Abstract: A small, hand-held tool for removing the outer sheath of plastic material covering a bundle of individually insulated electric conductors, with special capacity for the twisted surface of three-conductor non-metallic sheath cable. Important features of the tool include a short, dull, hook-shaped claw for safely effecting an opening in the side of the sheathing sufficient to admit the guide-shoe at the tip of the blade; a crescent-shaped blade for both slitting the sheathing and for chopping off the residue of slit sheathing; a thin, flat shoe with its broadest part near the leading edge; and a handle so shaped with gripping lobes and so positioned relative to the shoe as to offer a firm pulling grip while permitting the first finger and thumb to help position and guide the tool during the slitting operation.
