A sharpening steel is a tool used to maintain the edge of a knife. It is typically a long, slender rod made of steel or ceramic, designed to realign the microscopic teeth on a knife's blade. Regular use of a sharpening steel can help keep knives sharp between more intensive sharpening sessions. To use a sharpening steel, hold it vertically and glide the knife blade along the rod at a consistent angle, usually around 20 degrees. This process helps to straighten the blade's edge, making cutting tasks easier and safer. Sharpening steels are commonly found in kitchens and are essential for chefs and home cooks alike.
