Wusthof Classic Ikon knives feature a distinctive, double bolster design for professional-style heft, exceptional balance and beauty. The handle is made of a highly durable synthetic material Polyoxymethylene (POM) which has a tighter molecular structure to resist fading and discoloration. The elegant shape of the handle is designed for a comfortable grip. The Classic 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.
