ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a ski edge sharpener which provides four sharpening angles, which allows both sides of a file blade to be used for filing, which allows longitudinal sections on each side of the file blade to be used for filing, which can provide a small “bow” to the file blade for filing curved ski edges, which permits exchange of the file blade and which provides a slot for receiving filings.

The Nelson et al. U.S. Pat. No. 4,030,382 discloses a SHARPENING DEVICE FOR STEEL SKI EDGE STRIPS wherein a file blade can be bent by tightening a clamping screw to put an arc in the file blade. Also a wedge can be employed to sharpen the ski edge at an angle less than 90 °.
The MULTIPLE-ANGLE DIAMOND EDGE TOOL by Sun Valley Ski Tools is elongate and generally square in cross section with four corner extensions each having a file blade and providing with an adjacent side of the tool, four different file angles.
SUMMARY OF THE INVENTION
According to the present invention, there is provided a ski edge sharpener comprising a generally rectangular-in-cross-section elongate block or body having our elongate side surfaces, a file blade mounting plate releasably fixed to one of the elongate side surfaces and a tile blade mounted on or to the file blade mounting plate in position to engage a side edge of a ski placed on an adjacent elongate side surface of the block or body for sharpening the ski side edge at one of four angles.
