Abstract: Cartridge-actuated cutter (10), held in a single hand, generally includes frame (20) and barrel assembly (40). Frame (20) includes grip (26), trigger (30) firing pin (28), and pivot mount (35). Barrel assembly (40) generally includes barrel (41), piston (70), and extractor (80). Barrel (41) includes anvil (52), cable receiving recess (55), breech bore (61) for receiving a cartridge, and longitudinal bore (64). Piston front end (74) includes chisel (75) and stop (76). Detonation of the cartridge drives piston (70) forward from a cocked position to cut a cable in recess (55) against anvil (52). Extractor (80) slides rearward to simultaneously eject a cartridge and cock piston (70). Stop (76) impacts anvil (52) simultaneously with chisel (75). Anvil (52) is repositionable so as to present different surfaces to chisel (75). Barrel (41) includes second pivoting mount (45) for repositioning recess (55) relative to frame (20).

Abstract: A combination anti-rotation and counter-recoil device for a sub-caliber barrel positioned inside a larger caliber barrel gun which utilizes a plate attached to the flat base of the tubular member simulating the cartridge case within the larger caliber gun and is held in position by two arms preventing rotation of said member and also a spring loaded piston is provided which engages an opening in the plate which provides for counter-recoil force after each firing.
