Richardson Sheffield Cucina Sharpening Steel

Position the steel vertically with the handle upright, hold securely over a wooden / plastic cutting board or other suitable surface, such as a tea towel. Knives are sharpened to approximately a 20° angle. To find this angle, first hold the knife at a 90° angle to the steel, then visually cut this angle in half, moving to a 45° angle. Finally half it again to find an approximate angle of 20°.
