Abstract
A knife sharpening apparatus adjustable to maintain a knife at a preselected angle during sharpening. The apparatus includes a platform adapted for supporting a sharpening stone thereon, and a support assembly mounted for shifting along a path substantially normal to the plane of the platform. A bar used in guiding the top edge of a knife blade is mounted on the assembly for shifting relative thereto along such path. To adjust the apparatus, the bar is placed at a 'zero' position on the support assembly, and the latter is shifted to place the bar against the top of the stone. The bar is then shifted away from its 'zero' position a preselected distance to produce a desired spacing between the bar and the stone, wherein, with a knife blade placed with its working edge against the stone, and its opposite edge against the bar, the blade is held at a desired preselected angle.
