From the worlds finest file makers come these Barrette Needle Files by Vallorbe in Switzerland. Sometimes referred to as a Safety Back file because they only cut on one edge, these are ideal for finishing internal angles without fear of changing any other surface. Popular with Luthier's for filing guitar fret ends without damaging the wooden finger board.
