts well in a variety of scenarios. It’s not going to be the toughest blade, but if you respect it, the Knockout will get a lot of work done.

Blade steel is Sandvik 14C28N, a Scandinavian stainless steel that has made a number of appearances in USA made Kershaw knives. I’m a fan of 14C28N, especially when given a lightly tumbled finish like on the Knockout. This is a proven steel for me. It holds a decent edge and is easy to maintain, and the blade geometry of the Knockout makes great use of this fine-grained steel. I have found that 14C28N will stain if you aren’t careful with it (and was difficult to clean up for the photographs), but that will hold true for a lot stainless steels. I think 14C28N is a great choice for a value oriented EDC knife.

Handle, Ergonomics, and Pocket Clip

The Knockout has a black hardcoated aluminum handle with partial plastic backspacer. The black anodization on the handle slabs is reasonably durable, but will show signs of wear with use. Handle construction is simple and sturdy with two body screws threading all the way through the backspacer and handle. Everything lines up very nicely and has been well finished. The show side of the handle features a few arcs carved into the face of the aluminum for a little visual interest and traction. This is a sturdy handle and I find little to complaint about it.

The ergonomics of the Knockout are adequate. Being a thinner handle, this doesn’t jump out at me as outstandingly comfortable, but it certainly works and it doesn’t have any glaring hot spots. The anodized aluminum provides a little traction and isn’t slippery. There is no jimping anywhere on the knife. I don’t mind this but I recognize that this is a personal preference. People looking for a more hard use knife might want to go with something a little thicker and with more traction. The Knockout was fine for my pedestrian purposes, but the thinness of the handle, while great from a weight and carry perspective, could turn off those who are looking to run this knife hard on a regular basis.

The pocket clip on the Knockout is the same one found on the Cryo. It’s a blackened deep carry fold-over clip that has been mounted high on the handle and drilled and tapped for 4 corner carry. I like this pocket clip design and have zero complaints regarding the clip, carry options, or way this knife holds in the pocket. My favorite aspect of the Knockout’s handle is how thin it is. I have really come to appreciate this, especially in a larger knife. It carries very well.

Deployment and Lockup

The Knockout is an assisted opening knife with the option of a flipper or ambidextrous thumb studs. I am not always crazy about assisted opening flippers, but on the Knockout it works and I actually like it. The blade responds quickly to a push of the flipper or brush of the thumb studs. These are true thumb studs, not blade stops on some other flipper folders (like the 0560 for example) so they are easy to get at and work flawlessly. The knife kicks open easily and locks in place with an authoritative “thwack”.

The Knockout makes use of a sub-frame lock to lock the blade open, and is the namesake for this knife. You probably already know this from doing other research on the knife, but the aluminum handle has been “knocked out” to accept a stainless steel lock bar, hence the name “Kershaw Knockout”. This is actually the first sub-framelock knife to grace the pages of BladeReviews, and is a really nice design. The hardened steel lock bar engages at around 50%, there is no blade play or lock stick, and the knife is still very lightweight for it’s size because the rest of the handle is aluminum and plastic. It’s a great practical design that has been well implemented. No complaints here.

I will mention that my blade is fairly off center. It doesn’t rub, but is worth noting.

Kershaw Knockout Review – Final Thoughts

The Knockout is a very solid offering from Kershaw. I have had my eye on this one since its release, and I am glad that I finally managed to get my hands on one. $55 gets you a well made American flipper folder with quality materials, a practical footprint, and an attractive design. For those wanting a larger knife capable of getting some real work done without breaking the bank, the Knockout strikes me as a good choice. There are definitely higher end and more exotic offerings, but the Knockout is a great no-nonsense tool and doesn’t have a whole lot of worthy competition at its price point.

I will also say that I have tended to favor the USA made Kershaw’s over their Chinese made counter parts. The USA Kershaws are always really well done. The materials are a little nicer, the finishes seem better, and I have just had better luck with them for whatever reason. This isn’t intended to start some sort of flame war, but I’m just calling it as I see it. I’d rather spend $55 on a USA made Kershaw than $20 or $30 on a Chinese one. To me the Knockout is an example of Kershaw at its best.

Benchmade Volli Review

by Dan Jackson 19 Comments

Last Updated: July 27, 2019
I’m not sure how to put this delicately, so I’ll just come out and say it: Benchmade hasn’t done a whole lot of exciting stuff in 2013, and it has resulted in a lack of reviews on new Benchmade knives. This isn’t necessarily a bad thing, but the lack of cool new stuff to examine makes for boring blogging.

Buy the Benchmade Volli at BladeHQ

Buy on Amazon

One 2013 Benchmade has been on my radar for some time, and that is the Volli. It hasn’t gotten a lot of attention, probably because it appears to be some sort of a rehash between the Griptilian and Barrage, but again that isn’t necessarily a bad thing. And frankly there is a lot to like here. In the time I’ve spent testing out the Volli I’ve found it to be a very functional and practical knife. We sometimes overlook those qualities as the industry focuses more and more on big names and exotic materials, but I still think there is room in many people’s pockets for a robust EDC/tactical knife without a lot of frills or hype.

General Dimensions and Blade Details

The Volli runs the gamut from an urban EDC to a “tactical” pocket knife depending on where your needs and preferences lie. For me, it’s more of a nights and weekends knife than a true daily carry, but for many I’m sure it would do well as an EDC. It has a feature set that I would think appeals to the law enforcement / military crowd, and I’m sure Benchmade also had those types of users in mind when they put this knife together.

