Contoured polymer grip Spring steel pocket clip BackSet key ASP Handcuff Keys are designed to withstand the rigors of long term duty use. Conventional keys are stamped from mild steel. They often break or twist off in a handcuff. These ''key jammed'' restraints create civil liability. Each ASP key is hammer forged, then precision machined. Keys are heat treated for strength and coated with a protective finish. The unique ASP BackSet feature allows rapid location of the handcuff keyway. Clip keys provide an extended reach and convenient pocket clip.
