Norton 4-1/2-ounce sharpening stone oil is formulated for oilstone lubrication, with the correct viscosity for smooth sharpening without loading or clogging stones; it flushes away dislodged abrasive and metal chips to prevent metal from bonding with the surface of an oilstone, and meets U.S. Pharmacopeia standards for mineral oil purity and FDA requirements for use near food preparation. Norton sharpening stone oil is a highly refined lubricant that is effective for many other lubricating uses.

This 4-1/2-oz. can of sharpening stone oil, measuring 5 x 2 x 1 inch (H x W x D), has a snug-fitting lid, stores compactly, and fits into Norton portable sharpening systems for mobile use. (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.) This oil meets U.S. Pharmacopeia (USP) standards for mineral oil purity and U.S. Food and Drug Administration (FDA) regulations for use near food (FDA 21 CFR 178.3620).

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. When used with lubricating liquid, a sharpening stone can be called a waterstone or an oilstone, based on the lubricant required. Oilstones use sharpening stone oil for lubrication when sharpening, to prevent metal from bonding with the abrasive surface by flushing away dislodged abrasive and metal chips.
