The Hyper Tough 8-Inch Mill Bastard File is a single-cut steel file with a soft rubber grip, sized for shaping and sharpening metal edges. The mill bastard cut removes metal at a moderate rate and leaves a smoother finish than a coarse file, so it works for saw teeth, knives, axes and deburring flat or curved surfaces. It is a basic, low-cost hand tool rather than a precision file, and it suits occasional sharpening and general shop work more than fine toolmaking.
