Abstract

The hammer (12) has a percussion surface (13) for shaping a work piece (10') at different contact points (KP, KP', KP'') of the percussion surface. The percussion surface includes a concave curve section in a normal plane of a longitudinal axis of the hammer. The curve section is varied between a crown line (26') of the percussion surface and edge regions of the surface. Each contact point exhibits a curve radius (R) defining a circle of curvature with middle points (M, M', M''). The middle points lie in a middle symmetry plane (24) extending along the axis and contain the crown line.
