Abstract: This invention relates to a novel cutting tool. More particularly, this invention relates to a novel cutting tool which is specifically adapted to cutting the sheath of conducting cable without cutting or damaging the underlying conducting elements of the cable. A cutting tool useful for cutting sheathing on a cable comprising: (a) a holder for holding a cutting blade in a retracted or in an extended position; (b) a mechanism for pushing manually the blade from a retracted to an extended position and alternatively from an extended position to a retracted position; (c) a spring for urging the cutting blade into a retracted position when the cutting blade is in an extended position; and (d) a blade travel stop for controlling the distance that the cutting blade extends from the holder when in an extended position.
