The Tojiro DP Damascus Series combines the quality of the DP 3 - Layer Series with the benefits of Damascus steel. The core of Tojiro DP Damascus knives is pure stain resistant high carbon steel cobalt alloy overlaid with 36 separate fine layers of high and low-carbon stainless steel. The fine layering of Damascus steel makes these knives exceptionally strong and flexible. Tojiro DP Damascus knives have handles made from ECO resin impregnated wood for durability.
