Boker Kwaiken Flipper Review

Last Updated: January 10, 20198
Back when the original Boker Kwaiken came onto the scene I was pretty excited. Modeled after knifemaker Lucas Burnley’s custom offering, this sleek design looked too cool to resist. That is, until, reviews started to pour in. People stated that the knife was difficult to open and the tip of the blade protruded out from the handle to the point where it would inadvertently cut you. No bueno. My excitement instantly turned to disappointment. Rather than buy the knife, and then slog through writing a review of something that I knew I wasn’t going to be happy with, I just decided to skip the Kwaiken entirely.

Despite the poor reviews, the Kwaiken developed its own cult following. This is thanks in great part to those in the knife customization crowd. Knifemaker / knife modder Alexander Dietz developed his own cottage industry around the “Dietz modded Kwaiken”. Clever dremel work converted the clunky Kwaiken into a nice little flipper. Whether Boker listened to customer feedback, or was planning on doing this anyway, they eventually offered their own flipper version of the Kwaiken.

This knife was hotly anticipated by many collectors, including myself, partially because it appeared to address some of the issues that plagued the original Kwaiken: the inability to open the knife easily, and the renegade tip. If that wasn’t enough, this time Boker decided to slather the knife in titanium. Bearings, flipper, titanium, and a fresh design from a hot custom knifemaker – yup, this one follows the formula that many enthusiasts are looking for these days.

I am going to see if this updated model is worthy of the hype, or is more of the same.

General Dimensions and Blade Details

The Kwaiken Flipper has an overall length of 8.375″, a 3.5″ blade, and it weighs 5.4 ounces. I hate to sound like a weight weenie but the first thing I noticed was how heavy this thing felt. It is a chunky knife and feels like a little metal brick. You would think that the relatively thin titanium scales would actually shave weight off the Kwaiken, but it’s over an ounce heavier than it’s non-flipper counterpart. Personally, that relegates the Kwaiken Flipper more towards the collectible category, and away from being a true EDC. Regardless, I am sure plenty of guys will enjoy carrying this knife, and there is nothing wrong with that.

The blade shape is a modified drop point. It is a sleek and dramatic blade shape that tucks perfectly into the thin handle. The tip is very fine and the knife is well suited for stabbing things. It has a hollow grind and the blade finish is very nice. The lustrous stonewash hides wear well and is more resistent to corrosion than a beadblast. For what it is, I like this blade shape.

Steel on my particular knife is Aus8. Given that this knife sells for more than $100, I heard quite a few grumblings about the choice of steel on both this and the original Kwaiken. Given that this knife was made in China, I don’t think Boker had a ton of options to choose from. Still, 154CM, S35VN, or some other higher end steel would have been nice given the price point. Personally I don’t have a problem with AUS8. It’s a hearty steel that sharpens easily and is fine to see on user knives. I can totally understand if some folks take issue with the AUS8.

Since purchasing the knife months ago, it looks like Boker now offers the Kwaiken flipper in an “upgraded” steel: V10. I wouldn’t call VG10 a huge upgrade over AUS8. In fact, I prefer Aus8 because I find it a little tougher than V10. Neither are fantastic edge holders but for EDC work they will get the job done.

Handle, Ergonomics, and Pocket Clip

The compact handle of the Kwaiken flipper is built like a little titanium tank. Thick full steel liners are under generous 3-d machined pieces of titanium, all supported by a solid titanium backspacer. Construction is simple and solid.

I really like the minimalist look of this handle. The way the liners shadowbox the titanium scales, and how the closed blade hides completely within the handle make for a very attractive design. The handle has a monochromatic appearance, although upon close examination the steel and titanium are slightly different colors. I am sure many knife modders view this piece as something of a blank canvas. I hate to spoil the party, but I enjoyed the look of the original Kwaiken with its micarta handles, and would prefer the contrast and lighter weight of micarta over the heavy titanium version. Still, the build is very good and the added weight does make the knife feel very substantial.

The Kwaiken Flipper feels good in hand. The simple design means this knife will work for a lot of people with different size hands. There is no jimping or really texture to speak of, which could be a good or bad thing depending on your preference. The only ergonomic “feature” is that the flipper doubles as a forward finger choil, allowing you to choke up on the blade a bit for more controlled cuts. All said I don’t have a problem with the way this knife handles and didn’t notice any hot spots or other ergonomic issues.

The pocket clip is a right side tip-up only affair that mirrors the design of the handle shape. It is simple and unobtrusive, and I like the way it looks. It holds the knife in your pocket pretty well, although I think the spring could be a hair stiffer. This is a heavy knife and the handle is smooth. While it has never fallen out of my pocket it doesn’t take a ton of effort to pull it out. I think a little more clip strength would be valuable here.

