You can scrape with less force against the base, which is important so as not to ruin the structure of the ski base, but also to significantly improve the workflow in the waxing booth. This tool keeps your scrapers sharp and 100% flat. Two times over the rotating blade and the blades will be like new. The tool is very stable and fits perfectly on the workbench. 220v
