Use this WÜSTHOF Classic Ikon 10" Honing Steel with Double Bolster for exceptional honing of your knives. Even high-quality knives, such as those made by WÜSTHOF, gradually dull due to use. To compensate, a honing steel should be used regularly. A few strokes of both sides of the knife over the sharpening steel will help you to maintain the sharpness of a good blade.