Deployment and Lockup

Obviously this knife uses a flipper for deployment. I am somewhat puzzled by the design of the flipper tab as it actually bows out where the index finger goes for deployment and is sort of slippery. It works but I think it could been designed to be a little easier to open. Still, the knife opens with a snap and flips well, thanks in part to the IKBS bearing pivot system. The detent is OK. It’s not going to flip like one of the new ZTs or anything, but the detent is adequate and the knife flips open with a snap.

For lockup you have a stainless steel liner lock. Mine engages around 90%. The steel is thick and the lockup feels very reassuring. There is no blade play or lock stick. This is a well implemented liner lock. The blade on my knife is pretty much centered.

Boker Kwaiken Flipper Review – Final Thoughts

The Kwaiken Flipper is a cool design and has been well implemented. I know it has been a good seller for Boker, and when you look at it on paper it is easy to see why. That said, I’d love to see Boker continue to refine this one as it is such a nice design. They have already moved in that direction by upgrading the blade steel, but I think they should also explore offering a lighter weight version of the flipper with a different handle material. I think the inclusion of both stainless steel liners and full titanium handle scales is a bit overkill and adds unnecessary weight.

I haven’t mentioned this yet in the review, but this is part of Boker’s “Plus” line, and is manufactured in China. Fit, finish, and general quality is very high on this knife despite being manufactured in China.

Also, I’m almost glad they didn’t go with a framelock here given Boker’s history of issues with titanium framelocks. I’d rather see a well implemented liner lock, than a messed up frame lock.

In closing, this is a cool little design and a memorable offering from Boker. I recommend it if you are into the design and are OK with the weight.

Rick Hinderer Knives XM-18 3.5 Review

by Dan Jackson 16 Comments

Last Updated: June 23, 2019
In the past I have compared knife collecting to mountain climbing. Certainly there isn’t the element of physical accomplishment, as the only thing that really gets a workout is your wallet, but there is that spirit of pursuit and of course the ascent up a pile of incrementally more expensive knives. When considering the “summit” in the realm of production knives three big players in the US market come to mind: Chris Reeve, Strider, and Hinderer.

Buy the Hinderer XM-18 at BladeHQ

Buy on Amazon

I have been tooling away at this website for the better part of 4 years now, and have already covered multiple Chris Reeve and Strider products, but I’ve yet to review a Hinderer. That is because I had yet to purchase a Hinderer until 6 months ago.

The reason it has taken me so long to review a Hinderer is the same reason why many people get so hung up on Hinderer knives in general. They are difficult to purchase unless you win a lottery at one of the knife shows Hinderer goes to, happen to qualify for Hinder’s active military / first responder program and buy directly from Hinder, or want to pay a substantial mark up for a Hinderer on the secondary market. With a retail price from Hinderer of $385, these knives were selling for $700, $800, $900+ on the forums. We could get into a huge debate as to whether they are “worth” the money. At the end of the day, they are worth what you will pay for them.

Over the past few years I have seen the secondary prices creep down a little, and was able to snag this new XM-18 3.5″ for $550. At that price I was comfortable buying the knife knowing that I could eventually sell it and recover most if not all of my money. Your mileage will vary.

General Dimensions and Blade Details

The 3.5″ XM-18 has an overall length of 8.25″, weighs 5.6 ounces, and of course it sports a 3.5″ blade. This is a very substantial tool. It is over half an inch thick, and was definitely not designed for desk jockeys like myself. Rick comes from a firefighting background, and built the XM with first responders in mind.

It’s a big and heavy knife designed to perform under the hugely demanding situations first responders run into. I run a small law office on the coast of Florida. The closest thing I come to being a first responder is responding to the office manager’s announcement that someone dropped off a dozen donuts in the break room. On weekends I mow the lawn, go to the beach, and occasionally write articles about pocket knives. Some might suggest the 3″ XM for someone like myself, but I have always wanted to check out a 3.5″ flipper slicer. So here we are.

The blade of the XM is Rick’s classic drop point shape. We have seen something similar to it in the myriad of KAI/Hinderer collabs that I have covered over the years. My particular XM has been given Rick’s “slicer” grind, which is his leaner more cutting oriented grind. Contrast this with his thicker reinforced “Spanto” grind. Even though this is the slicier of the two grinds, it’s still quite thick behind the edge and favors durability over raw slicing performance. I’m okay with that as it seems to suit the beefy, reinforced nature of the rest of the knife.

Hinderer offers their knives in a number of different blade finishes, and even a wharncliffe version now. Mine has been given a nice tumbled finish although you can also get them beadblasted, coated, or even hand ground by the man himself if you have the cash.

Over the years Hinderer has offered the XM in a proverbial cornucopia of different steels. The blade steel of this particular XM is S35VN which is probably what most of them are being made out of these days. S35VN is a good steel and has been adopted by Chris Reeve and Spyderco. The blade is heat treated to 60-61 HRc. This is a touch harder than what Chris Reeve has been heat treating his S35VN to, and the result is better edge retention, but it’s theoretically a little harder to sharpen. In use I have found that the edge stays keen, and I have only had to strop it to maintain sharpness. I haven’t had issues with rust, chipping, or anything else. No complaints here.

