What material is used for gold black tsuba on these katana?
Updated Mar 2026
The tsuba on these collectible katana are cast from gold-toned zinc alloy or brass-based alloy, then finished with blackened relief detailing to produce the high-contrast gold-and-black appearance. This is a standard approach in decorative koshirae production - the same material class used in many museum-replica fittings. The alloy holds fine engraved detail well, resists minor handling, and maintains its finish under typical indoor display conditions. It is not solid gold, nor is it intended to be: the goal is accurate visual reproduction of the ornate guard styles found on formal Japanese swords from the Edo period, where gilded metalwork was a common marker of status and craftsmanship.
