Abstract

A pair of pliers for gripping, twisting, and cutting wires having undulating wire gripping surfaces, a wire cutting cavity, and a resilient wire gripping material. The undulating wire gripping surfaces have high and low portions that unequally traverse the gripping surfaces and extend unequally beyond the centerline of the pliers. Such a configuration provides an equally distributed gripping force for an entire range of wires without causing any nicks and scrapes on the wire. The cutting cavity has a plurality of surfaces that form tiger tooth-like members. The geometry formed by the cavity's surfaces and tooth-like members provides a large surface area for the resilient gripping material to adhere to.
