Works on stainless frets, too!
All of our tools are suitable for use on stainless-steel fretwire, with the exception of our Fret Tang Nippers and Fret Cutters. Modern stainless-steel fretwire is known to be harder than the traditional nickel-silver blends, but our own shop experience indicates the wire does not cause premature wear of files or sandpapers.

Used this tool about five times, the files wouldn't stay in tight. not easy to get accurate results. sits in the bottom drawer of my tool box, ( would throw away but I'm a pack rat)

Save up for the Diamond Versions!

These don't cut anywhere near as good as the regular double-edged crowning-file.

If you need this shape handle for clearance, save up for the diamond ones!

A fair tool

By Tadej from Slovenia

It does the job as described. Put that aside, for the price you pay the shaft should be stainless hardened steel, glued to the handle and coated with a clear finish at least, come on guys, mine had patina out of the box and I had to glue the handle. I know the actual burrs are the most expensive to manufacture and I really hope they are HSS. And instead of encouraging people to buy awfully expensive diamond files for SS jobs, I'd encourage good folks at Stew Mac to redesign the Gurian file and make something like tungsten burrs in extra fine single-cut grit. All in all, thank you for the deal, I must admist it's a bit pricey, but then again the Gurian is rather rare. Thanks.

Nice, but a bit pricey

My first time doing a crowning job and took a chance to use this product. The job came out great and the files were easy to use ( along with the gaurds of coarse ).

I like it very much

Yes, i like it, but can't use it very often cause i usually do refrets with very wide wire that oversizes the file, but in normal wire, i love it.

An OK Tool

By Bill in GB from WI
(Customer's Reviews) Thursday, April 05, 2012

I bought this to do the frets on a cheap classical guitar just to see what would happen. I didn't want to spend too much in case I turned out to be lousy at it. The tool worked OK kind of a rough feel in use. I think it left the frets a little flat. But the job turned out pretty good. after leveling,using the fret file, and polishing the action on the guitar was actually pretty amazing. I would say this is a good tool to try to see if you can do a fair job and then buy some better files if it turns out good. Which is what I'm going to do before I tackle my "good" instruments.
