Say no to black markers, constantly checking and worrying about overfiling, MusicNomad takes fret crowning to the next level with the game-changing Safe Zone "S-File." It's packed with too many unmatched features and benefits to list here, but it starts with MusicNomad's safe zone innovation that has no diamond grit at the top of the arch of the channel, eliminating the chance of overfiling. Their Safe Zone filing design reduces the fret crowning learning curve from weeks to hours. Premium 240 diamond grit combined with the ideal filing radius design gives you the perfect cut every time.

Next, there's the inventive blue silicone comfort grip, a breakthrough that reduces hand fatigue like no other. The offset design provides both added leverage when filing and allows you to clear the guitar body when filing over it. It works amazing for crowning the most popular and widely used fret wire material, nickel silver, found on all acoustic guitars, banjos, ukuleles, and most electric and bass guitars. As with any file, using it on stainless steel fret wire will shorten the file life. Stainless steel is used on a small percentage of electric and bass guitars. Be sure to check the manufacturer's fret specification before using it on your instrument.

The S-File works on all fret sizes, has custom lines on the nose for spot crowning, a wide channel that is not too flat, a common complaint of other crowning files, a convenient hang hole, and so much more. MusicNomad's exclusive nose design features two lines for spot fret crowning. Position the line to be 90 degrees(straight up) from the frets and you will just be filing right where the line intersects with the fret. It's so simple but functional. 

Don't lose or loan your S-File. You'll look forward to the next time you crown your frets. That's MusicNomad quality, bringing fret care to the next level.
