A process and an apparatus for sharpening of knives. The apparatus comprises a holder for the knife, a sharpening element, structure for displacing the sharpening element along the edge of the knife with a predetermined angle between the plane of the knife blade and the finishing surface of the sharpening element. Structure is arranged to periodically shift the engagement between the sharpening element and the knife between the two sides of the edge. Structure is arranged for relatively displacing the sharpening element transverse to the longitudinal direction of the edge, and the sharpening element is arranged with successively increasing sharpening fineness in said transverse displacement direction. The highest sharpening fineness of the sharpening element is formed by a sharpening steel section. The transverse displacement structure is arranged, during a sharpening operation, to displace the sharpening element related to the knife holder to successively bring the knife edge to engage the sections with higher sharpening fineness of the sharpening element. |
