The Compendio blades are made using a mix of Carbon Steel & Stainless Steel then polished to a glossy finish and set with Ice Lucite Handles. 7pc Set includes a black lucite knife block for knife storage. The new blade technology allows for a lighter blade than a forged knife while still offering exceptional performance. The unique convex shape of the blade allows for the edge to remain sharper for a longer period of time. This is Berti's newest blade technology that still delivers high performance for discerning customers while allowing for a unique and modern new look.
