A medium/high carbon low alloy steel which can be cold formed by cold or warm forging and heat treated. The material consists essentially of:

Medium/high carbon low alloy steel for warm/cold forming

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.

Composite/plier cutter tool with shear action cutter insert

A totally non-metallic wrench formed entirely of fiber-reinforced plastic material includes a core of random discontinuous glass-fiber-reinforced plastic material and a band of unidirectional continuous glass-fiber-reinforced plastic material extending around the periphery of the core which are subjected to compression molding to form a composite wrench structure.
