Title
(EN) KNIFE BLADE SHARPENING DEVICE AND METHOD
Abstract
(EN)

The device includes a holder for retaining the knife blade in a fixed position with the cutting edge accessible from above. One end of a moveable abrasive part is situated above the cutting edge. The other end of the abrasive part is supported by a retaining member and sets the angle of the abrasive part relative to the knife blade when the abrasive surface contacts the cutting edge. The cutting edge is sharpened as the abrasive part in contact with the cutting edge is moved along the length of the knife blade. The abrasive part may be a stone or a rod with an abrasive surface. The retaining part may have a ring shape or take the form of a clamp which attaches to the stone in different positions.
