When we're asked to recommend just one fret file, it's gotta be the 3-in-1. It's been popular since master luthier Michael Gurian designed it over 20 years ago. The angle in the shaft lifts the handle up away from the guitar, protecting the top. Since it has 3 interchangeable cutters it works for all fret widths, from basses to mandolins.
Steel shank, wooden handle. Overall length is 7" (178mm). Each burr is 1-7/8" (47.63mm) long. Works on stainless frets, too!
