Lee Valley Hiroshima Yasuri Fret Files

Made in Japan by a company that has been manufacturing files for 80 years and guitar files for three decades, these are the best on the market for sharpness, regularity of cut, and durability.

Used to re-crown frets after dressing them to the same height, these files have concave edges to apply a smooth curve, ready for polishing. Each double-edged file has the same groove diameter on both edges, with smooth surfaces on either side of the groove to avoid marring the fretboard.

Sized to match common fret widths, all are 8 3/4″ long overall with a 3 7/8″ cut length; channel diameters are listed.
