Honing stones are tools used to sharpen and refine the edges of blades, such as knives and chisels. They are typically made from materials like alumina, silicon carbide, or diamond, and come in various grits, which determine how coarse or fine the stone is. The process of honing helps maintain a sharp edge, improving cutting performance and prolonging the life of the tool. These stones are often used in conjunction with a honing guide, which helps maintain the correct angle while sharpening. Regular honing can be done at home, making it a practical skill for anyone who uses cutting tools regularly.