Handle, Ergonomics, and Pocket Clip

The handle of the XM is very well done. You have a G10 scale over titanium liner on one side, and then a full titanium frame lock on the other. Holding everything together is a bunch of custom hardware. This handle is beautifully made and you can really get to understand the quality of the XM by closely examining it. The parts are all overbuilt, but wonderfully finished. My titanium locking side has been completely stonewashed and this nice hard wearing finish compliments the blade nicely. It really is a beautifully made handle.

In hand the XM 18 is all business. Again, Rick designed this knife with firefighters and military in mind, and it’s a no-nonsense tool that works in a variety of grips. I have always been a fan of forward finger choils, and even without the choil there is plenty of room on this handle for large gloved hands. This is also a thick knife, and it really fills the hand. I can only imagine what the XM-24 is like. It’s probably akin to driving around in an S-Class Mercedes all day – solid and roomy. There is jimping on the spine, lock release, and pommel, but it’s wide soft jimping and doesn’t tear up your skin. I’d say the ergonomics are pretty solid with this one.

Hinderer equips the XM 18 with a reversible pocket clip. It’s not a deep carry clip and favors ease of access over concealment. It’s a big heavy knife, so you will feel the XM-18 in your pocket, but it carries alright for what it is. The clip sets into a recess in the handle so it’s a very sturdy design. I think it’s interesting that they include a “filler tab” for the clip mounting position you don’t use.

Deployment and Lockup

Hinderer offers these knives in flipper and non-flipper variants. Here of course I have the flipper version. Many view this as the knife that got the titanium frame lock flipper craze going, and the ZT0560 collab really brought that front and center to the masses.

What is sort of ironic about the XM-18 is that it’s not a particularly good flipper. Back when these first came out I am sure the flipping action was considered to be fine, but these days even my $30 Swindle out flips this knife. There are teflon washers inside and while I can pushbutton the blade open it isn’t a rocket launcher flipper by any stretch of the imagination. But that isn’t necessarily a kiss of death. This is still a very nice smooth knife with good action, and reliable deployment. You just need to decide whether you are looking for a really fast flipper or not. I will say the thumb studs work fine on this XM.

Lockup on this knife is the stuff of legends. The thick titanium lockbar engages early against the tang of the blade and there isn’t even a hint of play. The thumb studs double as blade stops and the stop pin is sleeved to avoid peening. There is zero stickiness to the lock despite not having a stainless steel lockbar insert. Also, lets not forget the inclusion of the Hinderer lockbar stabilizer. I’ve mentioned it in scores of other reviews, but this is where it all began. Lockup is just super duper good.

Hinderer XM-18 Review – Final Thoughts

Politics and price points aside, this is an impressive knife. I feel that there is a substantial bump up in beefiness and build quality when compared with a Strider or Chris Reeve offering, and it’s a big jump from Spydercos, Benchmades, and even new ZTs.

When I compare the XM to everything else I have reviewed before, I have to say that the XM is a different knife. It’s difficult to put into words, but it feels like every piece of this knife was first carefully contemplated, and then overbuilt and meticulously finished to a fanatical degree. This is an extremely solid knife and I am glad that I have finally been able to acquire one for long term testing.

That said, the 3.5″ XM-18 does have its potential draw backs. The fact that it’s heavy, and doesn’t flip very well are the biggest draw backs that come to mind.

This XM has been in my collection for several months now, and I’ve tried my best to approach the review cautiously given the enormous amount of hype built into these knives. While I can’t say I would spend $800 for one of these, I do think they are easily worth the $385 MSRP. At $550 I am less enthused, but still respect the knife for what it is. Like any other luxury good, some will love it while others will blast it as a ridiculous extravagance. Those that don’t like it can simply vote with their dollars and spend their money elsewhere.

Personally I view this as either a dedicated tool or a collectible. It’s not a daily carry item for me. But again, I don’t work as a first responder. I “need” this knife for work much like I “need” a Hummer to accomplish my 20 minute suburban commute every day. That said, I realize there are plenty of people who may actually need, or want, an over built knife like this. And if that’s the kind of knife you are looking for, Hinderer delivers in spades.

I can say without hesitation that the XM-18 is a beautiful knife, and I recommend checking one out if you are at all interested in it. I am glad I did.

LionSteel TiSpine Review

by Dan Jackson 7 Comments

Last Updated: July 27, 2019
Especially astute readers may note that I debuted a review of the LionSteel SR-1 a while back, and then published the world’s first review of the TM-1 not so long ago, but I conveniently skipped over the other folder in their SOLID lineup – the Ti-Spine. Rest assured it wasn’t because I wasn’t interested in the TiSpine. It was one of those instances of too many knives, too little time (or money… or both time and money). I am pleased to report that I have finally scrounged up both the time and the money to pen a review of this blade, and I am very excited to be able to do it.

