MN850 Diamond Coated, Safe Zone Guitar Fret Crowning File & Luthier Tool (S-File)

A TRUE GAME-CHANGER: Developed in partnership with leading repair technicians, the Safe Zone S-File establishes a new, higher standard for what you can anticipate from a fret crowning file. Every detail is considered, and it is filled with exceptional features and advantages. WHY DID I NOT THINK OF THE SAFE ZONE?: The patent pending Safe Zone innovation stops you from over filing. At the top of the file, a small strip contains no diamonds. Once you perfectly shape and round both sides of the frets, the S-File ceases filing and glides on top of the fret. You can hear and feel the change and it's time to proceed to the next fret. It's that simple. File-Skate-Go! The premium diamonds allow for both rapid and accurate filing. Whether you are an experienced tech or new to fret crowning, it shortens 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 enhanced the roundness of our wide channel to improve functionality. Additionally, our diamond file cuts in both directions, accelerating the process, unlike toothed files that cut in only one direction. BIG IMPROVEMENT OVER EXISTING HANDLE DESIGNS: The comfortable, heavy, ergonomic handle design makes a notable difference. It begins with an innovative blue silicone comfort grip that minimizes hand fatigue. The offset design offers added leverage when filing and enables you to clear the guitar body when filing over it. Weight makes a difference. The design is sturdy so the weight of the S-File does the work for you, 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 wear off, allowing you to know the correct file size to use. A convenient hang hole is also provided.
ADDITIONAL FEATURES & BENEFITS: It performs excellently 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 reduce its effective use duration. Stainless Steel is used on a small percentage of Electric and Bass Guitars. The exclusive nose design features two lines for spot fret crowning. Position the line to be 90 degrees from the frets and you will be filing right where the line intersects with the fret. The high quality manufacturing process includes radiused and beveled edges along the entire perimeter
