Over time, even the best quality sharpening steels will eventually lose their edge and need to be replaced. However, with proper care and maintenance, your steel can last for many years. To extend the life of your sharpening steel, avoid using it on extremely hard or brittle surfaces, such as ceramic cookware or glass. Also, be sure to clean the steel after each use to remove any debris that could dull the blade. With proper care, your sharpening steel will keep your knives sharp for years to come.