Buy the LionSteel TiSpine at BladeHQ

Buy on Amazon

Oddly enough this almost delicate looking knife was designed by globe trotting gonzo reporter Robert Young Pelton, who is perhaps best known in the cutlery world for designing the hard wearing DPx HEST. Thankfully the bottle opener and wire strippers were left out of this model, allowing us to revel in the 4-axis machined goodness of this titanium beauty.

General Dimensions and Blade Details

The Ti-Spine has an overall length of 7.68″, a 3.35″ blade, and weighs 3.5 ounces. Out of the SR-1, TM-1, and TiSpine, the TiSpine is the most EDC friendly of the group. Although the blade is well shy of 3.5″, this knife still feels full sized, and I like how it doesn’t feel overweight. By way of comparison, I found the SR-1 a little ponderous in hand and pocket. The TiSpine is much more of a true EDC option for me. It would also make for a great special occasion / gent’s folder.

The drop point blade on the TiSpine is long and pointy, with a curving belly and potent tip. This classic blade shape has been treated to a high flat grind and swedge. The high flat grind will certainly cut stuff, although I have seen thinner grinds on other folders. My blade has been given a satin finish. It looks nice, although I do wish the transitions between the grinds were a little crisper.

LionSteel went with Elmax stainless steel for their blade material, and it’s a choice that I have seen pop up a few times on their blades. I have found Elmax to be a reliable choice for knife steel. It isn’t too difficult to sharpen, but it still has high hardness (here 59-60HRc) and holds an edge well. No problems with rust or corrosion either. A knife this pretty won’t get a lot of use in my collection, but it’s nice to know that they went with a quality steel.

Handle, Ergonomics, and Pocket Clip

Lets be real: most people will buy this knife for the handle. And what a handle it is. The 4-axis machined handle is so slick that it looks like it was cast from molten titanium. The way the handle catches the light and shimmers along its hundreds of grooves is tough for me to describe. It’s a gem of a handle. In this case, it has been further accentuated by a high polish and brilliant violet anodization.

Compared with the SR-1 it looks like LionSteel has further refined their manufacturing process. Being a monolithic handle, there isn’t much else in the way of hardware, but the pivot and stop pin are custom made and beautifully polished. The only downside to this pretty handle is that it picks up finger prints and scratches very easily. If you are looking for a “user” variant, I might suggest going with one of their less flashy matte finished options.

The handle of the TiSpine doesn’t just look good. This is also a comfortable knife. I doubt many will select the TiSpine for a month long trip to the amazon, or use it on a construction site, but this little knife feels good in hand and is capable of getting work done. I broke down boxes and opened mail without any issues. There is a short run of jimping which my thumb tended to pass over, and I found that I put most of my pressure directly on the rounded spine of the blade. Still, I was able to get a comfortable and secure grip on this knife.

The TiSpine features a long curving deep carry pocket clip. Mine has been given a bright polished finish to match the hardware and accentuate the almost jewelry like quality of the knife. This clip, while large, carries the knife discretely and I am not sure if many people would think you are carrying a pocket knife by looking at the clip alone. It is right side tip up only, but is completely removable if you want to and even more discrete option for carry. In pocket the TiSpine feels nice. It’s slim, flat, and relatively light weight. I had no problem carrying it.

Deployment and Lockup

The TiSpine makes use of an angular thumb hole for deployment. This low profile thumb hole looks great, and matches the sleek styling of the knife, but it is not particularly friendly for lefties. I had some trouble easily opening the blade with one hand, but I know that most people won’t have an issue. Inside there are teflon washers. The action is smooth and the tolerances are tight.

For lock up we have a sturdy titanium framelock. This is a nice titanium frame lock. My knife locks up early, and there is no blade play in any direction or lock stick. The monolithic construction makes for a super solid knife. Blade centering is a little off, but is no where near rubbing. I understand that is a common issue on both the TiSpine and the SR-1.

LionSteel TiSpine Review – Final Thoughts

I am sure many have fallen in love with the TiSpine at first sight. I know I did. I am pleased to report that the knife is even more impressive in person. This is a knife you need to handle to truly appreciate. The design is seductive and the craftsmanship is exceptional. I can find few faults with the TiSpine. I will say it’s not the most lefty-friendly knife. I’d prefer phosphor bronze washers and slightly crisper grinds. Beyond that it’s a beautiful knife and I wouldn’t change a thing. LionSteel has once again shown us that they are a company to be respected, and the sleek look of the TiSpine adds character and depth to their lineup of monolithic knives.

When contemplating the purchase of a TiSpine the real question is whether you are in the market for a high end collectible like this. It wont be to everyone’s taste, but if the TiSpine does appeal to you I definitely recommend it.

Chris Reeve Knives Sebenza 25 Review

by Dan Jackson 7 Comments

How do you improve on perfection? That may have been a question asked by the engineers at Chris Reeve when they approached the Sebenza 25. I wasn’t in the room, so I really have no idea. The Sebenza has received incremental improvements over the years, but for it’s 25th anniversary CRK really wanted to up the ante, or at least do something different from the tried and true Sebenza 21. The Sebenza 25 is that knife.

