Review:Dmitry Sinkevich Zero Tolerence Design 0456

Most of the readers know I really like ZT knives. This new ZT is a beauty of a design from a collaboration between ZT and Dimitri Sinkevich a noted Belorussian knife maker. This new knife known simply as the 0456 has Titanium handles with blue aluminum accents and pocket clip. The blade opens with the KVT ball bearing system ZT uses on many of their knives.


The blade itself is CTS-204P steel which stands up to a lot of wear and resist corrosion well. CTS-204P is a knife steel with a significant carbon content which aids in the strength of the blade and it’s cutting power. The blade shape is very strong and has a bit thicker blade than is usual for this size knife. The blade is the same design found on Dimitri’s custom knife named “The Pole”.


The flipper is large and makes the blade very easy and fast to open. This blade came from the factory with a good edge on it and that edge held up well through a fair amount of cutting over several weeks. After those few weeks of use I used a natural Japanese stone to bring the edge back to shaving arm hair sharp. It really didn’t take a lot to get there.This is a good size daily carry knife and with the ease of opening wouldn’t make a bad defensive tool.

From ZT Knives

Zero Tolerance and Belarusian custom knife maker Dmitry Sinkevich have teamed up to produce the 0456. The 0456 offers the premium cutting power for which ZT is well known in a knife with standout looks that are just waiting to be shown off.

Based on Dimitry’s popular custom knife, The Pole, the 0456 features the 3-D rayed handle contours and custom blade shape that defined the original design. The high-quality CTS-204P blade steel is wear and corrosion resistant and takes an exceptional edge. The blade’s premium quality is matched only by its good looks—with an appealing two-tone finish that’s stonewashed on the flats and satin on the grinds. The 0456 opens with ZT’s KVT ball-bearing system for a quick, easy blade release. A titanium frame lock, with a hardened steel lockbar insert, firmly secures the blade open during use.

The 0456 deftly balances handsome appearance and solid utility. On the appearance side, the pivot hardware, custom aluminum backspacer, and left/right reversible pocketclip are finished in a brilliant blue. On the utility side, the 0456 offers top cutting capabilities and excellent edge-holding performance making it the perfect tool to take along with you on any bold adventure.

  • Threethreeight

    Can we try to get the photos in focus? Maybe stopped down a bit?

    • Pete – TFB Writer

      The look great for me.

    • I try to please but I’m not sure what else I could do to make them sharper.

      • Threethreeight

        If you’re using a phone, just back up a bit. they don’t handle macro especially well. You can crop them down later. All the shots are composed well, for what it’s worth.

        • No I’m using an Olympus OMD-5 with the 12-40mm PRO lens. I do sometimes use my IPhone 6S with a set of Auxley lens one of which is a macro lens. They work surprisingly well!
          I know if I took the photos inside under lighting I could use the lights and a tripod and get great shots but I just prefer to take my gun, knife and other gear photos in natural outdoor light.

          Thanks I try to compose them in a pleasing way.

          • Threethreeight

            In that case, manual focus in aperture priority and play with the aperture size for cool depth of field stuff. Maybe consider a macro lens if you’ve got the spare cash laying around. You can get a pretty cheap tripod from Amazon that’s 55-60″ for like $25.

            At any rate, I look forward to more of your content ?

          • I have a good tripod but it happens that the wife had the car it was in when I needed to get these taken. I’m actually saving for another Olympus lens ZUIKO LENS ED 50MM F2.0 MACRO 1:2

  • Pete – TFB Writer

    Beautiful knife. Thanks Phil.

  • Scott Tuttle

    I dont like the blue clip but the rest of it is nicey nice. make the clip black I think.

  • Scott Tuttle

    cam’s autofocus prob had trouble with that brushed metal

    • This time it was set on auto with auto ISO settings. I usually set the camera on good old P and set the ISO manually.

      • Jake

        Gotcha. IT’s most likely having trouble with the auto focus lock, when I’m lazy, I’ll use something that’s the same height to get the auto focus lock, then just swap the gun part. Mainly used legos for that, heh.

    • Jake

      A good trick I do when I’m doing ‘quick’ macro shots is to use something as a stand in to get the AF lock and then swap in the actual knife / gun part.

  • Will

    What, exactly, makes this knife worth $300.00?

    • Partly Titanium and material cost plus whatever the cost of being able to make Dimitri’s design not to mention it’s a darn good knife.
      ZT doesn’t make cheap knives they are made very well as most owners would attest to.

    • Devil_Doc

      A quality knife will be in use by your grandkids long after you’re gone. Try that with a $30 made in China Kershaw…

      • You hit the nail on the head! ZT knives are made in the USA also which makes it more expensive but these things are built like a tank.

      • Giolli Joker

        Curious choice… ZT is part of Kershaw (KAI).
        And several Kershaws are made in USA.
        ZTs are usually cool, designed by famed knifemakers and realized with top materials… however their frame locks have shown more than once limited locking strength.

