  • Hand tool for removing collar from lock bolt
    Patent number: 4989325
    Abstract: A tool body (32) has a forward cradle (34) that surroundingly receives a fastener collar (14). A slider (68) is slid in a cavity (40) in the body (32) by a lever (56) pivotably attached to the body (32). Cutting edges (70) on either side of a slot (74) in the slider (68) cut the collar (14).
