Review Viper Knives Swayback Jack (A CK Exclusive)

Excellent write up and thank you Padruig for shedding light on a company/knife that I feel is somewhat neglected. I must say your swayback has the nicest European stag I’ve seen.

I also own the Viper stag swayback and it's bigger brother, the stag sowbelly. Both knives are superb in size/fit/finish/action. The Sowbelly has terrific ergos in the hand as well and I encourage anyone to give it a try. One very nice feature of the swayback over the sowbelly (and other lambsfoot/swayback designs) is the fact that the swayback blade is pinchable.

These LE knives may not be as "traditional" as GEC but the Viper fills my niche of ultimate "grab and go" traditional. No worries about hard use or use in the rain or humidity with titanium/M390.

These knives punch way above their price. IMO they are great additions to a traditional lineup.

The sowbelly is in my pocket today

Good write-up Dylan :thumbsup:
It's nice to see it compared to others in this pattern segment. And nice effects on the photos. They're rich and deep.
I like my Swayback a lot.

I agree that the stag is really nice on these, as is the fit/finish, and the M390 is very, very good. These are definitely a step up from run-of-the-mill offerings: zero play, good centering, etc... The size of the package is also a really nice sweet-spot. I'm happy to have the lanyard hole as it allows some adornment and carry options, but this is always up to personal taste.

The pull is quite strong, which translates to a fine, authoritative snap, as you mentioned.

In my mind these could be even better perhaps with polished bolsters/liners-- more in keeping with the polished backspring.
And offering a lockback version of this... how about that?
I'd be first in line to get one :)


knives like this are like a '33 Ford hotrod built with modern drivetrain and chassis. Modern enough that you dont worry about how its built or it's reliability, but with old school looks and design thats just plain cool.
Excellent analogy :thumbsup:
 
Great write up. Italy has really stepped up in the moditional market. I am a little surprised others have not emulated.

Others have emulated. The difference being that they have not had an eye to retaining historic shapes of traditionals. But, since the EuroBarlow debut, there have been many companies bring a modern slipjoint to market. Where they miss the boat (in my opinion), is that they disregard the historical character. They try harder to make a modern knife into a slipjoint, than making a traditional knife with modern materials.
 
I have a LionSteel Roundhead, Maserin Plow, Viper EZ Open, and Viper Swayback all have been good knives. I got one of the first versions of the Plow and it was solid but the 2nd version which I have now is so much better for me mostly the slightly thinner handle. The EZ Open is great if you don't mine the less traditional mechanics of it and I would say the 2 Viper models I own have been my favorites so far.
 
Thanks a lot, Dylan: I have been trying to get my knife buying under control and you have to go and wave this knife under my nose! I am powerless. PayPal is quick and easy. I never get tired of sitting by the mailbox! Ha.
 
Dylan, you have done us all a great service with this extensive and well-thought-out review. I have one of Mike's ram's horn Bolus drop points in M390, and think it's the finest blade steel I've yet seen on a traditional. Do you see, feel, or have noticed any difference between the Viper's M390 and the lionSTEEL's? Just lately I've been carrying my GEC #47 Viper in 440C, and the slightly smaller Maniago version with the upgraded steel is pretty appealing to me. I'm not sure, now that you've tweaked my impulse, how long I can hold out! ;)
 
I think there might be a thread that discusses the subject knife already but as I am stuck at home with not much better to do, I thought I would write up a post/review with regards to it in a weighty, in-depth manner.

***DISCLAIMER***

The subject knife is a modern take on a traditional pattern, utilizing modern materials and construction methods. Because of this, it is somewhat controversial in these circles and there are bound to be comments that question its presence here on the Porch. I invite all manners of discourse but please do bear in mind that this knife meets the criteria set by those who make the rules.

Onward!

The knife that I am writing about is the Swayback Jack, made by Viper Knives from Italy, in collaboration with Mike Latham from Collector Knives.

