great file

I had purchased several in the past. Thought I could get away with half of a set. I now have the whole acoustic set. Should have purchased the set to begin with.

Works great!

These work very well for what I need to do...I have about 12 of them now!

Used them to cut slots deeper in a bone nut. Cut very well. Leaves nice rounded bottom in the slots. Don't push down hard on it; let the tool do the work; just like my dad said.

I purchased this slotting file to extend the range of the guitar nut slotting set. These slotting files go through bone like butter. Great quality, and StewMac never fails to impress with customer service and prompt shipping.

I added this and 6 other sizes to my nut slotting file collection. All of this series have vertical sides, which make a nut slot that has straight, parallel side walls. The base of the slot is rounded on the thicker sizes, but not so much on the very thin sizes. I prefer my slot to be Vee shaped with a radius at the bottom. Using these files, the sides of the slots have to be tapered with another file or other too.

Paid a so-called "luthier" big money to lower the action several years ago and really didn't notice much of a difference. Bought these files, watched a few videos and 2 hours later after minimal effort the action was better than I ever would have ever imagined!

An unexpected, but a much-welcomed side effect is that the guitar's intonation problems were also resolved! Yeah!!!!

I've toyed with other ways of trying to cut nut slots and you can get close.... but if close enough
isn't good enough, then just bite the bullet and get the right tool for the job. I just used these on my
new Tele and they work perfectly!
