Abstract: A device is provided which is useful in stripping wires and cables having a non-uniform outer contour. A single point knife blade is mounted on a lever arm adjacent an adjustable cam. The knife assembly is mounted on an elongated tool body having an axial passage to receive the wire or cable. The knife blade is resiliently biased into cutting contact with the cable to a depth limited by engagement of the cam with the outer contour of the cable. As the tool is rotated, the cam rides over the external contour of the cable thereby maintaining a fixed depth of cut in spite of the non-uniform contour.
