Fret End FileType: toolA specialized file for beveling and smoothing fret ends flush with the fretboard edge for comfortable playability.## Description A fret end file (also called a fret end dressing file or fret bevel file) is a fine-cut flat file with a safe edge (uncut side) that allows filing fret ends without scratching the fretboard surface. Some fret end files have a concave profile for simultaneously rounding the fret end while beveling. They are typically 4 to 6 inches long and narrow enough to work between frets.

The fret end file is used to bevel the fret ends at approximately 35 degrees, then smooth and round them so the player's hand glides smoothly along the neck. This is one of the final operations in fretwork and directly affects playability. Each fret end is filed individually, with particular attention to consistency across all frets on both sides of the neck. ## Selection Guide Stew-Mac fret end dressing files are purpose-built for this task and work well. A small, fine-cut mill file with one safe edge can also be used. Diamond fret end files from Hosco offer long life and consistent cutting. The file must be fine enough to leave a smooth surface without deep scratches. Budget 15 to 40 dollars. ## Tips - File at a consistent 35-degree angle on all frets for a uniform look and feel. - Use the safe edge against the fretboard to avoid scratching the wo…
