ABSTRACT:
A wire stripper blade for cutting to the center conductor of a coaxial cable, the blade having a V-notch in the cirmcumferential periphery thereof. When the wire stripper is rotated about the cable, the corners of the V-notch cut through and sever the braid sheath and inner insulation layer of the cable, while the center conductor remains within a circle defined by the corners of the V-notch, which circle is spaced apart from and concentric with the center conductor. 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.
