Abstract (en)
The sharpener has a guide channel in its casing (1)for the front end of the stick (3), a tangential sharpening blade (4) and a casing projection made in one with the sharpener casing to shape the stick in the manner of a template. The casing projection (7) carries on its end a narrow shaving rib (11) which is wedge-shaped in cross section, with the wedge apex (9) extending over the casing projection in a tangential working direction (10), to shape the stick. The wedge angle of the shaving rib may be between 70 and 45 degrees .
