ABSTRACT:
A palm held tool for slitting the insulating sheath of a sheathed three-conductor electrical cable and spreading the outer conductors laterally away from the central conductor is provided. The tool comprises a housing and a pair of spaced rotary cutters, each cutter including a piercing point, a slicing edge and a curved wedge thereon. Upon rotation of the cutters, the piercing point on each cutter pierces the cable at a point in the cable and each slicing edge progressively slices the cable longitudinally unidirectionally from such pierced point between a respective outer conductor and central conductor. The curved wedge subsequently enters the slit cable progressively longitudinally unidirectionally and laterally spreads the outer conductors therealong. During a complete revolution of the cutters, the piercing points, slicing edges and curved wedges sequentially enter, pass through and exit the cable.
