The Zero ToleranceZT Sinkevich 0452CF is a large gentleman folder, featuring a ball-bearing CPM-35VN steel head, titanium and carbon fiber liners, and a convenient flipper unfolding system.
The Zero Tolerance ZT 0452CF is the result of a fruitful collaboration between Zero Tolerance and Belarusian designer Dmitry Sinkevich. The ZT 452CF knife is the same size as the classic 0454 folder, but is distinguished by a carbon-fiber front liner, higher-quality S35VN steel and a double-finished blade.
American stainless steel
The slim 104mm long head is made of American CPM-S35VN powder steel. This grade of stainless steel features high impact strength (58-60 HRC hardening), wear and corrosion resistance, and extremely long sharpness retention.
Unlike its predecessor CPM- S30V, CPM- S35VN is much easier to sharpen due to the finer grain of the steel and the admixture of niobium. However, due to the high hardenability and impact strength of CPM-S35VN steel, we recommend using diamond whetstones for sharpening.
Thanks to its strong tip, gentle edge curvature and flat grind, the blade penetrates perfectly and provides very good cutting properties. The blade has a double finish: satin-finished on the grind and stonewashed at the top.
The thickness of the blade at its widest point is 4 mm, which is a compromise between durability and functionality of the knife in everyday work. On the back of the blade are applied transverse cutters, which create a very stable place of support for the thumb or index finger.
The advantages of this solution will be appreciated by every user of the knife during planing or precision cutting.
Instant unfolding of the blade
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, making the daily use of the knife a pure pleasure.
Work safety
A monolithic frame-lock equipped with a hardened steel insert against titanium abrasioneffectively protects the head from accidental folding. Frame-lock is a solid lock considered one of the most durable locking mechanisms, characterized by resistance to dirt and very comfortable operation.
Modern materials
The knife has contoured liners made of the highest quality materials, i.e. titanium and carbon fiber. Titanium is characterized by light weight, total resistance to corrosion, mechanical damage, and is not sensitive to high temperatures, acids and seawater.
Carbon fiber is an extremely lightweight and durable material, which undeniably gives the knife a prestigious look. The elegant character of the knife is emphasized by polished spacer sleeves strikingly anodized in emerald green.
Convertible clip
Discreet carrying of the knife in the pocket is made possible by a high-set clip with the possibility of mounting on both sides of the handle. On the handle, in addition to the clip, there is also a hole for attaching a decorative braid or safety line.
