Abstract
A sharpening guide is provided for manual sharpening of a blade at a fixed angle on a sharpening stone. The guide is an elongate, wedge-shaped strip coated on one face with adhesive. It is removably adhered to one face of a blade to be sharpened. The second face of the wedge is held flat against the sharpening stone and the angle of the wedge maintains a fixed angle for grinding the edge of the blade. The guide is removed by lifting by a release tab extending from the back of the wedge and it is then stuck on the second face of the blade to sharpen the second side of the blade. The strip is provided in straight form and in curved form. Appropriate lengths are broken off to suit a particular blade configuration. The guide may be provided in various angles of wedge and various radii of curvature. The strip may be provided in materials that do not readily grind off and load the abrading surface. Optionally, the strip is made of a material which is readily washed off the sharpening stone if it becomes loaded.
