What are the different finishes available for ninjato blades?
Updated Feb 2026
Ninjato blades in this collection are available in a range of surface finishes that suit different display preferences and collection aesthetics. The most traditional option is a polished natural steel finish, which shows the grain structure of the blade steel and highlights the hamon temper line on pieces made from T10 or similar grades. Black-coated blades are among the most popular options for modern display collections - the all-black finish creates a bold, unified look when combined with a black-lacquered scabbard and dark fittings. Some pieces in the collection feature color-treated blades in tones including blue, red, and purple, achieved through heat oxidation or coating treatments that give each sword a distinctive visual character. Mixed-finish pieces combine contrasting elements - for example, a natural steel blade with a black scabbard and red handle wrap - to create layered color interest. Regardless of finish, all blades share the same full-tang construction and high-carbon steel core.
