The MusicNomad Safe Zone S-File is a diamond crowning file for guitar, bass, banjo and ukulele frets. Its key feature is a channel with no diamond grit at the top of the arch, which stops you from overfiling and flattens the crowning learning curve. The 240-grit diamond surface and offset blue silicone grip add control and reduce hand fatigue. It suits players and techs doing their own fret level and crown work on nickel silver wire; on stainless steel it wears faster, so check the fret spec first.

Owners and reviewers treat the Safe Zone design as the file's main draw, saying the grit-free top makes crowning hard to get wrong. The comfort grip and offset shape get consistent praise for control. The main caveat raised is wear on stainless steel frets.
The MusicNomad Safe Zone S-File is a diamond-coated fret crowning file. Its channel has no diamond grit at the top of the arch, a "safe zone" that eliminates the chance of overfiling. The file uses 240 diamond grit and a filing radius designed to give a clean cut.
It has a blue silicone comfort grip to reduce hand fatigue. The offset design adds leverage when filing and lets the file clear the guitar body when working over it. The channel is wide and not too flat, and the file includes a hang hole.
The nose has two lines for spot crowning. Position a line 90 degrees (straight up) from the frets, and the file works only where the line intersects the fret. The S-File works on all fret sizes. It suits nickel silver fret wire, found on all acoustic guitars, banjos and ukuleles, and on most electric and bass guitars. Using it on stainless steel fret wire shortens the file's life. Check the manufacturer's fret specification before use.
