A necessity for the serious chef, the Elite Chef Black Ceramic Knife 6-Piece Set includes 3 ultra-sharp 100% ceramic knives with 3 matching sheathes. Each knife is designed to slice through fruits, vegetables, and boneless meats with unmatched ease. Featuring 3 convenient sizes (3”, 5” and 6” blades) coupled to perfectly balanced ergonomic handles, the Elite Chef Ceramic Knives render a wide variety of cutting tasks effortless, from chopping, to mincing, slicing and dicing. These distinctively shaped knives utilize Australian source zircon sand for the finest ceramic quality, with each blade close in hardness to diamonds and able to preserve its razor-sharpness 10 times longer than traditional steel blades. The Ozeri Elite Chef ceramic knives are distinguished by convex edges and 36 degree cutting angles, which offer enhanced sharpness over traditional 45 degree ceramic blades. Unlike metal knives, the Ozeri Elite Chef Black Ceramic Knives do not corrode, rust or leach metal ions into food. They are impervious to moisture, oils and acids in common foods, and preserve their freshness despite long-term exposure to such foods. Finished with a reflective black veneer, each Ozeri ceramic knife weighs less than half of an equivalent metal knife, thereby reducing fatigue and pain associating with preparing big meals and repetitive cutting.