Specs:
  • Swayback Pattern
  • M390 Steel (with a hardness between 59-60HRC)
  • Titanium Integral Bolsters and Liners
  • Stag Covers
  • Wharnecliffe Blade
  • Closed Length - 3 5/8"
  • Overall Length - 6 1/2"

Mike Latham has collaborated with a few Italian cutlery firms to bring the market a number of traditional patterns with a more modern flair. Pairing a classic design with premium materials (PM alloy steel and titanium) and more modern construction methods (screwed construction, washers, adjustable pivots, etc.) has been met with a fairly positive response.

My first foray into Mike’s collaborations was the Lionsteel Roundhead – one of his Euro Barlows. Since then, I have acquired the other versions of the Barlow (Dom and Shuffler) as well as the 2-bladed Warhorse (a favorite). I also tried out the Lion Steel Bolus which falls somewhat in the Sodbuster area. Despite the Bolus not fitting my hand all that well and my initial skepticism overall, I’ve been very pleased with these offerings and I feel that Mike has been blazing a unique trail amidst the world of traditional cutlery – offering us high quality production knives in desirable patterns and with premium materials at an excellent price.

Now to dig into the meat of this Swayback Jack.

The Swayback frame is one of my favorites and occupies a significant portion of my collection. When I learned that Mike was working with Viper Knives to produce this one, I knew that I was eventually going to have to get one. Due to the scarcity of GEC’s #47 pattern and no word as to whether we will be seeing them produce another run anytime soon, I am unable to compare this Viper with GEC’s… well… “Viper”. However, I can compare to Case’s Swayback Jack and GEC’s #93, as well as several Sheffield made Lambsfoot knives.

Coming in at 3 5/8” closed, it is slightly shorter than the #47 and even shorter still than the #93. It is, however, comparable to the standard Lambsfoot size from A. Wright’s and longer than the Case Swayback Jack.

As a result, the size of this Viper Swayback should hit a sweet spot for many and even if the length is too short for some, there is a lot packed into this knife to make it worth the purchase.

One of the most interesting elements of this knife (to me, anyway) is the integral bolsters and liners. Machined from a single piece of titanium for each side, it really does a great job at streamlining the knife and serves to make my Euro Barlows somewhat clunky and/or busy in comparison. Another difference between the Viper and the Lionsteel is that the backspring of the Swayback is almost polished, where the backsprings on the Barlow have more of a satin (or matte) finish.

Like with my Lion Steel knives, all the transitions on this Viper are beautifully chamfered and smooth, nothing catches, gouges, or scratches. Which makes for a wonderful knife to carry, use, or simply fidget with. Fit and finish is just excellent.

Another interesting thing to note is the backspring near the pivot. Mike discusses this in a video on his website and explains how it is part of the design. In more traditionally made knives, we would certainly accuse this of being proud of the liners in not only the closed position, but at the half stop and open positions as well. However, due to the design, as well as the rounded shape of the spine and backspring, it doesn’t seem out of place on this knife. In fact, when the knife is open, the transition from spine to spring is almost seamless.

I cannot recall what all the cover options were when Mike initially got these in but when I eventually got around to ordering, there were only Stag, Grey Oak, and OD Canvas Micarta covers available. I’ve become rather fond of Stag so I inquired with Mike to see what variants were available. Despite the current climate, Mike was very responsive (as he usually is) and informed me that the Stag coming in from Italy has been quite good. I’ve had better luck with Mike picking out my Stag as of late than I ever have been in selecting my own and this time was no exception.

I like color and texture in Stag and value those over matched covers and specific types of texture (i.e. popcorn, grooves, etc.). Though I like dark and gnarly in general, I am perfectly happy with plenty of color and lots of texture.

The covers that came on this knife are mostly matched in thickness, with the pile side being a tad bit thicker and, in my opinion, if I’m to have additional thickness, the pile side is where I want it. Fantastic color and texture on both sides, with the pile side having some tasteful smooth white spots here and there.

Very, very pleased with them.

