Abstract
A hand tool for stripping insulation from the end of a wire includes a pair of gripping jaws for holding the wire and a pair of cutting and stripping jaws for removing the insulation. An actuating member is pivotally connected at one end to the cutting and stripping jaws and at the other end to a pivotally mounted driving member. When a pair of handles on the tools are pressed toward one another, the two pair of jaws engage the wire, one pair holding the wire while the other pair cuts and strips the insulation. During this operation, the actuating member displaces the cutting and stripping jaws away from the gripping jaws and pulls the cut insulation at least partly off the end of the wire.
