Does the black aesthetic affect the materials used in these tanto?
Updated Mar 2026
Yes — achieving a cohesive all-black presentation typically involves deliberate material and finish choices across multiple components. The saya is generally lacquered or wrapped in a matte or gloss black finish, the sageo cord is dyed to match, and the handle fittings such as the kashira and fuchi are either coated, oxidized, or manufactured in black-anodized alloy. In dragon-engraved stainless steel variants, the blade itself may receive a dark etching treatment that enhances contrast between the engraved design and the surrounding surface. Each of these finishing decisions is made independently and contributes to the final visual unity of the piece — which is part of what makes a well-executed black tsuba aikuchi a genuinely considered collectible rather than simply a painted version of a standard tanto.
