The strength and density of ceramic allows the blades on these knives to be ground to microscopic precision with diamond wheels. The result is a razor-sharp blade that retains its original, unrelenting sharpness for more than 10 times longer than steel knives. Plus, ceramic is lightweight and impervious to acids, juices, oils, salts and other elements that might alter the taste or appearance of your food. Handle is constructed of Pakka wood and features a Damascus-look. Hand wash. Limited five-year warranty.
