In order, in the case of a punch which is used for punching out, especially of pincer limbs, to create a corresponding aperture in the lower part (4) of the respective shape of the workpiece to be punched out, one longitudinal side of a rectangular block (6) which is replaceably fastened on the lower part (4) forms a shearing edge (8) which is designed to match the outline of one longitudinal edge of a limb (7) of the pincers and is operatively connected to the cutting element (3) of the punch. Furthermore, at least one elongated guiding arm (9 and 14 respectively) is in each case adjustably arranged on the lower part (4) and on the cutting element (3), which guiding arms enclose between them the original material (16) which is fed to the cutting element (3) in an inclined manner and act as a guide for the original material (16) as the latter is advanced, an elongated arm (17), which limits the advancement of the original material (16) and acts as a stop, being adjustably arranged on the cutting element (3). <IMAGE>
