Maxparts SF-046 Nut File 046

This is my second type of nut files that I bought. The first one was Göldo Double Edge Nut File which turned out a straight edge like this |_|, which is not the preferred bottom for the string to lie in.

Maxparts SF series nut files are with U type edge on both narrow sides and flat no grinding surface on the sides. You will need also a V-shaped little file to form good groove for the strings.

it is really good for the job, but expensive. i only used it twice. only time will tell for the overall quality/value rate

File works well and aligns es well with 10s and 10.5 strings. No issues. But you need to know what you are doing.
