The Norton 100/320-grit combination oilstone is made of aluminum oxide with 100 grit on one face for repairing steel cutting edges and 320 grit on the opposite face for sharpening and maintaining them; it produces durable, smooth-cutting edges, and is preferred for close tolerances. The stone is prefilled with oil to save time and eliminate the need to presoak it prior to use. The oil prevents metal from bonding with the abrasive surface by flushing away dislodged abrasive and metal chips. This oilstone is commonly used to restore cutting edges on small straight-edged tools such as chisels, knives, plane blades, and precision instruments.
This aluminum oxide stone has a tough fracture- and wear-resistant grit that is more durable than silicon carbide and capable of sharpening to very close tolerances. It is created by grading aluminum oxide to a consistent particle size and blending it with bonding agents. It is then molded and surface-finished. This 1 x 6 x 2 inch (H x W x D) stone, suitable for bench use, is harder and more durable than a waterstone. (H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.) It conforms to the American National Standards Institute (ANSI) abrasive grit standards.
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.
Norton Abrasives manufactures sanding, grinding, and polishing abrasives, and has been located in the United States since 1885. Norton, now a brand of Saint-Gobain, meets ISO 9000 and 14001 certification for quality and environmental management standards.

The stone is great. It cuts well as you can feel it bites into the material. It doesn't wear out a lot so the stone geometry wont change much. I bought three of them, two of them arrive normally and i am using them happily.however, for the last one, they sent wrong item twice! i keep getting the black silicon carbide one instead of the aluminum oxide one with one side being orange. this is really annoying since i have to send it back twice for replacement and refund as well. for real amazon, check your warehouse, did you have the wrong label on tray??

La famosa pietra per affilare Norton, doppia grana, da usare con olioPerfetta, presa perchè negli anni 70/80 papà la aveva e affilava perfettamente.Purtropo non ho più ritrovato tale pietra, ma questa è esattamente come quella che ricordavoSi ottiene facilmente un filo molto tagliente, soprattutto se si usa uno strop alla fine conqualche pasta di lucidatura o anche solamente del polish ( sidol )
