This blade features a Coloured Damascus finish (有色ダマスカス), in which the layered steel pattern is enhanced not only through etching, but also through controlled oxidation or heat-patina techniques to produce a vibrant and unique hue across the surface. Depending on the artisan’s intent and the finishing process, the blade may show tones of bronze, orange, purple, or even iridescent colour shifts.

Unlike standard etched Damascus, which yields a black or grey contrast, Coloured Damascus takes the visual complexity further—adding warmth and depth to the pattern through carefully managed surface reactions. These finishes are often found on high-end or art-grade blades, where the Damascus is treated as both a structural and aesthetic canvas.

The result is a blade that not only performs beautifully but also stands out as a functional piece of metalwork art, each with a one-of-a-kind appearance.
