A cutting tool having a work piece feed mechanism includes a first jaw and a second jaw connected together for pivotal movement between a closed position and an open position. The work piece feed mechanism includes first and second ratchet members as well as a slide member adapted to engage a work piece and mounted for movement between a fully extended position and a fully retracted position. Movement of the first and second jaws from the closed position to the open position causes the first ratchet member to operably engage the slide member and incrementally advance the slide member toward the fully retracted position. Movement of the first and second jaws from the open position to the closed position causes the second ratchet member to operably engage the slide member to restrain the slide member from movement toward the fully extended position.
