Abstract

See full text

The blade of a folding knife is pivoted on a D-shaped pivot axle which also serves to lock the side pieces and belt clip of the knife in place. A thumb pin used to open the blade is also D-shaped and press fit into place in the blade. The blade has transverse grooves at its base to aid in extracting the knife from a sheath. The blade is locked into place by a side-lock plate, which is held in place by ridges in the side pieces. The side pieces are preferably made of rigid plastic, but with soft inserts in the sides for improved gripping.
