The Miyabi Black 5000MCD is a true work of art. The blade is constructed of micro-carbide powdered MC66 steel, which is ice-hardened to an impressive 66 HRC. This results in an exceptionally sharp and lasting edge. The blade is wrapped in 132 additional layers of steel, resulting in a beautiful flower damascus pattern. The handle of the Miyabi Black series is made from the prized Bigleaf maple and dyed a black ash color. The grain and color of the black ash contrasts beautifully with the Damascus pattern of the blade. The handle is crafted in a traditional "D" shape, with a rounded spine and heel, providing optimal ergonomics for fatigue-free cutting. Handcrafted in Seki, Japan.
