Compact Norton Knife Sharpener for All Users

The 1 x 8 x 2 inch (H x W x D) Norton 614636855653 IB8 India 100/320-grit combination oilstone is made of aluminum oxide with a 100-grit surface on one side for repairing steel cutting edges and a 320-grit surface on the opposite side for sharpening and maintaining them. This oilstone is preferred for close tolerances, as it produces durable, smooth-cutting edges. It is used to restore cutting edges on straight-edged tools, such as chisels, knives, plane blades, and precision instruments.

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 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, then molded and surface-finished.

Sharpening stones, or whetstones, are abrasive surfaces used to sharpen and hone the edges of steel cutting implements. 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, while 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, while the stone with the finest grit produces the sharpest edge.

The Norton IB8 Combination India bench oilstone is designed for efficiency in repairing and maintaining the razor-sharp edges needed for various tools, including kitchen knives, hunting knives, and more. It is more durable and harder than a waterstone, and is intended to be used with Norton Abrasives Sharpening Stone Oil for the most efficient sharpening system. The stone is prefilled with oil to allow the lubricant to stay on the sharpening stone surface while sharpening, preventing the metal and abrasive particles from embedding into the surface and keeping it free-cutting.

Norton Abrasives, now a brand of Saint-Gobain, has been manufacturing sanding, grinding, and polishing abrasives in the United States since 1885, and meets ISO 9000 and 14001 certification for quality and environmental management standards.
