Zero Tolerance ZT 0308 is a popular EDC knife , equipped with a bearing CPM-20CV steel blade , carbon fiber cladding that glows in the dark and a convenient flipper folding system. premium steel The 89 mm long blade was 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, it 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. The aggressive blade resembles a harpoon blade with its exotic shape . Thanks to the use of a strong tip, gentle curvature of the edge and a flat grind, the blade penetrates perfectly and provides very good cutting properties. The thickness of the blade at its widest point is as much as 4 mm, which guarantees durability and functionality during work. On the back of the blade there are transverse milling cutters that create a very stable place of support for the thumb or index finger. Comfortable unfolding 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 very smoothly and dynamically, which will be appreciated by every user during everyday use. A monolithic frame-lock equipped with a hardened steel insert , preventing the abrasion of titanium, effectively protects against accidental folding of the blade . 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. Spectacular gimmick The knife has profiled titanium facings , to which stylish carbon fiber inserts are attached , which glow in the dark when exposed to light. In dark places, the knife emanates a delicate green glow that can help you find the knife at night. On the edges of the titanium linings (lower part), transverse milling was machined, ensuring a stable and safe grip. Reversible clip There is also a clip that can be screwed on the right or left cladding depending on your preference. The clip is compatible with clips from other manufacturers, e.g. Emerson, thanks to which the user can adapt this element to his own needs.
