ABSTRACT:
A knife sharpening apparatus includes a moving abrasive surface. A magnetic guide has a guide surface in a plane disposed at a predetermined angle which intersects the plane of the abrasive surface. The magnetic guide is made from a magnetized material having opposite polarity north and south magnetic pole faces with a first ferromagnetic member located against one pole and a second non-planar ferromagnetic member located in part against the other pole and in part extending parallel to the guide surface and contiguous to the magnetized material. The second ferromagnetic member is located at the surface remote from the abrasive surface.
