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! ### ⭐⭐⭐⭐⭐ Just right for the job! *by on Reviewed in the United States December 13, 2025* 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 1/20/26Another 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 Amazon 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. ### ⭐⭐⭐⭐⭐ Great Fret Maintenance Tool *by on Reviewed in the United States February 16, 2025* Picked this up to trim fret ends to file down fret sprout that occurred as result of seasonal change. Worked great - no damage to side of fretboard. Good weight for smooth movement up and down fretboard. I was even able to use it with strings on. Good value, ease of use and quality. If you own several guitars, a must have in the toolbox👍. ## Frequently Bought Together - MusicNomad MN831 Precision Fret Beveling File (B-File) - MusicNomad MN830 Diamond Coated E, Luthier & Tech Tool Guitar Fret End Dressing File - MusicNomad MN850 Diamond Coated, Safe Zone Guitar Fret Crowning File & Luthier Tool (S-File) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/552756348-precision-fret-beveling-file-b-file](https://www.desertcart.jp/products/552756348-precision-fret-beveling-file-b-file) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-24*