Buy the CRK Sebenza 25 at BladeHQ

The 25 is beefier and has more attitude than the 21, but there is still no mistaking it for a Sebenza. Is the 25 a worthy buy? Should you get it instead of a Sebenza 21? How does it compare with other knives in CRKs lineup? Having owned a Unumzaan, and presently owning a large Sebenza 21, I decided to pick up a Sebenza 25, give it a whirl, and attempt to answer some of these questions.

General Dimensions and Blade Details

The Sebenza 25 has an overall length of 8.375″, a 3.625″ blade, and it weighs 5.2 ounces. It’s similar in size to a large 21, but it’s definitely a more heavily built knife and weighs a full half ounce more. Offhand I would consider it as a hybrid between the 21 and the Umnumzaan. Unlike the 21, CRK does not currently offer a small version of the 25. Will we eventually see a mini 25? Only time will tell. I know plenty of people like to EDC the large 21, so I don’t see why you couldn’t EDC a 25. Personally I prefer a small Sebenza or a Mnandi for EDC, but I did make a point to carry the 25 around a bit to understand how it performs as a daily carry.

The blade of the 25 is a classic CRK drop point, with a few subtle (or not so subtle) changes over the 21. First of all the blade stock is visibly thicker at .14″ (which is approximately 3.5mm – the blade on the Sebenza 21 is about 3.1mm thick). Chris Reeve also gave the knife what they are calling a “large hollow grind” which is billed as a compromise between the thinness and slicing performance of a hollow grind and the toughness of a full flat grind.

I recently expanded my office at work and bought some new office equipment including a monitor, printer, computer, etc. As a result I had a lot of extra cardboard on my hands and decided to give the ole 25 a whirl at breaking down all of the boxes. I wasn’t blown away by the performance of the 25 on cardboard, but I wasn’t disappointed either. My large 21 slices a little better, but then again, so does my Benchmade Volli with it’s thin flat ground blade. It’s still miles ahead of the Strider SnG. The 25 is more heavily built than the 21, and it comes with a thicker grind. It’s not necessarily a bad thing, just different. Speaking of different, there is also a little depression in the blade after the jimping. I have no idea what it is for, so I’ll wait for someone to let me know in the comments section.

Steel on the 25 is S35VN, which is what CRK is using on pretty much everything these days if my understanding is correct. The blade on the 25 is heat treated to 58-59 HRc, and at that hardness it seems like a good combination of edge retention and sharpenability. Some might find it a little too soft, but I like a knife that easily takes a good edge, and the 25 has been very easy to maintain with my strop. I will say after testing the blade out thoroughly on cardboard the edge didn’t feel that sharp, but it still sliced paper with no problem. A few swipes on the strop brought it all the way back. If edge retention is super important for you, then you are probably better off finding something in M390 or S90V (harder more exotic steels), but if you are OK with the idea of regularly maintaining the edge of your knife then I don’t see a big problem with S35VN and this milder heat treat that CRK favors.

Handle, Ergonomics, and Pocket Clip

The handle of the 25 is the typical full titanium goodness you would expect from Chris Reeve. Construction is simple and elegant, with a pivot, stop pin, and single standoff. Some may lament the lack of a lanyard hole, but it looks like CRK designed it so you can loop some cord around the standoff. Personally, I don’t miss the lanyard doohickey on my large 21 at all. Construction is top notch, as expected. This is a Sebenza after all. I like the choice of beefier hardware. The pivot has seen a serious upgrade and the domed body screws are beefed up as well. The disadvantage to this setup is that 2 allen keys are required (and supplied), rather than just the one required to take down a standard Sebenza.

Perhaps the biggest change in the Sebenza 25 is the inclusion of double finger choils. It certainly adds a visual element to the knife not previously evident on CRK models. In practice I think the choils work well and capture the index and middle finger nicely. My hand feels very at home with the standard grip. A revision I am less enthused about is the razor wire inspired jimping installed on the back of the blade. I would say that the jimping on my large 21 is a damn near perfect blend of traction and comfort. Why Chris Reeve felt the need to mess with that winning formula is a mystery to me, but it certainly looks more aggressive. The jimping is fairly abrasive, but I only really noticed it on hard cuts, like cutting rope. Still I think they could have toned it down a bit. All said the 25 is a reasonably comfortable knife. I’m not sure I would call it an improvement over the 21, but it’s definitely different.

The pocket clip for the 25 is the same legendary double dip clip found on the 21. I’m glad they didn’t fool around with this. It works well and is one of my favorite clip designs. In pocket the 25 carries pretty good. It is a big knife, and is full titanium, but with that in mind I’d say it still carries well for its size.

