The jewel of the Wusthof collection, Ikonhas beautifully designed handles made of Grenadill wood. Grenadill wood, or African Blackwood, is one of the hardest and heaviest woods in the world. Ikon full-tang knives are precision-forged from a single piece of an exclusive high-carbon stainless steel and feature a distinctive, double bolster. An Ikon 6" Flexible Fillet Knife has a very thin flexible blade used for deboning and filleting fish. The long narrow blade enables the knife to move smoothly along the backbone of the fish and easily removes the fish skin. The flexible design makes it easier to maneuver around smaller bones.
