Or just several grades of sandpaper and a flat surface like a piece of glass. (A mouse pad works well for getting a convex surface.) Cheaper, and less chance of overheating the metal if you’re inexperienced or unobservant (like me).
I love Bahco tools. I have a Bahco saw, a Bahco scraper, and two sets of Bahco screwdrivers (best I’ve ever owned). Pity that Snap-On bought them.
