Sharpener for ski waxing scrapers similar to the small Toko one. It has 3, 4, 5 and 7-mm slots for different thicknesses of scrapers.

You will need a plane blade as the sharpening tool. I used a Rali 48mm blade that I could find in a local hardware store (see photo). If you find a different blade, you will need to adapt the design; however, it should be relatively simple from the FreeCAD source.

To use, insert the scraper in the appropriate slot and let the tool run along its length.
