An oil stone is a type of sharpening stone used to sharpen the edges of cutting tools such as knives, chisels, and razors. It's called an oil stone because it's typically lubricated with oil, which helps to float away metal particles and keeps the surface of the stone clean. Oil stones come in various types, including natural stones like Arkansas stones and synthetic stones made from aluminum oxide or silicon carbide. They vary in grit size, which determines how coarse or fine the sharpening surface is. Coarser grit stones are used for initial sharpening, while finer grit stones are used for honing and refining the edge.
