ABSTRACT:
A composite, non-electrically conductive, non-sparking, non-magnetic and lightweight cutter/plier hand tool has two pivotally interconnected lever members, each of unitary, one-piece construction and formed by compression molding of multiple plies of a discontinuous random glass fiber-reinforced plastic sheet molding compound. Fixed to the jaw of each lever member is a ceramic insert made of transformation toughened zirconia, formed by dry compression and then sintering of a powdered form of the ceramic material. Each insert has a serrated gripping portion and a cutting portion, with cutting surfaces on the opposed inserts operating in shearing relationship. Three versions of the inserts are disclosed.
