Works perfect. Two different angles make quick work of overhanging frets. very well made. The only change I would make is to use nylon tipped screws to hold the files. When screwing in the metal screws, the files try to twist out of position as the screws tighten down. Other than that, I am extremely pleased. Worth every bit of 5 stars! Review: Just right for the job! - Double side file included, a medium and a fine cut side. Nicely shaped wood block fits your hand, radius underside might not match every neck out there, but a lot easier to manage as opposed to flat surface which would tend to wander all over as your transverse the neck. The screws to secure file to slot in the block are in metal threaded inserts which is nice. This will get you reasonably uniform flat bevels on fret ends, to which you can further refine to your liking with hand files, rounded over, tapered, etc. Just the ticket for the fret spout which always comes along this time of year in the colder climates! (At least on instruments that haven’t been previously experienced with this) Be careful although with this item (or any time) when working on fret boards over the guitars top! EDIT 1/20/26 Another reviewer mentioned the screws biting into the file surface to hold it in place was not doing the file any favors, and I agreed with that. So, replacing the Phillips head screws with nylon tipped set screws is the cure. The set screw I used is 4mm x 8mm long (0.7mm thread pitch) 2mm hex key, overall length including the nylon tip is about 9mm. Readily available desertcart in pack of 15 for a few bucks. First photo shows both supplied screw and replacement set screw. Otherwise, this tool is a welcome addition to the shop. ## Features - Designed by our Sonoma, CA team, we worked with top repair shops around the country to determine the perfect angle for beveling fret ends. Dealing with fret sprout or after installing new frets, the 23° angle provides the ideal bevel on frets for all styles of playing. Use the 3° angle for initial filing, fret sprout, flush filing or tang removal. - Fully adjustable 6” (15cm) file with a 2 ‘n 1 design that allows you to easily change between file finish, bevel angle degree, and is replaceable. One file side is Double Cut for heavy removal and a coarse cut with the other side of the file is Single Cut for fine removal and a smooth cut. The perfect 1-2 combination works for all fret wire types including nickel silver, EVO gold and stainless steel and helps get it primed for the next step, a fret dressing and polish. - Our innovative handle design includes a curved radius underside that is wide enough to cover the entire fretboard and keep you centered while filing, providing consistent results across the entire fretboard. - No detail is overlooked, the high carbon-steel file is treated with anti-rust coating and all 4 edges are polished smooth to protect your prized instrument. Our deeper channel recesses the file to clear the body when filing fret ends on acoustic guitars. - Made of high quality Acacia hardwood that is durable and long-lasting and is ergonomically designed to give you comfort and control when filing. We even include a convenient hang hole. ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #6,128 in Musical Instruments ( See Top 100 in Musical Instruments ) #115 in Guitar Tools | | Customer Reviews | 4.6 out of 5 stars 252 Reviews | ## Images ![Precision Fret Beveling File (B-File) (MN831) - Image 1](https://m.media-amazon.com/images/I/81eE163OH-L.jpg) ![Precision Fret Beveling File (B-File) (MN831) - Image 2](https://m.media-amazon.com/images/I/81tp3tESEAL.jpg) ![Precision Fret Beveling File (B-File) (MN831) - Image 3](https://m.media-amazon.com/images/I/71J6Uf3FASL.jpg) ![Precision Fret Beveling File (B-File) (MN831) - Image 4](https://m.media-amazon.com/images/I/71pCF3O8L3L.jpg) ![Precision Fret Beveling File (B-File) (MN831) - Image 5](https://m.media-amazon.com/images/I/81+qKsRUP1L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Get rid of those cheese grater fret ends! *by E***1 on August 7, 2026* What an awesome tool for beveling fret ends.