Deployment and Lockup

The term “Sebenza smooth” is something of a gold standard in knife collector circles when considering the action of a pocket knife. So it’s interesting to see that CRK made some tweaks to ensure the deployment of the 25 is even smoother than its predecessors. In addition to a much larger pivot, the knife features extra large perforated phosphor bronze washers. According to the Chris Reeve website these were installed to carry more grease and make the action smoother. In practice I think it has worked. My 25 is noticeably smoother than my 21. Granted I am testing a pretty small sample size here, and some may disagree because the 25 doesn’t include the 21’s famous bushing pivot system.

The knife flicks open easily via the ambidextrous titanium thumb studs. Speaking of thumb studs, or thumb “lugs” as CRK calls them, I think it’s about damn time that dual thumb studs came standard equipment on a Sebenza. I also can’t help but wonder if CRK has plans to introduce a bearing equipped knife in the future. Bearings are by no means a necessity, but since that is where a lot of the industry is going I would be curious to see them offer a knife with bearings.

For lock up Chris Reeve went with a ceramic ball detent. Just like on the Umnumzaan, it serves double duty as both an interface between lock and tang, as well as detent to hold the blade in place. It works well and I have no complaints. The blade locks open with a satisfying thunk and lockup is steady at right around 50%. No blade play at all and the blade is perfectly centered.

CRK Sebenza 25 Review – Final Thoughts

For whatever reason I always find myself under some pressure to come up with a poignant parting thought on Chris Reeve products. Perhaps it’s to justify the price in my own mind, or justify the level of excitement and expectation that has been built up around these knives, or attempt to get ahead of the inevitable discussion about Chris Reeve knives and “value”. I’m going to avoid that this time around, and instead focus on my honest take on the knife.

I think the 25 is a solid and well made product. I consider it a hybrid between the Umnumzaan and 21. That’s not necessarily a bad thing, but if you already have a 21 or an Umnumzaan I don’t really see the “need” for this knife. Then again, I don’t really see the “need” for a $450 pocket knife in general, yet I have owned dozens, so that is beside the point. Like other high end knives, people will buy this because they want it. I’m here to tell you that if you want it, it’s a nice knife. But I’ll also play the role of devil’s advocate:

The 25 is thoughtfully designed and well made, but isn’t a huge enough leap from Chris Reeve’s other offerings for me to truly get excited over it. Maybe if they installed bearings, milled the handle from a single piece of titanium, or did a flipper or something like that it might move the Richter scale a bit further. Don’t get me wrong, it’s a perfectly fine knife, and if this is your first CRK I think you will like it, but when you compare it with the rest of the CRK product line I can’t help but feel like it’s more of what we have already seen. I’m glad I got to check one out, and recommend you to do the same if the 25 interests you, but I don’t feel compelled to hang onto both the 25 and my large 21 or to tell you that this is the most amazing thing since the titanium frame lock.

Zero Tolerance 0801 Review

by Dan Jackson 7 Comments

Last Updated: August 7, 2019
Titanium framelock flippers. Are we sick of them yet? No? Great, because I’ve got another titanium framelock flipper review for you today. Given the rapid influx of titanium framelock flippers on the market, I initially thought that I would pass on the Zero Tolerance 0801. The wide shape, chunky build, and monochromatic look of the knife all lead me to quickly dismiss the knife.

Buy the Zero Tolerance 0801 at BladeHQ

Buy on Amazon

It wasn’t until I handled the 0801 in person that I decided to buy the it. Oddly enough, I became so intrigued that I ended up acquiring 2 of these at once – the standard version, as well as the 0801CF “Copperhead” limited release version of it. This review will focus on the 0801, as the 0801CF is a true collectible that I ended up selling off and never using.

Designed by acclaimed custom maker, Todd Rexford, this understated design is based off of his Singularity custom offering. The 801 is the second in a string of collaborations Todd has done with KAI (the previously reviewed Kershaw Injection being the first). This is his first high end collaboration with Zero Tolerance.

General Dimensions and Blade Details

The 0801 has an overall length of 8.2″, a 3.5″ blade, and weighs 5.85 ounces. The 0801 is a substantial knife and you will feel it in your pocket. It isn’t quite as chunky as the 0550, but it’s pretty darn close. No doubt that is due in part to the thick full titanium handle. I can’t think of any other production full titanium flippers on the market at the moment, so that is something to keep in mind. I like the fact that ZT has introduced a full TI handle into their lineup. Just understand that the 0801 ain’t no feather.

The blade on the 0801 is a spearpoint shape with a high flat grind. There is also a swedge that terminates well before the point to support the tip. The blade shape, like the rest of the knife, is pretty sober looking. But it certainly functions well in normal cutting tasks like breaking down cardboard boxes, doing light wood processing, and other general utility tasks. The blade is pretty thin behind the edge and the knife comes very sharp. It’s nice to see a high performance grind on this kind of knife, as the ZT/Hinderer collabs seem to favor strength over slicing.

The 0801 comes in Elmax steel. Elmax has become a staple in Zero Tolerance’s higher end line up. I have come to enjoy Elmax for its combination of good edge retention and relative ease of sharpening. I have had zero issues with rust or corrosion. I think Elmax is a good choice in this higher end offering.

