The black blade is made of 440C stainless steel with high strength, abrasion resistance and corrosion resistance, which is especially important for those who do not have a sharpening experience. The 69 mm long blade has a symmetrical nozzle profile, which provides effective penetration and good cutting properties. The blade is 2.8 mm thick, which provides durability and easy cutting. Walther CSK uses a sliding connection safety mechanism - a simple spring lock that prevents the blade from falling and unfold. Because the blade can be closed with a small force, the slip mechanism is not considered a full-fledged knife.
