MusicNomad’s patent pending Nut Files feature a revolutionary diamond coating & round “string-shape” blade design resulting in smooth, precision cuts. They cut & polish slots at the same time & do not drift like common toothed files. The industrial, even diamond coating cuts & polishes all the most common nut materials such as nylon, bone, graphite & TUSQ. They even work amazing on saddles. We added an ergonomic handle for total comfort & control of your cut, or you can remove the blade from the handle as an alternative cutting option. This custom set comes with 5 Nut File sizes for Basses. We even include a compact, strong aluminum case. That’s MusicNomad quality – raising the bar in equipment care.
