Hiroshima Nut File Sets

These are the world's finest nut files and are used by most professional luthiers and guitar technicians. They are made in Japan from hardened stainless steel and are double-sided for a long lifetime of use. Nut files are used for cutting or adjusting the slots in the nuts of guitars and basses. Just choose the gauge that matches the string and cut the groove. If the string is bigger than the file, the file can be rocked from side to side to widen the slot slightly. The files are available in a set for basses and two different sets for guitars. Both sets can be used for acoustic or electric guitars but the 4050 set is more convenient for electric guitar strings and the 5001 is more convenient for acoustics. - Uo-Chikyu Hiroshima brand - Made in Japan - Professional quality - Double sided - Half-round edge profile - 115mm (4 1/2") cutting length - Hardened stainless steel tool 4050 Guitar set gauges - .010" .013" .017" .024" 0.32" .036" .040" .050" 5001 Guitar set gauges - .010" .013" .017" .024" 0.32" .036" .046" .056" 5004 Bass set gauges - .050" .058" .062" .078" .093" .109" .125"
