Hordion 4" / 10cm Fret Leveling File Sanding Fret Leveler Beam Luthier Tool for Guitar Bass

It’s great but very aggressive.Be careful to keep checking your work every few strokes.

File is warped and has come unglued from the wood block. Re-gluing would be a simple task, but the file is warped and can't be used for fret leveling. I will have to return for exchange.

Great tool for filling one fret at a time.
