Abrasive sharpening stones are used to sharpen the edges of metal cutting tools and debur, clean, and smooth workpieces or surfaces. Also known as a whetstone or water stone, a sharpening stone's shape determines its use, and its surface material and grit size determine the finish it provides. Slim sharpening files debur and chamfer hard-to-reach areas of machine parts and tools. Flat, rectangular sharpening stones hone sharp edges on chisels, knives, and razors.
