A sharpener for industrial knife blades comprises a frame for retaining the blades therein, and an elongate beam having an inelastically deformable way surface. A grinder is slideably mounted on the beam by rollers which abuttingly engage the way surface. The rollers and the way surface are urged together, whereby repeated translation of the grinder along the beam causes the rollers to impress a hollow or concave track in the way surface, wherein the rollers are retained and guided for accurate grinding of the knife blades.
