Seiryu Katana
Seiryu Katana
The Seiryu Katana is centred on an Azure Loong composition worked through the fittings. Blue and gold lacquer on the hardwood saya extends that colour story beyond the guard, giving the katana a clear visual identity from blade to scabbard.
The Damascus blade is listed with clay tempering, while copper loong details repeat across the mount. The result is a coordinated blue-and-gold presentation rather than a generic dragon motif placed on an otherwise neutral sword.
