Product Description

The Norton economy 100/320-grit combination tool and knife abrasive sharpener is an oilstone 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. Its compactness makes easily portable. This combination oilstone is used to restore cutting edges on flat-bladed tools, household utensils, and knives.

This aluminum oxide stone must be lubricated with oil before use, to prevent metal from bonding with the abrasive surface of the stone. The 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. An economical grade of aluminum oxide is used for this stone to accommodate lower costs and lower-usage applications. This 3/4 x 6 x 2 inch (H x W x D) oilstone, which is 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 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.
