Another Excellent ZT Knife (with a few new surprises!)
Christopher W.
This knife is not only a larger version of the 0460, but the latest version of the ZT-Dimitry Sinkevich knives with new features. In size, it is closer to the larger Polutchetkiy Sinkevich custom knife. The action is excellent and, as part of the new features, ZT has removed the ZT logo from the presentation side of the knife and put it on the inside of the Ti scale of the knife. It is a true, worthy sibling of the excellent 0452CF knife as well.

The remainder of the branding on the knife is on the reverse side of the blade. The blade itself has a very long cutting edge and is slightly upswept, forming a very nice integral line with the handle; the CPM 20CV (M390 is Bohler's version and vice versa) blade has been in use for me for a month and has yet to require any sharpening. The grind is very even and I estimate it at 18 degrees from factory (the usual range is 18-22 degrees for most newer ZT knives). Because it is a CPM alloy, it can sustain an even lower angle without problems. Regular stropping, as always, seems to help and retains the sharpness of the blade; there are no uneven portions along the edge bevel. The machine satin finish is incredibly even and consistent all along the length of the blade. The grind appears to be a compound Hamaguri/Appleseed type. I find that it is an extremely robust cutting edge and any form of micro-rolling can be taken out by stropping. It does not appear to be vulnerable to chipping.

It came hair-poppingly sharp out of the ZT box. The handle itself is also extremely comfortable and accommodates all four grip styles without the need for jimping or choils at all; this is a *very* well designed knife from not only the point of view of handling, but also looks and everyday carry utility.

The pocket clip is low profile and does not cause any hotspots when held in any grip configuration. Being a lower profile clip without a very aggressive ramp, it requires a one-handed technique for double-thickness denim pockets; simply form a V with your index and forefinger around it and insert it snugged up towards the seam (front or back) of the pocket firmly. You can also lift up the tip with your middle finger. I find that even for most jeans, this is not required on anything but the thickest doubled-up denim material.

The action is mind-blowingly good and smooth; both for flipping open and for dropping shut closed. It requires a dry break-in period, fresh out of the box, of about half a day and then another day lubricated. It will continue to become better after this, as the KVT bearings wear and bed into the race washers and the detent ball forms a surface wear-track (which is also beneficial for lubrication).

The action on this is the same, if not better, than very many custom knives that are priced an order of magnitude higher. The classic ZT explosive, reliable, and dependable launching action is there. No matter how gently you flip it, it will always proceed to lock-up successfully. The detent is excellent and firm; in addition to not being able to be shaken out, it ensures that whenever the blade breaks free, it will be at the acceleration required for positive lock-up.

The KVT bearings used on the 0462 are the original brass ones, as compared to the blue ones on the aforementioned 0452CF; there are custom MRBS-style bearings available for this as well as the other ZT knives, bringing it one step closer to being a production version of the Sinkevich/Shirogorov Polutchetkiy. As stated before, once broken in, the action is capable of dropping shut one-handed from the vertical after the lockbar has been disengaged with your thumb.

Revisiting the blade, once extended the lock-up is, as is the case for all ZT knives, extremely solid. There is simply no flex at all left to right or up and down, let alone blade play. The tolerances are, true to the name, effectively zero. The flipper tab is, due to the curve of the handle, very out of the way in the pocket.

Both a lightswitch and sliding action will actuate it; if you want to use a push-button style, you must use it by toggling the distal joint on your index finger much like a toggle lock. This is because the flipper tab itself is ahead of the pivot; but once you toggle it in this fashion, it gives you the advantage of a large amount of acceleration.

Lock-up is tight out of the box at 5%-10%; after some period of break-in by actuating it and adding some lubricant, it will settle to a 15%-25% lock-up. There is no lock-stick under any conditions. Even under the slowest lock up, tested by slowly moving the blade to full extension manually, the lockbar will positively engage and lock up. I have not experienced any "partial" lock up. It really does aggressively lock up if the blade is nearly extended. Moving the lockbar out of the way is smooth and there is no shift of the blade until you either use your other hand, tip it with your index finger, or finally remove your thumb and let it drop shut.

The handle of the knife is a beautiful combination of a full slab of black/red CF/Kevlar weave on the presentation side and stonewashed Ti on the reverse/lockbar side. This is a deeper, more vivid red than the copper featured on the 0460; in incident sunlight, it really lights up and contrasts with the black CF. The black aluminum backspacer is raised from the general curve of the knife a little bit and has some jimping; this increases the level of comfort when gripping the knife and is probably the reason they designed it with a full back-spacer rather than just the back-spacer standoffs on the 0452CF. If you are more a fan of an all-black knife, there is currently a sprint version of the 0462, the 0462BLK, that is all black; this includes the hardware and the blade (S35VN on the sprint run).

The rest of the hardware on the knife is of exellent quality. A Torx T8/T9 (both will fit well) is used for the captured pivot (indexed on the presentation side with a rectangular boss that engages with a keyed rectangular cutout in the CF side); the rearmost screw is also a T8/T9 and consists of a barrel screw and a regular screw. The keystone screw that secures the top of the backspacer to both of the handle scales is a Torx T6, as are the two clip screws.

