The Sand Shark from Desert Knife Works is a true synthesis of utilitarian design, craftsmanship, and function. This model features a satin-finished double-edge dagger blade with plain edges. The ergonomic body is gray anodized T6 aluminum with a "stepped" firing button. The Sand Shark is a double-action OTF knife, meaning it fires and retracts automatically via the sliding firing button on the face of the knife body. An automatic knife that's well-known by collectors and is a big hit with knife nuts everywhere!
