They work fine and do a nice job.

I had never made this adjustment before so I was a bit skeptical that I could do it without messing it up. These files worked great and I now have a nice low action and no fret buzz. These are highly recommended.

Excellent files, worth the investment

These worked very well. I've used the nut slot files for guitar for quite some time, and I've found both sets do a great job.

I bought the 5 string set and it's genuinely a good set of files. Only complaint I had is the lightest gauge file was slightly curved when it arrived and for the price I feel like that could have been addressed. Of course it's entirely possible that I just got a bad one. Overall very happy with the purchase.

a little pricey, but when you need them,you want the good stuff.

I just love guitar tools, love to hold them and get a feel for what the tool tells me. This set spoke LOUD AND CLEAR! "Come on Rudy, USE ME!"
Talk about smooth cutting, ease of use (no more fingers falling asleep from gripping them 'just right'.
Now, they just fit into my hands and make the job of slotting a breeze! Another man-u-fique job in tool making! I am truly pleased and blessed to be a customer of Stew Mac, best Luthier suppler in the business.

Good file, easy to use. Love the labels on the side of each file

I always do my own nuts lot Heights. Finally got the correct tools for the job

Great , Smooth and precise on bone material.
Just yesterday I was slotting a 5 strings Tusq blank and I was surprised that file teeth worn very badly before even I finish the slotting job as if I was slotting a sharpening stone.
