Spyderco - ARK Always Ready Knife H-2 Steel FRN Handle

The Spyderco ARK (Always Ready Knife) is a purpose-built, ultra-light self-defense and utility blade designed by U.S. Army combat veteran John Shirley and his friend Sam Owens. Engineered to be carried anywhere, even in the most demanding environments, the ARK combines corrosion-proof performance with dependable grip and cutting power.

Its deeply curved clip-point blade is hollow ground from H-2 steel, a nitrogen-based alloy renowned for extreme corrosion resistance—ideal for maritime, outdoor, and survival use. Despite its compact size, the ARK delivers impressive slicing ability and control for everyday cutting or emergency defense situations.

The fiberglass-reinforced nylon (FRN) handle is molded directly to the tang and features Spyderco’s Bi-Directional Texture™ pattern, ensuring a secure, non-slip grip even with wet hands. Each knife comes equipped with a polymer sheath featuring an integral retention tab and a breakaway ball chain for discreet neck carry or quick deployment.
