The Zhen Premium Damascus series knives are made of Damascus VG-10 steel (HRC 60-62) steel imported from Japan and have durable ebony-colored Pakkawood handles. The blades are now made by welding 67 layers of steel together creating a high quality blade with a keen edge and very unique, beautiful dragon pattern. These layers wear at a slightly different rate, causing a very fine micro-serration which produces an edge which is extremely sharp and holds its edge for a longer period of time. The knives are designed with the professional cook in mind, nicely balanced and comfortable in the hand.
