Diamond files will cut in both directions, cut faster, and don’t chatter or leave chatter marks.   

For beginners, we recommend the 300 grit diamond fret crowning file because it’s not as aggressive as the 150 grit file.

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

    Have done 3 crowning jobs with this file so far. Great file, really does significantly speed up crowning work once you get the hang of it. If you're used to unidirectional metal files, it'll take some getting used to the faster, bidirectional motion. I woul give it 5 stars, but they need to mark which side is which so you don't get them mixed up. It also needs a grab handle on the business end to allow 2-handed filing and reduce relieve hand stress. Regardless, I will be ordering the 300 grit as well.
