Abstract
A support device for facilitating the sharpening of a knife blade or the like is provided. The device is a solid block of rigid material having a flat lower surface to rest on a stable surface and an upper surface parallel to the lower surface. The upper surface has an elongated arcuate channel therein which extends the length of the block. Two spaced apart lips extend horizontally along the upper edges of the channel and extend slightly inwardly of the upper edges of the channel towards each other. A knife having a width greater than the width of the channel is inserted into the channel with its cutting edge extending out of the channel for sharpening, its non-cutting edge abutting against one of the lips, and the side if the knife abutting against the other lip. Thus the knife is held at the proper angle for sharpening with a stone.
