Have Surpassed My Expectations

I have used these files now for several months to recrown multiple (100+) Stainless Steele and Gold frets without issue. I had reservations about the durability of these files but have actually found them to be very acceptable. I'm satisfied with the price also.

Gets the job done

I didn't want to spend the cash for the diamond files since I usually only work on my own instruments. These files are well made, and crown frets with little issue. I found that light pressure and many strokes worked well - it also leaves less heavy file marks on the frets. I would go this route again if I had to, but would like to compare these to the diamond files some day.

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.

Looks good!

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! ;)

Excellent Tool  for Re-Crowing Job

By Pete Davis from Brisbane, Australia

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.

Great for old divots.

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.

Best selling for a reason.

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.

This is the right tool for this job.

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

Double-edge Fret File Medium/Wide

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
