Crescent Nicholson 21701NN File, Flat, Rectangular Profile, American Mill Pattern, Bastard, Single Cut, 10 in L Blade

The Crescent Nicholson single-cut bastard mill files sharpen mill or circular saws and are ideal for draw filing and finishing metals. The rectangular shape lets you smooth and sharpen straight surfaces. 2 square edges allow you to make grooves fixed at the same width as the file and all sizes taper slightly in width to improve access in slots.
