Abstract
A sharpener for blades comprises a physical structure supporting at least one abrasive surface. A displaceable guiding plate having an integral linear structural feature of the support is disposed toward one side of the abrasive surface. The linear structural feature provides sliding contact with a face of the blade to establish the relative angle of the plane of the edge facet of the blade with the plane of the abrasive surface at the point of mutual contact as the facet is guided into contact with the abrasive surface.
