  • Patent number: 4829671
    Abstract: A copper cable wire peeler is disclosed. The peeler consists of biased jaws which, at one end, mount two blade cutters in the lower jaw disposed at different heights which blade cutter heights are adjustable by set screws. The upper jaw mounts a clamping member so that when the wire to be peeled is inserted, inner and out sheaths can be peeled from a copper wire. The blade cutters are also biased to permit fluctuations in the thickness of the wire due to low manufacturing tolerances.
