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. At the junction between the side surface and the top surface is a channel that preferably runs the entire length of the angular member for collection of filings. Preferably, the top surface includes a filing-receiving recess having angled walls to create a wide inlet at the channel and a narrower outlet at the top surface rear edge. The combination of long channel and angled, wide-mouthed recess form an efficient filing-removal system which prevents filings from interfering with the sharpening of the ski edge. The ski sharpening guide preferably includes a clamp for securing the file in position relative to the guide and the ski edge. The clamp is designed with a base side wall against which the file may be pushed to aid in positioning and securing the file and preventing the file from being pushed off of the guide.
