The ARK - or "Always Ready Knife" is a purpose-designed personal-defense knife conceived by U.S. Army combat veteran John Shirley and his friend Sam Owens. The heart of the ARK is its deeply curved clip-point blade ground from H-1 steel - a nitrogen-based alloy that is completely immune to rust. The curved edge packs impressive cutting power into the compact blade and the clip-point profile ensures a strong, extremely sharp point. The ARK's fiberglass-reinforced-nylon (FRN) handle is molded directly onto the tang and features Spyderco's proven Bi-Directional Texturing pattern and an index-finger groove to guarantee a secure grip—even with wet hands. To ensure universal carry, the ARK includes an injection-molded polymer neck sheath with a breakaway ball chain.