Centering came just about perfect with this knife, but there is more to it than just that; when you take apart and put the knife back together, there are several things that you can use to tell you that you got everything back just the right way. Like the 0452CF, 0450CF, and 0460, the 0462 will stand upright on the scales if placed down on a flat surface vertically; this plays a role in the centering of the blade within the handle as well as the action. Once you have put the knife back together, place it on a surface you know is flat and ensure that all four contact points are flush and the knife sits level. Tighten the pivot first, while maintaining even and flush contact with the flat surface; next, proceed to the keystone screw and the back screw and tighten them in an alternating fashion, ensuring that the knife remains flush standing on the flat surface. Done properly and correctly, the result should be a blade that is 99% centered; the remainder of the centering should be *very slight* tightening/untightening of the pivot screw and it should be very sensitive to the tension applied by the pivot screw at this point. When 100% centering has been obtained, the action will be at its fastest and smoothest automatically.

The interior of the Ti scale is milled out for weight reduction, but the pattern is very interesting; my engineering theory is that the specific pattern they used imparts a unique strain response in the Ti scale, which results in the aforementioned behavior. It is not merely cranking down on the pivot screw to try and change the action or centering, but a balance between all three screws and the scales that automatically does it. This is different from quite a few other folding knives I have tried and provides a very large range of tuning potential to fine tune it to the user's taste.

There is another secret feature, or at least I think it is, on the blade itself. When closed, and viewing down through the front of the scales, you notice that there is a small trench that is in the middle of a larger valley in the root of the blade tang. At first, I believed this was some type of stress relief feature or required during production. Neither of threse make sense since the CPM 20CV blade is laser cut out of the stock sheet and the trench has a far sharper radius of curvature.

Then I tried an experiment, I took some SuperLube (85W), and dropped it straight down onto the trench. Partly expecting and partly being surprised, the surface tension of the lubricant droplet sitting within the valley broke, and it proceeded to flow down evenly along both sides of the blade tang root and into the bearings. Keeping the knife held vertically for a little while longer, the lube made it to the detent ball, detent dimple, and the track that the detent ball runs along when open. I have tested this numerous times and compared it to lubricating the conventional way by opening up the knife. It provides exactly identical results with the same, or less, lubricant used. It will work with 5W, 85W, and 100W viscosity lubricant. Without the trench in the valley, the surface tension would have otherwise kept the drop there and it would not have been able to flow down into the small gap to coat either set of bearings. This is an *excellent* feature and it means you no longer have to take apart the knife to lubricate it. I do not know if ZT or Sinkevich was responsible for this feature, but it is not something I have seen on any other folding knife; even other ZTs.

This knife is a culmination of ZT listening to user feedback and making changes to details from their previous, and also wildly successful, collaborations with Dimitry Sinkevich. The looks, design, and overall flow of the lines of the knife are very attractive and the knife itself receives compliments in public since it is my everyday EDC knife. It has proven itself for use at home, in the office, and in the outdoors (I am an avid climber, hiker, and photographer). I would very highly recommend this knife for its combination of elegant and attractive looks, super-steel blade, utility, engineering, and everyday usability. This continues ZT's excellent reputation of knives built like tanks; only now they are adding on the beautiful and fast looks of fighter jets too.
Brandon R.
This knife is just as spectacular as the original 0460 , but just in a larger package. The red carbon fiber scale is an awesome touch with the satin finish blade. Very lightweight for the size , and hides in the pocket nicely.
Great knife
Chris S.
I got the all black version if this and I absolutely LOVE it!!! This was my first ZT purchase and it will not be the last. The knife is on the bigger side but it's very thin and slender and also very, very light for the size, so it is not bad at all to carry.
Light and smooth
Anthony B.
ZT and Sinkevich succeed again with this sexy beast. Not too big, incredibly smooth, deceptively light, the curve makes it disappear in pocket. One of the best in this price range.
What a blade!
Eric A.
This knifeís unique look does not stop it from being extremely comfortable in the hand. The blade is stunning and the flipper action is incredibly smooth. Though it is quite long overall, itís ergonomics and light weight still make it practical to carry everyday.
Just stunning.
Kevin T.
Got this knife a few months ago and it is just beautiful! Zero tolerance machining and quality control are just amazing. Ball bearing action is smooth as butter and I can't stop looking at the carbon fiber handle! Love this knife!
My favorite ZT knife.
Darren R.
While I have owned at least 10 different ZT models (and still have mist of them), this one is my favorite. Not only does the curve of the handle give my medium sized hand a very comfortable and secure grip, but the red tinted carbon fiber provides a beautiful and distinctive appearancej. Likewise, while I personally love the thin curved lines of the persian style blade, the ultra premium 20cv steel choice means you will definitely get a long life out of it as well. Finally, despite its large size, the knife feels extremely light and is barely noticeable in the pocket, and the fit and finish is absolutely perfect. Overall, assuming its style fits your preference, this knife is a great choice.
