Abstract
A hand tool is disclosed for installing mallable rivets into a workpiece and for removing such rivets. The hand tool comprises a generally C-shaped body that has a clamp sleeve and a coaxially rivet forming member extending towards a coaxially located punch member. A workpiece is placed between the clamp sleeve and the punch member and the clamp secures the workpiece against the punch member. If a rivet is to be removed, the rivet forming member is retracted and the punch member is advanced to remove a rivet. If a rivet is to be installed, the punch member is partially retracted and the head of the rivet is rested thereon, then the rivet forming member is advanced against an end portion of the rivet extending from the opposite side of the workpiece.
