Norton 61463687750 Utility File Sharpening Stone

The Norton 100-grit silicon carbide utility file is a long wedge-shaped oilstone with four flat faces and a wooden handle, suitable for repairing, sharpening, and maintaining coarse cutting edges; it sharpens to moderate tolerances when it is more important to sharpen the blade quickly than to produce a fine cutting edge. The hardness of silicon carbide makes it capable of longer tool life than the lifespan of a steel file. The wooden handle provides a comfortable grip and the four faces hold their shape for uniform filing. This tool is commonly used to restore cutting edges on gardening and other cutting tools.
