Abstract

A wire stripping tool for moving insulation from the end of electrical wiring having a first, elongate cutting member providing a first handle at one end and a first cutting edge at the opposite end thereof and a second cutting member providing a second cutting edge. Each cutting edge has a wire-receiving notch therein. An elongate insulation removing member has a second handle at one end and an insulation pulling edge at the opposite end thereof. A pin member pivotally connects together the first and second cutting members and the insulation removing member at a location close to the cutting edges. A stop member on the first cutting member prevents continued pivotal movement of the first cutting member relative to the second cutting member beyond a selected point. A spring is connected between the insulation removing member and an end of the second cutting member. The spring biases the insulation removing member to a position where the pulling edge is beside the second cutting edge. The tool is capable of pulling a severed end piece of insulation off the metal wire by a single pull of the handles towards one another.
