Abstract: The diamond tipped nut filing tool includes a body and a diamond tipped file. The diamond tipped file may be disposed along one end of the body. The body has a longitudinal length and at least half of the length includes a circumference so that at least one half of the longitudinal length is rounded.

Abstract: A stringed instrument fret filing tool and a method of making the fret filing tool. The fret filing tool includes a body having more than one major surface and numerous minor surfaces that defines a substantially planar profile. The planar profile is sized to a length that engages with three frets on a fretboard of a stringed instrument. Each of the minor surfaces defines a different length than the other minor surfaces. A file is formed on a middle portion along each of the lengths of the minor surfaces and opposing end portions are formed on the length of each minor surface and are disposed astride the file. During use of the fret filing tool, the file may glide along a raised fret and file the raised fret until it is the same height as the adjacent frets.
