The Toko DMT Diamond File is the final step in tuning your edges. It‘s also effective for a de-burring job after using a machine or stone grinder. The Toko DMT Diamond File is designed to fit into Toko edging fixtures as well, so you can upgrade your existing pro setup. Sharp edges are your friends out on the hardpack, so make sure your tuning is diamond quality. The course file quickly removes any edge burrs from skiing over rocks and the fine file works better with Toko tools for sharpening your edges.
