Damascus (Suminagashi)
suminagashi
A flowing, wood-grain pattern on a blade's outer steel, created by forging many layers together. It is decorative and does not change how the knife cuts.
On a modern Japanese knife, “Damascus” (in Japanese, suminagashi, 墨流し, “flowing ink”) refers to a visible layered pattern on the outer steel of a clad blade, made by folding and forging dozens or hundreds of layers before etching them to bring out the contrast. It is purely cosmetic. The pattern is in the soft cladding, not the cutting core, so it has no effect on sharpness or edge retention. A Damascus knife cuts exactly as well as the same knife with a plain finish, and you are paying for the look and the extra forging work.
