Zero Tolerance ZT Martin 0609 is a medium-sized everyday knife , based on the limited Factory Custom 0606CF model, which was designed in collaboration with RJ Martin. The ZT Martin 0609 model was created primarily for convenient carrying and everyday use. Like its predecessor, the ZT 0609 has a slim design with optimal size , a functional premium steel blade, a titanium handle with a great finish and an eye-catching design. American stainless steel The 86 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 wide blade with a useful drop-point profile has a double finish: satin on the cut and stonewashed in the upper part. Thanks to the use of a strong point, gentle curvature of the edge and a flat grind, the blade penetrates perfectly, and the cutting process is very smooth and light . 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 . 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 . The advantages of this solution will be appreciated by every knife user during planing or precise cutting. Rapid unfolding of the blade The blade can be quickly unfolded with one hand using a milled flipper. The fin allows for easy and comfortable opening of the blade for both right and left-handed people. On the axis of the blade there are KVT ball bearings, thanks to which the blade works very smoothly and dynamically , and everyday use of the knife is pure pleasure. The custom pivot with a through hole is an intriguing and eye-catching design by RJ Martin. Work safety A monolithic frame-lock equipped with a hardened steel insert, preventing the wear 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. Exclusive linings The knife has bronze anodized titanium cladding , with effective and aggressive texturing made in precise 3D technology. Titanium is characterized by low weight, total resistance to corrosion, mechanical damage, and low sensitivity to temperatures, acids and sea water. The handle has an anatomical profile that perfectly fits the hand, thus ensuring comfort, stable grip and safety of use. Reversible clip Discreet carrying of the knife in the pocket is possible thanks to the high-mounted clip with the possibility of mounting on both sides of the handle.
