This SRK model is equipped with a durable SK-5 steel blade and Cold Steel's black Tuff-Ex coating for a tough, corrosion-resistant blade. The Cold Steel SRK (Survival and Rescue Knife) is a versatile knife capable of withstanding the harshest conditions. It features a very strong drop point tip, precise enough for delicate tasks, yet with enough belly for efficient chopping, slicing, and skinning. At 3/16" thick, the Survival and Rescue Knife offers the strongest possible tip and edge design, without sacrificing sharpness. The SRK's handle features a single-layer finger guard and a deeply checkered Kray-Ex handle. The product includes a Secure-Ex sheath for comfortable everyday carry.
