Shapes the sides of the frets. This unique fret file lays flat on the fretboard to shape frets from the sides.

Quarter-round concave filing surfaces are at each edge of this unique fret file. The smooth flat underside minimizes fretboard marring while rounding the fret ends.

Each smooth-cut filing surface is 4-1/2" long and extends approximately .080" above the fretboard. The file is 3/8" wide, and is fitted with a turned hardwood handle and brass ferrule.

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.

Great File!

By A Jeffcote from South Texas

Good file. I must first state that my experience is limited in fret-work. I'm just now getting comfortable with it. Have 3 crowning files. The medium triangular file, a double sided non-diamond file and the quarter round. I haven't got the hang of crowning with the triangular file yet, but I can see that file being great once I get the feel for it. The double sided file shapes the fret very easily, but since I can't see the top of the fret all the time while using it, I tend to be less accurate and sometimes take too much off. Do that one time, get that one fret too low, and you have to start all over. The quarter round file is very easily controlled just by leaning it into the fret to varying degrees, so I can control the shape more than with the double sided one, not as much as the triangular one. Of course I can see what I'm doing at all times and it works great for rounding the ends also. Should have bought this one first, because it may be the last I need to buy. Used it last on this parts-caster build. Sonic Blue nitro!

Amazing tool for rounding fret ends. I've own all and tried most other files for rounding ends. This one is the best by far!

The descriptions states "it lays flat on the fingerboard" if I do that it does not touch the frets. I have to stand it on edge.

Quarter round worth several bucks at least!

Great tool for its designated purpose! Does exactly what is advertised and does it well.

Good tool, a little bit crude for the price

Its a fine useful tool, altough the handle is finely crafted, with brass crown and classic look, the file itself looks like those inexpensive asian tools. I made mine a "Five Star" with two touches: I finished the handle with tru-oil (gun stock finish) and I mirror-polished the face in the file, now I can work bound necks as well.

good stuff!!

I would have given this one a 5, but it had no instructions or demonstrations. I finally found a way to use it and it saved me a lot of time. I was laying it down instead of standing it up.... if that makes any sense.

This file is very useful especially if the fret has been leveled fairly flat. This shapes it up quick and enables you to get a diamond file around it. Works very well on jumbo frets and cuts great!

This file wont mark the fingerboard unless your are careless. I feel it works best when used in conjunction with the double edge fret file.
