The new Tuff Kuff handcuffs are now in stock. The most innovative handcuffs to come out in a long time, the heavy duty stainless steel construction and high quality makes these handcuffs really stand out. Handcuff inventor and retired police officer Paul Amo has gone to great lengths to make the best handcuff possible. The primary innovation is the center hinge which pivots only in one direction. This allows an officer to rotate the subject’s hands to position them in a stacked position. This reduces the risk that the subject could grab objects, manipulate handcuffs, or slip the handcuffs from back to front. Tuff Kuffs also have keyholes on both sides of each cuff and feature sliding S&W style double locks. Tuff Kuffs have about the same maximum opening size as other standard sized handcuffs, but the design of the swinging bows allows them to close smaller to work on prisoners with small wrists.
