ABSTRACT:
A tool for stripping tubular insulation off of a wire without contacting the wire comprises a hollow body in the shape of a pistol having a nose at one end with an aperture upon a longitudinal axis, adapted to axially receive an insulated wire to be stripped, a pistol grip and a trigger pivotally mounted within the body, which includes a fixed jaw. An upper jaw overlies the fixed jaw, extends into and is pivotally mounted upon the body and terminates in a jaw arm. A resilient wire stripper is operably nested and retained between the jaws and includes a pair of opposed outwardly biased support arms terminating in a pair of opposed spaced transversely slotted blade mounting heads with co-planar blades secured within the heads having opposed semi-circular openings at their meeting edges of a radius slightly greater than the radius of the wire. A cam upon the trigger is arranged adjacent to the jaw arm so that initial manual retraction of the trigger moves the cam to operatively engage the jaw arm for pivotally closing the movable jaw relative to the fixed jaw with the blades cutting through the insulation.
