An edge sharpener is a hand-held device for grinding and sharpening ski and snowboard steel edges at a specific angle.
There are versions that can sharpen the base and side edges and versions that only sharpen the side edge. Depending on the model, the grinding angle can be set continuously or in certain degrees. The world's largest manufacturers of edge sharpeners are SKS-Kunzmann (DE) and SKIMAN (IT).
