The meijin Katana represents the pinnacle of production quality for Shinken. The blade is forged-folded T10 high-carbon steel with Bo-hi, making for a lighter blade and audible feedback on the cutting stroke. The blade is differentially hardened using a traditional claying method and has a distinctive grain pattern (Hada) with visible layers. The Meijin has a very sharp edge and is capable of light target cutting. The tsuka is wrapped in genuine ray skin (Same) with a Tsuka-ito in premium black Japanese cotton. The black iron koshirae display a "Turbulent Ocean" motif. The saya is finished in a distinctive black matte/gloss banded finish extending the length of the scabbard, with a black Japanese cotton sageo.
