Double-edge Fret File

I've only used the small side, but it works good, I'm sure the other bigger side works as well. Gives you what you need for forming a good crown.

If you need to do a fret job on anything but a John Deere tractor, you gotta have one of these fret files. I know I tried, and it wasn't pretty. They're high quality and easy to use. Little spendy but worth the investment!

I bought this file to recrown the frets on my Epi Les Paul. Overall, I think it worked good. I just needed to polish some frets after recrowning them to get rid of a few harsh file marks. But i think this was my fault, cause it's the first time i have done it! Thumbs up for stewmac! ;)

I bought this file to re-crown a 25 year-old Hamer whose frets were worn fairly flat in a lot of places. After leveling and re-crowning with this file, the guitar plays like new. Absolutely great tool for the job.

Recently ordered the Narrow/Med fret file to re-crown a Gibson ES-137.
I bought the guitar secondhand from a store and felt that the previous owner had traded it because the frets were like railroad sleepers (square profile).
I was told like many people, just get use to it and play with a softer feel!
I read about this issue on a number of online forums and decided to order the file from Stew Mac and give it a go. I followed Dan's tips and marked each fret with a felt tip pen and masked the board with Stew Mac thick paper tape before I started. I carefully recut each fret profile where it had been removed at the factory and then finished off with the Stew Mac sanding stick with a couple of grades of belt and then a final polish. Let me say, the tools worked a treat and the instrument has been transformed from a real handful to a pleasure to play.
I followed another tip and put a piece of tape over the top of the file to rest my finger and used it to control the pressure of each strokes. I following the fret radius and watching the width of my felt tip mark slowly reduce as the profile slowly reappeared. Very pleased with the result, thanks Stew Mac.

I'm a beginner with luthiery, and I get my experience with abused and neglected guitars I find at garage sales and estate sales. Fret grooves are common problems, and the Double-edge Fret File is a great piece of rescue equipment for this problem. In most cases, you can quickly remove grooves, restore a proper fret profile and produce noticeably better sounding notes from what used to be a "trouble spot" or "dead spot".

If you like rescuing old beaters and giving them another shot at life, this is standard rescue equipment. Highly recommended.

We used this tool after the radius sanding block showed us where the highs and lows of the frets were. This file, while is not instantaneous, removed some bad divots and leveled the frets to a good position.

The neck we used was on an old blank that had been used on an old electric Hagstrom (fretted, of course,) and this is a great tool. I also highly recommend the Dan Erlewine Nut Making and Fretting and Advanced Fretting Videos.

Unless you go to diamond at much greater price, I cannot imagine a more effective file than this for removing fret material to a good profile.

There is only one way to get the frets rounded after you level them off.

Don't let the price scare you away because this file worth the money you are paying for it. The teeth are spaced very nicely together giving you a smooth cut unlike some other files. I like the handle very much it doesn't slip from my sweaty hands. Handle could be a tad longer but its no big issue