Handle, Ergonomics, and Pocket Clip

The 0801’s full titanium handle slabs are separated by three black standoffs. This knife has been well executed. There are no visible machining marks, all the parts line up well, and everything has been nicely finished. The oversized decorative pivot is a nice detail, and the black hardware serves as the only contrast on the knife. The handle slabs themselves have been milled out with grooves and has a sort of sweeping faux bolster look. I am not wild and crazy about the grooves or the “ZERO TOLERANCE” brand engraved into the handle, but I have to admit Jim Skelton’s customized version with blue two-tone anodizing job really pops.

The 0801 works fine from an ergonomic standpoint. I wear a large glove and there is just enough room for a 4 finger grip – those with freakishly large hands may run out of real estate. There is something of a forward choil, so you can choke up and get a little more out of the handle if you need to, or lay back for more powerful cuts. There isn’t any jimping on this one, so you don’t have to worry about hot spots for your thumb, but I readily acknowledge that the absence of jimping may be a turn off for some. The rest of the handle feels good. This isn’t a funky handle shape so it should work well for most people.

The pocket clip on the 0801 is straight out of the KAI parts bin. A slightly smaller version of the clip can be found on the Cryo. Visually it’s not the most amazing clip, but it is very practical, especially if you are into deep carry. The 0801 buries into the pocket, but even if your co-workers won’t notice it, you certainly will. At near 6 ounces this is not a lightweight pocket knife. That’s the trade off when you go for a thick full titanium handle. It would be cool to see ZT pocket out the inside to lighten things up, but I know that is probably cost prohibitive. If you are into bigger, heavier knives this obviously won’t be an issue, but weight weenies need not apply.

Deployment and Lockup

As far as titanium framelock flippers go, the 0801 is up there with the best on the market. I’m not saying it’s as good as the freakishly fast 0454… it’s definitely nothing near that, but fans of snappy flippers should still be satisfied with this knife. The Elmax blade rides on KAI’s KVT captured bearing system, and you can see the guts of it peeking out by the lock face. I thin it is somewhat unseemly to have the bearing cage poke out like that, but I guess that is what needed to be done to make the knife work right. All said, fans of flippers will find a lot to like with the action of the 0801.

ZT incorporated a stainless steel lockbar insert into their frame lock, and the steel on steel contact makes for a secure and stick free engagement. I couldn’t detect any sort of blade play. The lock geometry of this knife has definitely been dialed in, and the blade centering is perfect. These details are important to find in this higher end knife.

Zero Tolerance 801 Review – Final Thoughts

There isn’t anything else out there filling the full titanium framelock flipper niche, so off the bat that puts the 0801 into a league of its own, unless of course you are willing to venture into custom, midtech, or aftermarket territory. The full titanium handle does have its potential drawbacks, mainly the weight, but there are plenty of people willing to forgo an ounce or two for full TI goodness.

Despite not having any direct competition, the 0801 doesn’t rest on its laurels. It is a very solid and well made knife. Build quality and materials are both excellent. The flipping action and lock up are superb. The design is austere and based off of Todd’s coveted custom offering. There is a lot to like here for fans of high end production knives and frame lock flippers. If you are interested in the 0801 I can safely recommend it.

Fantoni CUT Flipper Review

by Dan Jackson Leave a Comment

Last Updated: August 30, 2019
We are in the midst of another Italian Renaissance. This time around it’s not a blossoming of politics and art, but of steel and titanium. The Italians are making some absolutely beautiful knives, and I can think of few examples that typify this as much as as the Fantoni CUT Flipper. At its core the CUT Flipper is a meat and potatoes knife. It is sturdy and well made, unpretentious, and intended for real use. Yet this knife has been elevated. The elegant design coupled with a fanatical attention to detail lifts the CUT Flipper from object to art.

Buy the CUT Flipper at KnifeArt

The CUT Flipper has been on my radar for several years. Carried by boutique purveyors and retailing for around $400.00, the CUT Flipper has eluded my grasp for some time. This is a collaboration between Fantoni and Dmitry Sinkevich, the same designer who brought us such things as the Zero Tolerance 0454 and many Shirogorov designs. The problem with the ZT 0454 and Shirogorov flippers is that you can hardly find them, let alone find them for a reasonable price. The CUT Flipper, while no means widely circulated, can still be found at retail (at least at the time of this article and for the past few years – Fantoni has never been known for high production volume). That places the CUT Flipper at a unique spot in the marketplace, and practically begs for a closer examination.

General Dimensions and Blade Details

The CUT Flipper has an overall length of 3.5″, has a 8.375″ blade, and weighs 5.3 ounces. This a larger knife meant for work. Some might call it a tactical knife. It’s obviously too big of a knife to carry around in an office setting, but it works fine with jeans and could certainly be an EDC item if you like carrying larger knives. There isn’t anything wrong with viewing this as a collectible either.

