Diamond Coated Guitar Fret Crowning File (S-File)

The Innovative Safe Zone Guitar Fret Crowning File (S-File) by MusicNomad: A Game-Changer in Fret Care

MusicNomad's Safe Zone "S-File" takes fret crowning to the next level, eliminating the risk of overfiling and reducing the learning curve from weeks to hours. Designed by the Sonoma, CA team in collaboration with top repair technicians, this diamond-coated file is packed with unmatched features and benefits.

The patent-pending Safe Zone innovation is the key to the S-File's success. At the top of the file, a small strip without diamonds prevents you from overfiling the frets. Once you've perfectly sculpted and rounded both sides of the frets, the file stops cutting and simply skates on top, letting you know it's time to move to the next fret.

The premium 240-grit diamond coating is precisely rounded to match the original radius of your frets. One channel is designed for narrow/medium frets, while the other handles wide/jumbo frets. The diamond file cuts in both directions, speeding up the process compared to toothed files that only cut one way.

The ergonomic, silicone-lined handle enhances comfort and control during fret crowning. The offset design provides added leverage and clears your hand when filing over the guitar body. Weighing in at a hefty 0.38 lbs (173g), the S-File is in a weight class of its own, allowing the tool to do the work for you.

The S-File works amazingly well on the most popular fret wire material, Nickel Silver, found on acoustic guitars, banjos, ukuleles, and most electric and bass guitars. While using it on stainless steel frets will shorten the file's lifespan, the exclusive nose design with two lines makes spot fret crowning a breeze. Simply position the line 90 degrees from the frets, and you'll be filing right where it intersects.

MusicNomad's commitment to quality extends to the high-end manufacturing process, which includes radiused and beveled edges along the entire perimeter.

In addition to the game-changing S-File, MusicNomad offers a full range of Next Level Fret Care products, from the innovative Fret Shield to the ergonomic Fret Leveling Beams. With a focus on giving back to the music community, MusicNomad is a brand you can feel good about supporting.
