The first grinding wheel (81) has a finer grain than the second grinding wheel (83). Moreover, the first grinding wheel also has an inclination that is not par­allel to the respective first side (207) of the bevel (205) of the blade (19), while the second grinding wheel (83) has an inclination essentially parallel to the second side (209) of said bevel.
