  • Insulation stripping tool
    Patent number: 6012357
    Abstract: A tool for stripping insulation from the conductor core of a wire or cable includes a pair of longitudinal members which are pivotally interconnected. The tool also includes a pair of blade assemblies, which are removably mounted on the longitudinal members. The blade assemblies can include grooves which cooperate to form openings for passing the conductors while stripping the insulation layers therefrom. The blades can comprise resilient materials, such as polymers, to reduce the risk of cutting the conductor.
