Our fret levelling files are flat Diamond Files designed to be guided along the fretboard with the file cutting a level onto the tops, or crown, of the frets.

Fine Diamond files,  which consist a coating of industrial diamonds embedded in a flat metal surface, give an extremely smooth finish and also have the advantage that they cut equally well in any direction of travel. This allows a back and forth motion to concentrate the abrasion on a particular area and keep the file always in contact with the fret, which helps achieve better accuracy of cut.
