Abstract: A sharpener for steel edges of skis comprises a compact, inexpensive, portable holder containing a cutting plate and a guide pin. The cover for the holder can be positioned to serve as a handle. The cutting plate preferably forms an angle of less than 90.degree. with the steel edge of the ski to be sharpened.

Abstract: An edge sharpener, in particular for sharpening the steel edges of skis, is composed of a main body in which there is a recess for holding a file blade and within which is inserted a clamping wedge so as to exert distributed forces on the surface area of the file blade when the clamping wedge is forced into the recess substantially radially. In a particular feature of the invention, the main holder has a flexible foil which comes to lie between the pressure surface of the clamping wedge and the surface of the file so that movement of the clamping wedge does not result in abrasive contact with the surface of the file. The lower part of the clamping wedge has an inclined surface which cooperates with a similarly inclined surface in the holder. The clamping wedge is further equipped with gripping surfaces so that, during manual use, the force of the hand on the sharpener to execute the sharpening strokes tends to move the clamping wedge more forcefully into the recess, thereby increasing the clamping action.
