The Wusthof Classic Ikon 7 inch fillet knife has a very thin flexible blade used for deboning and filleting fish. It includes a leather sheath for storage and protection. The long narrow blade of the fillet knife allows you to move smoothly along the backbone of the fish and easily remove the skin. The Wusthof Classic Ikon collection features a handle with an elegant shape and comfortable grip, as well as a double bolster for heft and balance.
