Our flagship knife looks great in this new tungsten DLC BlackWash finish. BlackWash gives the 0300BW a well worn lookâsimilar to a battle-tested tool or a favorite pair of perfectly broken-in jeans. The 0300BW has all the features you expect from your ZT extremely solid construction, premium materials, and sophisticated ergonomics. The blade is built of tough S30V stainless steel blade designed to provide the ideal combination of durability, wear resistance, and corrosion resistance. The BlackWash finish provides a non-reflective surface and helps emphasize the lines of the blade.
