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). Spreading surfaces (72) adjacent to the edges (70) spread the collar material away from the fastener shaft. The lever (56) has cam surfaces (60, 62) that engage a hook (78) on the rear end of the slider (68) to move the slider (68) forward and back perpendicular to the fastener shaft axis (X).