The drop point blade is clean and simple with a high flat grind, and fine tip. My model comes in a bright satin finish although they do offer a black coated version as well. The grind lines are crisp and the knife came wickedly sharp out of the box. This is a simple drop point pattern but it has been done right.

The blade is S30V, a steel that I haven’t always been a huge fan of despite it’s popularity and billing as a premium knife steel. In practice I’ve found that S30V has a reluctance to take a really fine edge, especially on a couple Spydercos that I own, and I’ve sometimes dismissed it as more trouble than it’s worth. Well, I’m pleased to say that whatever Benchmade did with the S30V on my Volli, they really did it right. This is one of the nicest S30V blades I have owned.

The Volli came screaming sharp out of the box, which is always nice, but more importantly I’ve been able to keep that screaming edge with some judicious stropping. The knife has proven itself to be a really capable cutter. As always, I did test this knife thoroughly. I went through a great deal of 1/2″ sissal rope without any problem – it was almost comical how easily it cut through the rope. Eventually the edge slowed down, but I was able to quickly bring it back with my strop. Same went for wood and cardboard – it cut large amounts of both with no problem. This is because of the relatively (2.5mm) thin blade stock and the nice lean grind. 2.5mm isn’t alarmingly thin but many EDC blades (like my Spyderco Sage 1 – also in S30V) comes in at 3mm. While some may find the thinner stock a turn off, I like it because the knife cuts, and it cuts damn well.

Handle, Ergonomics, and Pocket Clip

The handle of the Volli is G10 over full skelotonized stainless steel liners. Probably the first thing you will notice is the heavy texturing to the handle, but it’s also important to point out that it has a full plastic backspacer and you can’t access the pivot without taking off the display side scale. Construction is sturdy. All the parts line nicely while corner of the handle has been broken to accommodate your hand. There is a small unobtrusive lanyard hole and all the hardware is of the torx variety.

Ergonomically, this is a straight forward and practical handle design. Relative to something like the Griptilian this is a thin handle, but there is still plenty there to fill your palm and all the corners are nicely contoured. I found it to be comfortable, even under hard use. There isn’t any jimping, which is fine in my book. I was able to really bear down on the knife when carving and cutting and I didn’t notice any major hotspots. Much like the simple blade shape this is a practical handle, and I found it to largely be a pleasure to work with.

The pocket clip is Benchmade’s classic split arrow clip. This time it has been configured for ambidextrous tip up carry. The aggressive texture to the G10 means this knife will destroy your pockets if you aren’t careful (you will never find me carrying this with slacks), and that may be my greatest gripe. I understand that there is a fine line when designing a knife like this, and you don’t want something that offers no grip at all. Aside from the pant shredding texture the Volli carries well. This is a classic pocket clip and it holds the knife securely and discretely.

Deployment and Lockup

The Volli takes advantage of Benchmade’s axis assisted opening technology. It snaps opens quickly with the brush of a thumb. An assisted opening knife is mostly a novelty for me, but I can see the advantage if you are in a line of work where you really need your knife to open. Benchmade included a safety located on the back of the handle. It stays out of the way but can lock the knife in both the open and closed position, a nice feature when you have a tip up carry assisted opening knife.

For lockup Benchmade went with their trusty axis lock, a personal favorite. My knife came with a small amount of lateral play, and I had to tweak the pivot by removing the G10 scale. The covered pivot looks nice, but it’s a departure from the otherwise practical design and I’d be remiss to not consider it a problem with the design.

In addition to the axis lock there is a secondary locking mechanism on the spine of the handle. It allows the user to lock the blade in either the open or closed position. It’s not a bad feature to have on a tip-up assisted open knife. It’s unobtrusive and functional.

I have to say that after Michael commented on this post (see below) I both de-assisted the knife and I took the secondary lock out. I don’t proclaim to be an expert when it comes to disassembling knives, but I’ve taken down plenty. The Volli was a little tricky to take apart and the whole process took me the better part of a half hour. That said, if you are patient and don’t mind potentially voiding your warranty it shouldn’t be impossible. The knife works just fine without the spring and the safety.

Benchmade Volli Review – Final Thoughts

The Volli isn’t a show stopper. It isn’t the latest and greatest. It’s no ZT 0560 or Spyderco Domino as far as the “wow” factor is concerned. But I’m still pleased with the knife and it seems to fill a spot in Benchmade’s catalog. Detractors of the Griptilian’s plastic handles may have finally met their match, and I’m impressed with how nicely the knife cuts and feels in hand. The thinly ground blade is one of the best slicers I’ve handled in recent memory, and the S30V steel performed way better than I’m used to seeing out of S30V.

If I were designing it from scratch I’d tweak a couple things. I’d leave it so the pivot could be readily adjusted, tone back the texture slightly and (if it were me) remove the spring assist. But these are all pretty minor and subjective complaints that may not be relevant to your needs or preferences. While I’m not completely head over heels with the Volli, it is still a very nice knife, and I’d go so far to say that if you are someone looking for a robust folder in the 3.5″ blade category with S30V steel I’d put it above the Zero Tolerance 0350 and say it is very strong competition for the Spyderco Paramilitary 2.

It may not be a runaway blockbuster blade of 2013, but that isn’t because it’s a bad knife, it’s because it has been overshadowed by some very interesting and very adventurous offerings in a very competitive marketplace. If you are in the market for a sturdy high performance folder in S30V with a ~3.5″ blade, then the Volli is well worth your consideration.
