Abstract: The invention is an improved cutting blade for use in connection with a rotary wire stripper. The blade is notched in a manner so as to define one or more chipping points along the blade's edge. The notches are interconnected by sharp sections of the blade's edge. This configuration permits cutting through both hard and soft forms of wiring insulation. If the insulation is hard, the corners provided by the notches chip through it. If the insulation is soft, the sharp edges cut through it in conventional fashion.

Abstract: A tool for removing the insulation covering of a coaxial cable. The tool has first and second through holes. The portion having the first through hole will support a cutter member able to adjust the cutting in length of the blade into the outer insulation covering. A scraper member is arranged to scrape-up and cut-off scraps and peel off the insulation covering when the tool is rotated relative to the coaxial cable; the cutter blade cuts in the outer insulation covering in a spiral manner.

Abstract: An apparatus for removing a jacket from an underlying member such as a cable includes a tubular housing, a knife edge and a dial for positioning the blade. In an "open" position the blade is retracted from the housing to permit insertion of a cable into the housing. Rotation of the dial to a "CUT" position positions the blade on the cable, the blade substantially perpendicular to the cable, so that rotation of the remover circumferentially scores the cable jacket. Rotating the dial to a "strip" position angles the blade with respect to the cable so that rotation of the remover on the cable helically scores the cable jacket while the device tracks to the end and off the cable. The cable jacket is then removed by unwrapping the resultant helical strip of jacket from the cable end to the circumferential score line. The cable jacket remover is made of a plastic such as polyvinylchloride pipe to reduce a shock hazard and includes a scale for measuring the terminal length of cable to be stripped.

The adjusting screw includes a torque head that limits adjusting screw torque to a predetermined amount. The present invention includes a positive stop used as a home position for each blade.

The use of a V-notch eliminates dragging of the braid and the possibility of one or more wire strands thereof wrapping around the center conductor. It also eliminates nicking of the center conductor which can cause poor transmission signals.

Abstract: Stripping of the outer jacket of miniaturized coaxial cable is achieved through the use of stripping blades which have surfaces dulled to preclude cutting the cable core or ground conductor and yet sever the cable and metalized film from the cable core. The stripping blades have an offset to eliminate the need to orient the cable relative to the ground wire with the dull surfaces having a radius to substantially deform the cable with the cable then being pulled to effect removal of the outer jacket and metallized film. The length of stripping accommodates axial elongation of the core with excess core subsequently being trimmed, thereby resulting in a desired stripped length.
