New from ASP: hinged stainless steel handcuffs with three part pawl for higher security. The pawl is the part that engages the teeth of the swinging bow of the handcuff. Making it with 3 independently operating sections makes the handcuffs more resistant to shimming. ASP calls them European style. Hiatt (now Safariland) has been using this feature for years and triple pawls are required by some European agencies. Green double locks differentiate these from standard ASP handcuffs. They use standard keys and operate just like other ASP handcuffs.
