Abstract
A blade-sharpening sheath contains sharpening elements (31) resiliently mounted in a crossed arrangement so as to define between them a blade-sharpening cavity which extends above a line (P) of intersection of the sharpening profiles (34). The rest position of the sharpening elements (31) is defined by abutment shoulders (42c) in cooperating relation with the sharpening profiles beneath the line (P). The abutment shoulders (42c) are carried by ribs (42) and the inner edge (42b) of each rib serves to guide the knife blade (48). The distance (h) between the tip (52) and the back (49) of the blade is slightly shorter than the distance (H) between the line (P) and the bottom of a groove (43) for guiding the back of the blade. The cutting edge (51) of the knife blade is inclined with respect to the back (49) of the blade.
