The Professional Way To Safely Widen Or Cut New Dovetails
Specially manufactured, true parallel, 3-square file with only one side cutting - other two sides safe. This means the file can be used to widen dovetail slots in gun barrels without danger of deepening the slot or damaging the edge not being worked on. Being a true parallel file, you have absolute control over the angle of the dovetail - impossible with other type files.
