ABSTRACT:
Embodiments of a ski sharpening guide are shown and described, each embodiment including an angular member having a side surface for placement against a ski and a top surface for holding a file. Preferably, a channel runs along the junction between the side surface and the top surface along the entire length of the angular member, for collection of filings. Preferably, the top surface includes a filing-receiving recess having platforms that rise from the recess to have platform top surfaces that are co-planar with the angular member top surface. The platforms provide additional support for the file with minimal reduction of recess volume and efficiency of filings removal. The ski sharpening guide preferably includes a clamp for securing the file in position relative to the guide and the ski edge.
