Katana - the under string fret leveling tool

For those interested in fretwork, I’m happy to announce that I am the newest endorsee of the Katana by Rectify Master. The Katana is an understring fret leveling tool created and patented by Davide Bissoli that will allow you to level your frets easily and under string tension. He also makes other tools like the LittleBone fret crowning tool which is a really easy way to get a nice crown on the fret. I did a brief video with the Katana which you can see below. Check out the Rectify Master site and tell ‘em Sully sent ya!