The blade shape of the CUT Flipper is an upswept modified drop point. I really love this blade shape, and I think it is part of the reason why I gave the Kershaw Turbulence such high marks. You have a high flat grind, swedge, and a neatly applied edge. The finish on this knife is very nice. It’s a high polish with a stonewash over it (or maybe a stonewash that was then high polished – hard to tell really). Regardless the blade has a deep luster that looks great and hides wear. It’s also a low friction finish, and it helps the blade slide through material.

Fantoni went with tried and true CPM S30V for their blade material. I have no complaints with the steel selection. I’ve had some issues with S30V in the past, but done right S30V is a proven steel. Here Fantoni has heat treated the blade to 60-61 HRc, and the knife takes a nice working edge that touches up easily on a strop or my ceramic rods. The CUT Flipper isn’t super thin behind the edge, but it thins out enough to be a capable slicer. It’s a good compromise between strength and agility. The upswept tip is strong, but the steep angle means that it isn’t my first choice for clipping coupons or other fine tip work. All in all, the blade lives up to its namesake, and it performs if you are looking to put the CUT Flipper to work.

As an aside, I know that Renzo Fantoni, the founder of Fantoni Knives, is a big fan of super steels. Don’t be surprised if Fantoni ends up producing a limited run these in S125V or some other insane steel.

Handle, Ergonomics and Pocket Clip

The handle of the CUT Flipper has a lot of really nice details – there is lot for a collector to admire here. 3-D machined slabs of G10 rest atop thick cut pieces of sandblasted titanium. All of the edges have been painstakingly radiused. At the end of the day construction appears simple, but that is only because they have pulled it off so flawlessly. I love the oversized hardware and how the backspacer was finished and slots around a lanyard pin. I’ll try to do my best with the pictures, but you really need to examine one of these in person to get a true feel for the workmanship.

In hand the CUT Flipper feels fantastic. It’s a larger knife and the handle is pretty thick, so those two factors add to this, but the slight pistol grip to the handle shape leave great spots for your palm and thumb. There is a a run of mild jimping that looks nice and serves its purpose, while the rest of the knife is devoid of aggressive texture. This knife feels natural in the hand and I had no problem breaking down boxes and carving up 2x2s with this.

The pocket clip is a simple bent titanium clip, and is given the same sandblast as the liners and laser engraved with Fantoni’s subdued logo. This is a small detail, but I like the choice of domed pocket clip screws – even they seem to be of very high quality. It is a sturdy clip that holds the knife steady, and reasonably low in the pocket. The handle is tapped for ambidextrous tip up carry, a nice nod to this knife’s utilitarian roots. At 5.3 ounces, the CUT Flipper is definitely something that you will notice in your pocket, but I don’t think the weight or the way the CUT carries is unreasonable given the size and construction of the knife.

Deployment and Lockup

The CUT Flipper is obviously a flipper style knife. If you prefer a non-flipper variant, check out the aptly named CUT. The flipping action on this knife is not something to write home about. You need to pushbutton (preload) the flipper to ensure a speedy and complete deployment, and that is a mild let down for such an otherwise fantastic knife. Still, the CUT Flipper is quite smooth and I still enjoy opening and closing it ceaselessly, periodically pausing to admire the blade or the gentle play of titanium and G10.

The CUT Flipper is a liner lock. The generous titanium liner engages fully and the blade locks up solidly and without play. It looks like Fantoni may have heat treated or carbidized the lock face, as there is slight discoloration in the last quarter inch of the liner lock – right where it meets with the tang of the blade. Performance of the liner lock is excellent and the blade centering is dead center.

Here is a shot of the CUT Flipper next to my Strider SnG:

Fantoni CUT Flipper Review – Final Thoughts

I can think of few folding tactical knives that have that holy trinity of form, function, and uber tight finish work. Some may argue that the “holy trinity” is just that: the Chris Reeve Sebenza, the Strider SnG, and the Rick Hinderer XM-18. Having owned two out of the three and handled several XM-18’s, I think the CUT Flipper belongs right next to these standard bearer blades. The CUT Flipper may not have the track record (or the marketing effort) of these other knives, but it certainly has the design chops, build quality, and functionality of these other knives.

This is a knife I have been drooling over for some time. Sometimes when that is the case I get a little underwhelmed when the actual knife arrives. Not so with the CUT Flipper. I think I actually like the knife more now that I have it. The CUT Flipper hangs with the best of them and has earned my wholehearted approval and recommendation. If you are at all on the fence about this knife, my suggestion would be to buy it with confidence. You will not be disappointed.

I would recommend buying the CUT Flipper at KnifeArt, as they are Fantoni’s only US dealer. However, their stock is limited.

I would also recommend purchasing the CUT Flipper at Amazon or BladeHQ, however, neither retailer seems to carry Fantoni Knives. Regardless, please consider that purchasing anything through any of the links on this website helps support BladeReviews.com, and keeps the site going. Thank you very much.
