This rod sharpener is made of stainless steel. Honing steels are designed to be used often, but without taking off too much of your knife’s edge metal. This is contrary to knife sharpening steels or wet stone sharpeners, which should be used sparingly. Ergonomic easy-to-grip polypropylene handle, aesthetic and practical, giving you higher efficient sharpening experience. Metal hanging ring provides a simple wall-mounted storage. Use a non-woven cloth soaked with cooking oil to wipe the Sharpening and dry it. If washed with water, be sure to wipe the rod dry completely after washing and hang in a cool place to air-dry. Do not put the Hong Steel into the dishwasher.
