Gransfors Bruk Sharpening Diamond File

The Gränsfors diamond file is a straight diamond file with a coarse side and a finer side, and features a small wooden handle. The handle is slightly wider near the file blade to give a good grip. The diamond file is normally used with water but can also be used dry. The diamond file is 230-grit on the coarser side and 400-grit on the finer side.
