Music Nomad’s Nut Files feature a diamond coating and round string-shape blade design resulting in smooth, precision cuts. This set cuts and polishes slots at the same time and doesn’t drift like common-toothed files. It cuts and polishes the most common nut materials such as nylon, bone, graphite, Tusq and even works on saddles. An ergonomic handle is added for total comfort and control of the cut or users can remove the blade from the handle as an alternative cutting option. This custom set comes with five nut file sizes for bass guitar and a aluminum case.
