<p>A knife sharpening apparatus includes a moving abrasive surface (40). A magnetic guide has a guide surface (30) in a plane disposed at a predetermined angle which intersects the plane of the abrasive surface (40). The magnetic guide is made from a magnetized material having opposite polarity north and south magnetic pole faces (N, S) with a first ferromagnetic member (12) located against one pole (S) and a second non-planar ferromagnetic member (22, 26) located in part against the other pole (N) and in part extending parallel to the guide surface (30) and contiguous to the magnetized material. The second ferromagnetic member (22, 26) is located at the surface remote from the abrasive surface (40).</p> |
