Average
I didn't like this diamond file much,the radius doesn't seem perfect or even and it's still too coarse to my taste. I bought that file 300 grit , the similar 150 grit one and the Hosco 600 grit.The Hosco 600 grit is by far my favorite.

Sharp edges may damage finish or fretboard
The edges on either side of the diamond crown file area and the rest of the file body is a bit rough. Mine had a small sharp piece of metal sticking out which easily cut into the skin of my finger (no blood). These will need a bit of filing/smoothing before using - especially near a finished guitar body or fingerboard. The diamond surface itself seems very nice - well done.

Excellent file from the first use!
I have been using the regular Hosco fret crowning file set I purchased from Philadelphia luthier supply a number of years back. They are holding up nicely after all of these years. Recently, I decided to plunk down on the finer grit Diamond Fret Crowning File sold here and I’m glad I did. First-time use was for a stainless steel fret dressing on a 1985 Jackson USA Soloist. This file cuts very smoothy right from the get-go and will be my go-to file for stainless steel fret crownings.
