摘要

The wedge has a striking head (2) with two opposite sides joined at a cutting edge (3) by a pair of sides. Each of the pair of sides is partially plane. The plane part of the side pair forms a facet (9) that is bordered by the cutting edge and by an adjacent part of one of two longitudinal edges. The adjacent part has a length ranging between 25 and 30 percent of the length of the longitudinal edges.
