This is a better tip cleaning set than most, the files are a bit shorter than some but seem to be a little sturdier making them better for rounding the bottom of guitar nut slots. Tip: buy yourself at least 3 actual nut files for the thinnest string gauge slots and then a set of micro files for the larger gauge string slots and a set of these to round the bottoms to remove file burrs that keep the strings from laying solidly in the slots and cause string fuzz and buzz you know that sitar sound that has you baffled on that one string, these will cure that problem, they round the bottom of the string slot way better than Stew Mac's gauged nut files do.
