ALS #5001 Guitar Nut File Set by Uo-Chikyu Hiroshima - 8 piece double-sided 10-56

These are very high quality but you pay for them. Good size for guitar and acoustic. A must if you do nuts out of tub or bone

Have only used once but they work as expected.

These nut files are terrible. I wasn't even able to work on one nut without EACH file going dull. I'm so pissed off. These cost a lot of money and they are useless. I wish I would've found out sooner so I could return them. Don't make the same mistake I made. Buy from Stewmac.

These files went dull after one use. Waste of money. I used them on a graph tech nut.
