Barrette Files are tapered in width and tapered in thickness, coming to a rounded point at the end. Only the flat side of the barrette file is cut, leaving a safe edge and top. Measurements given are at the thickest point of the file.
Glardon-Vallorbe Swiss-Made Valtitan Pillar Files Identified with yellow painted tangs, Valtitan files are specially treated to increase their hardness to 72HRc on the Rockwell scale, the hardest steel file known. The special Valtitan file delivers better performance on hard to file surfaces and makes these files corrosion resistant as well as longer lasting. Valtitan files also resist metal accumulation in the teeth of the file, as a simple knock is usually enough to remove the chips. Valtitan files are recommended for platinum work and for other hard metals like stainless steel, but they work great with all metals.
