The acoustic diamond coated nut files from MusicNomad feature a revolutionary diamond coating and round “string-shape” blade design resulting in smooth, precision cuts. They cut and polish slots at the same time and do not drift like common toothed files. The industrial, even diamond coating cuts all nut or saddle materials, such as nylon, bone, graphite and TUSQ. MusicNomad added an ergonomic handle for total comfort and control of your cut, or you can remove the blade from the handle as an alternative cutting option. This custom set comes with 6 Nut File sizes for acoustic guitar with light/medium strings. It even comes with a compact, strong aluminum case.
