Forging knife-blades is one of the few old artisanal traditions that have survived to this day. Manual fine labour creates a knife of the greatest precision and sharpness. The Fissler bionic is such a completely hand-made knife for versatile use in the kitchen. It has a harmonious curved form and feels well balanced in the hand of its user. The blade has been made with particular attention to detail. Surprisingly, it has been modelled on the structure of a beaver tooth, which consists of two layers that are worn down at different rates. As a result, the tooth profile always retains an edge that functions like the edge of a sharp stone. The design of the Fissler bionic copies this effect by applying an ultra-hard, high-tech coating to the front of the blade. That produces a knife, which continually sharpens itself. This durable property, which is of such great benefit in everyday use, is enhanced by a special e-protect polish that protects the Fissler bionic from corrosion. A harmonious combination of tradition and high-tech design has created a knife with outstanding properties that will remain an effective and reliable tool for a long time.
