ABSTRACT:
A hand-held tool having an elongated rod-like body with an arcuately-shaped head tapered to a rounded point for use in removing insulated wires from the end of a braided shielded cable. The tip is intentionally rounded to prevent puncturing the insulation or catching on the braided wires when the tip is inserted between the wire insulation and the shield. The outer 1/2 of the tapered head portion has a substantially elliptical cross section, as opposed to simply circular, to distribute the load bearing forces across a greater surface area on the wire insulation when the wire is pulled out of the shield. The other 1/2 of the tapered head portion is a transition to the cylindrical body from the curved ellipsoidal section. In a preferred embodiment, the tool is constructed of a polycarbonate plastic with a smoothed surface on the tapered head portion to facilitate the insulated wires sliding across the surface during use. Also in a preferred embodiment the cylindrical body has two side walls to facilitate gripping of the tool by the user.
