ABSTRACT:
A pair of support members are slideably inserted into a rectangular shaped open ended housing from opposite ends of the housing. Each support member has a downwardly extending projection to form facing cutting surfaces. A resilient member presses the support members toward each other forming a ski sharpener. When the sharpener is placed against and moved along a ski the cutting surfaces sharpen the sides of the ski.
