The 10-inch honing steel will keep your ikon knives in top condition. A few swipes of the knife is all it takes to maintain your fine cutting edge. The Wusthof Ikon is culmination of all the best features of each of the Wusthof knife lines. The combined riveted handle design is combined with a contoured shape to add comfort and control. The handles are made of African Grenadill wood. African Grenadill wood is the worlds densest wood and expands and contract less than most traditional woods. These handles are hand crafted and fitted to each knife. The Ikon adds a rear bolster that acts as a counter balance when using the knife. This second bolster adds counter balance. Wusthof uses a special blend of German steel through out the whole length of the steel. The ingredients of this steel are proudly etched on each blade. Wusthof not only uses the best materials to make a fine knife, but it is also crucial that each blade is precisely tempered. This tempering allows the knife to hold its edge for an extremely long time, yet still be able to be maintained in your home kitchen with out the need to be sent away for maintenance. Located in "The Cutlery Capital of the World", Solingen Germany, the Wusthof factory history goes back as far as 1814 when the company was listed with the Duchy of Berg. To this day, the company remains family owned.
