Abstract: A hand-held tool for forming a rivet head at the plain end of a rivet includes an elongated handle having an elongated internal cavity with a guide wall surface extending to an adjacent guide wall surface in an insert having an end wall. The end wall is provided with a predetermined thickness and contains an aperture to house a shop head formed on the plain head of a rivet. An inertia block is slidably guided by the guide wall surfaces of the handle and insert for reciprocation between a displaced position remote from the end wall and a position for contact with the end wall. A spring located in the elongated handle urges the inertia block against an end of a rivet when protruding from the aperture in the end wall and arrests recoiling movement of the inertia block after impact with a rivet end in a direction away from the end wall.
