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. The silicon carbide stone used for this tool is fast-cutting and offers effective sharpening even under light pressure. It is created by grading silicon carbide to a consistent particle size and blending it with bonding agents. It is then molded and surface-finished. This 14-inch file, which is suitable for hand use, has a 9-1/8 inch oilstone blade with 1/2 inch diameter and a 4-7/8 inch wooden handle. The oilstone portion of this tool must be lubricated with oil before use, to prevent metal from bonding with the abrasive surface of the stone. It conforms to the American National Standards Institute (ANSI) abrasive grit standard. Sharpening stones, or whetstones, are abrasive surfaces used to sharpen and hone the edges of steel cutting implements, such as chisels, knives, scissors, hand scrapers, and plane blades. Sharpening is the process of creating or re-establishing a cutting edge by grinding away portions of the metal to adjust the angle of the edge and reform the shape. Honing removes small imperfections. Stones can be flat, for working flat edges, or shaped, for edges that are more complex. Sharpening stones are made of natural or synthetic materials that range from softer to harder, and are categorized by the size of their abrasive particles, known as grit. A stone with a coarser grit is used when more metal needs to be removed (e.g., when sharpening a nicked or very dull blade); the stone with t...
