Gransfors Bruk Axe File
This axe file is a fine-toothed iron file with two faces and a small wooden handle used to remove big burrs or indentations from the axe blade. The handle is thicker near the file blade to give a good grip. The file has a coarse side and a fine side.
The file is designed with grooves (roughly 20 per centimetre), which corresponds to approximately Standard DIN 8349
