Jassn 4"+5A+7"+peeler+knife Block 5pcs Ceramic Knife Set UNRELENTING SHARPNESS - JASSN ceramic knives are made through a process that produces a very hard material whose hardness is second only to diamonds. After the blade has been sharpened, it can keep its razor sharp edge without wearing out. ODORS - The ceramic materials used in JASSN knives are non-porous which prevent odor and flavor transfer between different foods. SANITARY - Due to the high density and non-porous nature of JASSN ceramic blades, a quick rinse in warm water will thoroughly clean our knives in comparison to steel knives which need detergents and scrubbing. UNPARALLELED PURITY - JASSN Ceramic knives are a pure and healthy alternative to steel blades which can rust and change from their original state. JASSN ceramic knives are totally impervious to acids, juices, oils, salts and other harsh elements. ULTRA LIGHTWEIGHT - JASSN ceramic knives are approximately half the weight of an equivalent steak knife. This creates an extremely comfortable, balanced, and lightweight tool that can be used for long periods of time without causing fatigue.
