Abstract
Abstract A hand-operated tool for scoring or severing the outer insulation layer or layers of insulated wire to enable the same to be removed from such wire. The tool includes a U-shaped member having a cutter block fixedly attached and a body member slidably attached thereto, with at least one circular blade eccentrically and adjustably mounted on the cutter block to transversely engage an insulated wire supported by the body member.
