3-in-1 fret bevel file with 3 angles: 3°, 23°, and 35°. It is designed to remove fret sprouts and burrs. To protect the fingerboard, place a layer of textured paper on the fretboard before use. Instructions for use: Choose an angle and tighten the two screws. First use the 3° angle for filing, fret budding, flush filing, or tang removal. Then switch to the 23° angle for secondary grinding. If a more beveled edge is needed, use the 35° angle for grinding. Luthier tool: Made of high carbon steel with dual-side high-precision serrated teeth. Effectively removes fret burrs and fret sprouts. Widely applicable: The Fret End Dressing File is developed to polish the fret ends and works on all frets. Suitable for guitar, bass, electric pianos, ukuleles, banjos, and so on. Use scenarios: - After fret installation, remove burrs and set clean edges on all frets. - During maintenance, refine and bevel fret ends for smoother playability. - When preparing a fretboard for binding or leveling, trim sprouts and burrs quickly without damaging the fingerboard.
