Signature Sharpening steel, 23cm from English Robert Welch. Sharpening steel in a classic design that ensures that all your knife walls are in perfect condition. The primary function of the sharpening steel is not to sharpen the knives but to straighten the edge, which after a period of use is folded in one direction due to wear. Like the knives in the Signature series, the sharpening steel is equipped with an ergonomic DuPont handle. Can be washed in the dishwasher.
