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 the finest grit produces the sharpest edge. Where numbers are assigned to specify grit, they range from coarser grit (low) to finer grit (high). Some sharpening stones are designed for use with a lubricating liquid, some can be used dry, and others can be used either wet or dry. When used with lubricating liquid, a sharpening stone can be called a waterstone or an oilstone, based on the lubricant required.

I have the 8" bench stone and always find myself standing it up while lapping rough glass so when I found this file I was thrilled. The handle is hefty and matches the weight of the stone. The coarse grit glides through material quickly and evenly. I bought a second file for back up.

I needed a file to sharpen smaller instruments, and this was awkward for me to use but it did get the job done. Just be prepared to figure out where to store it.

It's work nice like every norton coarse pike stone. Easy to unscrew the wood handle to use it like a regular bench stone.

I bought this due to a suggestion in Popular Mechanics magazine article. It seemed perfect for sharpening things on the job site or in remote locations where you don't have all your normal tools or electricity, etc. I noticed some complaints about it. I don't have any of those issues with it. To test it I sharpened my lawn mower blade. It did the job. Obviously a bit more work than an electric grinder wheel. I was doing it to test the feasibility. I believe it will work in all those odd cases. It is small enough to fit in your tool bag and use in those just in case times.
