Pillar Regular 2 Sides Cut.
Pillar files are parallel in width and tapered in thickness to make possible perfectly flat filing.
Pillar regular 2 sides cut files are double cut top and bottom with both edges being safe with no cut.
Glardon Vallorbe® Swiss Made Precision Files are measured from the point where the teeth begin to the end of the file.
A 6" precision file will measure 8" long from tip to end of tang, but it is called a 6" file. Remember, the higher the number the finer the cut.
