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 Rescue Knife) is a versatile knife capable of withstanding the harshest conditions. It features a very strong, pointed tip, precise enough for delicate tasks, while still having enough belly for efficient cutting, skinning, and slicing. At 3/16 inch thick, the SRK offers the strongest possible blade design and edge, 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.