When discussing new slipjoints, it is impossible not to talk about the action or “walk-and-talk” and the strength of its pull. The Viper Swayback Jack has an excellently firm pull that snaps securely into the half stop and open positions – no “mushiness” here, it’s like biting into a fresh Honeycrisp apple. Closing it is equally as crisp and satisfying – a job very well done here and even though I am likely able to make some adjustments via the pivot screw, I don’t have a need in this case.

Like the other Italian slipjoints, this one has a stop pin, which in my experience gives a different feel when snapping closed than a knife without one. As they say, your mileage may vary...

Speaking of pivot screws, the one on this knife is rather large and I suspect it will turn a lot of folks here off to the knife overall. I won’t speculate as to why it is as large as it is but from a tinkering viewpoint, a larger screw makes it a bit easier when (or if) the need arises.

One of my favorite blade shapes is the Lambsfoot – it combines the strength of a Sheepfoot with the nimbleness of a Wharnecliffe. It is really hard to beat in terms of form and function and is why I have so many of them. That said, I do appreciate a good Wharnecliffe and this Viper has a good Wharnecliffe.

It is a stout blade with relatively thick stock but even with the thickness, they have done an excellent job with the grinds. (I don’t have any calipers handy but I am pretty certain that the blade is thicker than the blades on my Lion Steel Barlows.) Still, with the nicely tapered grind, relieved spine, and keeping the thickness behind the edge down for the most part, this is going to make for a fine, albeit robust, slicing tool.

So far, there is nothing for me to really dislike about this knife. If I were to really nitpick, I would say the lanyard hole is unnecessary for a knife in this size range but that is just my preference. I also would prefer that the lanyard holes have eyelets to protect against the wear from a bail or cord but I understand that due to the modular nature of these knives, it probably wasn’t particularly feasible.

In conclusion (if you have made it this far, you have my thanks):

Overall, this is a knife that is representative of the great quality that I have come to expect from not only Italy, but from Mike Latham as well. The collaborations are unique in this industry and reflect a facet that might not be everyone’s cup o’ tea but there is no denying that there is a place for these knives and represent an evolution that is both desirable and exciting.

Glamor shot!

Well done young man .

Excellent review Dylan , I prefer to carry a larger traditional along with my lock back or fixed blade but I had to get this sway back (OD Canvas Micarta) and I’m glad I did. I was next going to purchase the Grey Oak but decided not to, your stag looks great but even though I still own a few stag folders I don’t think I will ever buy another. Not much to add to your write up but I’m really impressed with the pull and action with this sway back, it’s superb. I’m not one to give the best reviews, my only complaint and it’s cosmetic is my knife came to me with a jagged laser etch along the spine like a bad scratch but since I bought it as a user and not a collectible I just blew it off, not much else to say but I do highly recommend this knife.
 
Thank you, folks. It really was quite the pleasure posting this - not like I don't have the time... I suppose one of the few positives (maybe the only positive) with regards to GEC being shut down at this time is that it gives me more freedom to explore other knives and the companies that make them. So far, not only have I acquired a decent number of nice fixed blades, I've got my eye on other Italian made slipjoints and some nice Bokers as well. I may do other reviews in the not so distant future if folks aren't opposed to it.

Grest review and write up,I appreciate it coming from a fellow knife knut.Certainly is a nice looking knife to me, my only personal gripe from an aesthetic view is the screws. Not that it uses them really,but that they're torx. I get it from a manufacturing standpoint, but their kinda "bleh" to me on this style of knife. I think if they used slightly dommed slotted screws like you find on fine firearms they would be more appealing. At least for me,others may feel differently. I feel this and the Lionsteel knives bridge the gap between modern and traditional nicely. We must remember that like my nephew who just turned 21 and for him it seems laptops and cell phones have "always" been around,so to for his generation modern tactical folders are the norm. There are those who get burned out on a particular thing and want to try something new but having features they're used too helps them take the plunge. For them knives like this are like a '33 Ford hotrod built with modern drivetrain and chassis. Modern enough that you dont worry about how its built or it's reliability, but with old school looks and design thats just plain cool.

