Anyone who has tuned skis can tell you that scraping the wax is the most time-consuming and tedious task of the process, and lacking a sharp plastic scraper makes it that much more onerous. With the Swix World Cup Scraper Sharpener, you'll never lack a sharp scraper again. Swix built this scraper with two vertical walls to ensure a clean 90° edge every time. With a 100mm long file that can be replaced, Swix has delivered the last sharpener you'll ever need to buy.
Have had one of these through an entire ski racing career and it will remain in my box/on the bench for the rest of time. Never once had an issue with it and provides a reliably sharp scraper every time. Occasionally take the file out to get it cleaned off and that's all the maintenance you'll need to do. Lot of people tend to screw it to the bench, I like to be able to keep it loose so you can hold it while using it.
