ABSTRACT:
A knife or blade is sharpened by using an apparatus which includes a magnetic guide having a magnetic knife guide surface in a plane at an angle to and intersecting the abrasive surface to form a line of intersection therewith. The magnetic guide surface has north and south magnetic poles along lines substantially parallel to the line of intersection. One pole is along a portion of the guide surface remote from the abrasive surface and the other pole is along a portion of the guide surface contiguous to the abrasive surface.
