  • A TRUE GAME-CHANGER: Designed by our Sonoma, CA team and in collaboration with top repair techs, the Safe Zone S-File sets a new higher standard for what you should expect when you buy a Fret Crowing File. No detail is overlooked, and it is packed with unmatched features and benefits.
  • WHY DID I NOT THINK OF THE SAFE ZONE?: The patent pending Safe Zone innovation prevents you from over filing. At the top of the file, there is a small strip where there are no diamonds. Once you perfectly sculpt and round both sides of the frets, the S-File stops filing and skates on top of the fret. You can hear and feel the difference and it's time to move to the next fret. It's that simple...File-Skate-Go! The premium diamonds make both fast and precision filing. Whether you are a seasoned tech or new to fret crowing it reduces the learning curve from weeks to hours.
  • THE PERFECT DIAMOND FILE DESIGN: The 240 grit premium diamond coating is perfectly rounded to closely match the original radius of your frets. One channel is for narrow/medium frets and the other is for wide/jumbo frets. After hearing many repair shops complain the wide side of existing files are too flat to use, we increased the roundness of our wide channel to improve the functionality. Additionally, our diamond file cuts in both directions, speeding up the process, unlike toothed files that cut in only one direction.
  • BIG IMPROVEMENT OVER EXISTING HANDLE DESIGNS: Our comfortable, heavy, ergonomic handle design makes such a big difference. It starts with our innovative blue silicone comfort grip that reduces hand fatigue. The offset design provides both added leverage when filing and allows you to clear the guitar body when filing over it. Weight makes a difference. We beefed up our design so the weight of the S-File does the work for you and is in a weight class by itself at .38 lbs (173g). Lastly, the fret size channel application is engraved in the handle so it won't rub off, allowing you to know the correct file size to use. We even include a convenient hang hole.
  • ADDITIONAL FEATURES & BENEFITS: It works amazing for crowning the most popular & widely used fret wire material, Nickel Silver, found on all Acoustic Guitars, Banjos, Ukuleles and most Electric & Bass Guitars. As with any file, using on Stainless Steel fret wire will shorten the file life. Stainless Steel is used on a small percentage of Electric and Bass Guitars. Our exclusive nose design features two lines for spot fret crowning. Position the line to be 90 degrees from the frets and you will just be filing right where the line intersects with the fret. Our high quality manufacturing process includes radiused & beveled edges along the entire perimeter.
