Now one of our most popular ZTs comes in BlackWash. BlackWash gives the blade a well worn look, like a battle-tested tool. It also provides an extra measure of protection for the blade, helps hide hard-use scratches, and reduces friction. The 0350BW features the patented SpeedSafe assisted opening system. Deploy the blade quickly and easily, even in gloves, using the ambidextrous flipper. The ZT 0350BW’s blade is S30V stainless steel with non-reflective Tungsten DLC (Diamond-Like Carbon) BlackWash coating. S30V steel is extremely durable, corrosion resistant, and wear resistant.
