These files are just about my favorite fret crowning tools, and a great compliment to my triangular files!

I still wonder how I crowned my frets before. Exellent tool.

Great shaping file

Works great for rough fret shaping after leveling. Holding up well on both nickel and stainless steel fret jobs.

Perfect weight

Not so heavy that it over cuts, not so light that it takes too much pressure. Nicely done.

This is a good file for removing material fast. But it is a relatively coarse cut file, and leaves chatter marks. I can't think of many situations where you would need a file this aggressive on frets.

Good stuff

It takes some time to master the crowning with it.

Didn't work well for me :(

I love everything I've purchased from StewMac so far but I couldn't get these to work for me no matter which size I used, how hard or light I pressed, or how fast or slow I went. They chewed the fret wire up terribly and it took some time and work to get the deep lines they gouged into the them out and get them smooth again.

Love this file. Take little effort and does a fine job. Very few chatter marks.

Need little pressure for truing frets and the grade choices/switches are simple and easy to use
