NICHOLSON - 12" KNIFE DOUBLE/SINGLE CUT BASTARD FILE WITH SAFE BACK - 07085N

The Crescent Nicholson knife-shaped files have double-cut sides with smooth coarseness for a finer finish, then single-cut teeth down the sharp side for clearing corners or acute angles. The safe back design protects the user and the object you're filing, making this a perfect tool for tool and die makers who can utilize the triangular shape.
