1. A tool comprising:
a grabber arrangement being movable from an open disposition for receiving a cable, conduit or pipe within the grabber arrangement to a closed disposition defining a through-hole for grabbing and retaining the cable, conduit or pipe along a center line C;
a cutter arrangement disposed axially adjacent the grabber arrangement and including a cutter body defining a cutter slot being open towards the center line C;
a hydraulic cylinder operatively coupled to the cutter arrangement and configured to apply a hydraulic pressure to the cutter arrangement to slide the cutter arrangement relative to the grabber arrangement from a distal position wherein the cutter slot is radially spaced from the center line C to a proximal position wherein the cutter slot is disposed along the center line C and receives the cable, conduit or pipe therein;
the cutter arrangement including an anvil movable from a first anvil position to a second anvil position in response to the cutter arrangement being disposed in the proximal position to slide the anvil in radially spaced relationship with the center line C and close the cutter slot around the cable, conduit or pipe in the second anvil position; and
the hydraulic cylinder switchable to a free float condition in response to the anvil being disposed in the second anvil position, wherein the free float condition is configured to remove the hydraulic pressure applied to the cutter arrangement and allow the cutter arrangement to freely move from the proximal position back towards the distal position until the anvil is disposed in abutting relationship with a bottom portion of the cable, conduit or pipe.
