The outstanding properties of Kyocera ceramic knives make cooking a real pleasure! The knives glide very easily through even delicate goods. Zirconium oxide blades stay razor sharp at least 10 times longer than traditional cutlery, making them ideal for everyday use. Unlike steel blades, ceramic blades will never rust or change from its natural state. The 16 cm Chef's Knife is a fantastic all-purpose knife and is actually stronger than the white knife of the same size. A great addition to any home kitchen.
