Wusthof’s Classic Ikon 10” honing steel with double bolster offers exceptional honing of your knives. Even high-quality knives such as Wusthof gradually dull due to use. Using a honing steel regularly will compensate for this, as it will realign the edge of your knife. A few strokes of both sides of the knife over the sharpening steel will help you to maintain the sharpness of a good blade.
