Hi, I'm looking at the Stewmac Guaged Nut Slotting files
http://www.stewmac.com/shop/Tools/Sp...ing_Files.html
It seems to me that their double-edged files would produce a v-shaped slot with a rounded bottom rather than straight edges.
So, which sizes do i need. I generally use regular light guage strings; 10, 13, 17, 26, 36, 46 . Is it ok to use a bigger file or should you use a smaller one and rock the file from side to side. For example, for the .026" string, should i use a .024" or .028" file?
This is gonna cost me an arm and a leg when you add in the nut shaping files, feeler guages etc.
