What visual configurations are available in the 1090 carbon steel katana collection?
Updated Feb 2026
1090 carbon steel katana in this collection are available across a broader range of visual configurations than most single-steel-grade collections because 1090's surface quality supports an unusually wide variety of finish treatments. Golden blade finish pieces are the most distinctive: the warm metallic-gold tone created by specific heat treatment on 1090 steel creates a blade appearance that is quite different from the conventional silver-metallic finish of standard carbon steel, and distinct from the color blade treatments of Manganese Steel pieces. Black finish configurations range from classic matte-black blade and scabbard presentations to bamboo-themed and dragon-themed scabbard designs. Vivid color blade treatment pieces in blue, red, and purple demonstrate 1090's surface quality for chromatic finishes. Dragon-themed configurations include both black dragon and red dragon scabbard patterns. The full collection spans from conservative traditional presentations through to bold color configurations within a single high-performance carbon steel grade.