        • Devil_Doc

          Lol.. Coincidence. I carry a cheap $30 made in China Kershaw. When I break it or lose it, i’ll just buy another.

      • Treyh007

        ZT is Kershaw…… Just of better quality!

  • I know the MSRP may seem a little on the high side but as I mentioned to another reader they use great materials such as the Titanium handles and ball bearing system. I’m also not sure how much it cost to purchase the rights to make Dimitri’s design.
    This knife should last a lifetime I would imagine. Most of the owners of these higher quality fairly limited edition knives are glad they took the plunge and end up owning several of them myself included. With a knife you really do get what you pay for. Just my opinion from years of collecting and using these knives and other fixed blade knives.

  • The handle is made of Titanium—-

    • Wanderlust

      yeah, i was talking about the blade, I probably should have said blade after the first line. as for the value im not saying its not a good overall value, just that its not a discounted product, its in line with other products like this.

      • Ok gotcha and I always use the MSRP. I did look around after reading your comment and found one for $245.

        • Wanderlust

          One interesting thing about the knife world in relation to the firearms world is its a lot easier to find the materials one is paying for. It would be nice if the barrel steels, and frame materials on many guns were as thoroughly categorized.

  • Chris laliberte

    Someone please help me understand why these really nice, very expensive knives use liner or frame locks. Isn’t one-handed closing under stress important? I Just can’t get comfortable with exposing my thumb to the blade closing on it, in order to close the knife to put it away. Axis lock seems so much better, so I’m sure I’m missing something, please clue me in (and don’t flame me too hard, I’m genuinely trying to appreciate these fine knives).

    • I never considered being able to close one quickly under stress an important feature. My main concern was being able to get it open quickly if ,heaven forbid, I needed to.

    • Madcap_Magician

      I think the patent on the Axis lock is still in effect, so until that expires, Benchmade will be the only ones making legal Axis lock designs.

    • raz-0

      Because back in the 90s, it was different than a back lock, and everyone either didn’t care about IP or it was unencumbered by patents. So liner locks got pushed as the cool thing.

      I bought into it. Kind of questioned it when I got my first poorly QCed one, and outright dislike them after having some expensive ones becoming less reliable over time and use. I avoid them like the plague now.

      IMO the need to close something rapidly under stress is completely non-existent. Close it while encumbered? Sometimes needed, and doable with care with most knives. It’s not how they behave when being closed intentionally that I dislike, it’s
      the unintentional deactivation of them. As they get cycled, I find that it gets easier and easier to disengage the lock with a strong grip on a lot of liner locks. Frame locks are a bot better, but I still find that to get a knife that feels good opening and closing and locks up seems to reduce the acceptable tolerances on a part that is going to wear over time. It doesn’t help that you are making a spring out of metal not meant to be a spring.

      I think knife makers like them because there is very little needed design wise to accommodate them, so you get to indulge things that look cool and blade shape and whatnot without having to go into engineering something and adding bits to the knife. So you can dream something up without thought to how it works, focus on the looks, and retrofit it easily without changing the look very much. I could be wrong.

      I’ve been slowly building up my collection around various locking mechanisms, and I have to say the bolt action, ball bearing, axis, arc, etc. style of locks are some of my favorites for all around function. liner/frame locks are really some of my least favorite this side of practical. I have a ton of things that are not remotely practical

      • Chris laliberte

        Thanks for the thoughts, makes a lot of sense in that historical perspective, and also the simplicity of design not needing to accomodate the more complex internal features of the axis-type locking mechanism. I’m surprised people don’t value safe one-handed closing much. It’s kind of like flagging yourself re-holstering–unlikely that you’ll hurt yourself, but it just feels wrong to have that thumb in line with the now-unlocked blade as it starts to come back into the handle. I stow my knife encumbered all the time, generally holding something with my other hand that I can’t or don’t want to release, and sometimes that can be a “stress” situation even if it’s just setting a tarpline. Again with the holstering comparison, it’s like having a rigid holster vs. a soft one that doesn’t stay open on it’s own. Not an issue when you are calm and have time, but when you really need to re-holster one handed / encumbered, makes all the difference.

  • john huscio

    I like Dimitri’s designs…..I’d be down for one……when I can find one for half price on eBay ……….right now in more into concealable fixed blades like the spyderco street beat or Spartan Enyo/Phrike.

  • Will

    I have to admit it is a great looking knife, no doubt about that. But MSPR of $300.00? That’s pretty steep for my wallet.
    I’ve carried a Kershw Beawler for well over a decade and it has served me well but I don’t use it as an all purpose tool. I’m very picky about what I cut with it and do not abuse it.
    Maybe if I hit the lottery I’ll get one of these.

  • Madcap_Magician

    CTS 204P more or less is the same thing as M390 more or less is the same thing as Duratech 20CV.

  • What a beautiful knife. It’s a bit pricey, but will definitely go on my bucket list. It’s rare to see a blade that matches form an function so well and can still be easily carried in a pocket. The quick-action opening and easy folding closed are also huge selling points, in my opinion.
