Zero Tolerance ZT 0462 is a designer knife for everyday use , equipped with a CPM-20CV steel blade , titanium and carbon fiber cladding and KVT bearing support. The design of the ZT 0462 is inspired by Dmitry Sinkevich's custom knife - Polychotky Jr., which attracted attention with its slender, upward-curved blade and ergonomic handle with an arched profile. Premium grade steel The 83 mm long blade is made of CPM-S20V powder steel hardened to a hardness of 59-61 HRC . CPM-S20V is an American "super steel" whose parameters correspond to the elite stainless steel Bohler M390. Thanks to the high content of chromium and a large amount of vanadium carbides, the steel is characterized by exceptionally good resistance to corrosion and wear, and a very long retention of sharpness. When choosing a knife made of such steel, it is worth getting a diamond sharpener, because sharpening using a standard ceramic whetstone can be very laborious and ineffective. Original blade The slim blade with a trailing point profile has an elegant satin finish. Thanks to the strongly marked curvature of the blade and the use of a flat grind, the knife has outstanding cutting properties. The point, despite being located above the ridge line, provides excellent penetration. The thickness of the blade at its widest point is 3 mm, which is a compromise between the durability and functionality of the knife in everyday work. Comfort of use The blade is unfolded with one hand using a milled flipper, a solution convenient for both right and left-handed users. KVT ball bearings are installed on the axis of the blade , thanks to which the blade works smoothly and lightly when unfolding. Work safety Against accidental folding of the blade, the titanium frame-lock is effectively protected by a hardened steel insert that prevents abrasion of the titanium. Frame-lock is a solid lock considered to be one of the most durable locking mechanisms, characterized by resistance to dirt and very comfortable operation. Ultralight handle The knife has ergonomic handles made of brown and black carbon fiber and sandblasted titanium . The curved profile claddings characteristic of this model (raised up) are in a way a counter to the blade with a clearly convex belly. On the edges of the titanium linings, diagonal milling was machined, improving the grip and giving it an elegant look. All edges have been perfectly finished, emphasizing the high class of the knife. The protruding spacer insert has transverse ribs, improving the grip and grip of the knife. Discreet carrying of the knife in the pocket is possible thanks to the high-mounted clip (one-sided) secured with a Teflon coating.
