MusicNomad MN661 Diamond Coated Nut File - .056”

This patented file features cutting blades with a special industrial diamond coating that accurately matches the real shape of the string.

This ensures truly easy sharpening and precise grooves that no longer require final polishing. The file is suitable for all traditional materials such as nylon, plastic, bone, graphite, and TUSQ, but can also be used for sharpening bridge saddles. The blade is set in an ergonomic handle, which can be easily removed if necessary.
