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.