That's a nice analogy, David, and I think you've hit the nail on the head with it. I would agree with regards to the slotted screws - most old slipjoints with screwed construction are shown to have slotted screws and of course, many firearms are the same. I am not sure I would like this knife as much with slotted screws though - I'd be trying to get all the screws to line up and that is apt to drive me nuts. Maybe if the pivot screw was slightly smaller...

Uh... not to hijack the thread,but what about pruner/hawkbill kniveso_O
Be hard to imagine one of those not being a swayback:D:thumbsup:

Yeah, I completely forgot about pruners and such. You, of course, are absolutely correct.

Excellent review, something substantial yet not opinionated, a proper piece to get your teeth into:cool:

I think these type of knives from Italy, and Lionsteel, Fox knives show not only ingenuity but that it's possible to produce a very high quality, rigorously assembled knife that's within many peoples' grasp financially. An achievement in itself. I've been very impressed by the Lionsteel Roundhead even though Barlows have not been my favourite pattern, it's light but exudes quality and presence-I do like a decent Spear as well. Yesterday I got a Fox Knives Livri and I'm delighted with it, the M390 steel is most impressive.

Overall, the Viper looks very satisfying and is a credible size, not too massive like other Moderns can be. I think it could look very nice with Ramshorn or Ivory Smooth Bone too, something for Mike to mull over :cool: I'll say that I'm not really a lanyard hole fan, particularly on a Barehead like this but that's just subjective, the Wharncliffe blade has the right handle:blade ratio too.

Thanks, Will

Thank you, Will, and I agree with your thoughts. Had this Swayback been available in Rams Horn, I would have leapt at the chance - the Rams Horn on my lionSteel offerings have all been rather exquisite.

Excellent write up and thank you Padruig for shedding light on a company/knife that I feel is somewhat neglected. I must say your swayback has the nicest European stag I’ve seen.

Thank you, Ron. I have to wholeheartedly agree with regards to the whole "grab and go" sentiment. There is comfort knowing that the tool you have in your pocket isn't going to be negatively impacted by the elements. On one of my last crabbing/fishing endeavors, I had a lionSteel Barlow in my pocket. It was so nice not having to worry about getting wet with all the splashing around that happens in a small crab boat. And, quite frankly, you couldn't ask for a better stainless steel, in my opinion.

Good write-up Dylan :thumbsup:

Excellent analogy :thumbsup:

Thank you, my friend. The polished backspring is certainly an interesting contrast with the matte titanium and I would certainly be curious to see the bolsters/liners with a bit of polish - that could likely win over some folks as it might take away from the modern aesthetic in a big way.

I also wanted to mention my Swayback is the Grey Oak and the pictures currently on CK don't do it justice it is beautiful and I love it.

I was sorely tempted by that Grey Oak - it looks like lovely stuff. I think I recall it was supposed to be Blue Maple but there was a mistake at the factory - I think it was a good mistake.

Dylan, you have done us all a great service with this extensive and well-thought-out review. I have one of Mike's ram's horn Bolus drop points in M390, and think it's the finest blade steel I've yet seen on a traditional.

I'm not sure, now that you've tweaked my impulse, how long I can hold out! ;)

Thank you, Jeff! Honestly, M390 ranks amongst my favorite modern steels - it holds a great edge for a long time, isn't too difficult to sharpen, and is fairly tough. In terms of how Viper's compares to lionSteel's, that's a good question. I would venture to guess that since both companies are from the same city, it isn't without the realm of possibility that it is close to the same stuff but I will have to let Mike chime in on that as he is better versed on their sources.

So far, it feels very similar - I will get a better idea once I've had a chance to do more cutting with it.

The steel comes from the same maker and is treated by the same lab - thus any difference comes from the factories preferences in treat itself. Both series test in the "excellent" range on ISO 8442.5 standardized edge retention test.
