A bone punch includes a base body with a guide shaft (3), a handle (4) and a punching slide (8) supported adjustably along an upper guiding surface (13) of the guide shaft (3). An actuating lever (6) with an adjusting lever (65) interacts with the punching slide (8) for adjustment against a spring action of a restoring spring (46). In a distal end area (10), the punching slide (8) has a securing element (45), which extends between two side walls (25, 26) of the punching slide (8) on the guide shaft (3). The securing element (45) has two laterally protruding positive-locking elements (51, 52). Each side wall (25, 26) is provided with an inner, distally limited longitudinal groove (40, 41) running in the longitudinal direction (9) of the guide shaft (5). Each positive-locking element (51, 52) is longitudinally displaceably inserted into a respective one of the grooves (40, 41).
