Clarence Mackay Double Dragons Sui Dao was inspired by a rare Sui Dynasty (581 - 618) Dao in the Arms and Armor collection, Metropolitan Museum of Art in New York.
Discovered in 1930 in a royal burial ground outside the Sui Dynasty eastern capital city of Luoyang. Clarence Mackay Double Dragons Sui Dao is a rare example of Sui Dynasty weapon and considered by many a National Treasure. This Sui Dao was brought to New York by Japanese antique dealer Yamanaka Sadajirō and purchased by Irish American Telecommunication Pioneer Clarence H. Mackay (1874-1938) as a gift to the Metropolitan Museum of Art in New York City. It has been in the Arms and Armor collection for the last 90 years.
Clarence Mackay Double Dragons Sui Dao preserved the classic tradition of the Han Dao with a Ring Pommel. The exquisite ring pommel feature a "Double Dragons Chasing a flaming Pearl" motif, that was reserved for the Royal court and officials of senior standing. The blade is straight, sturdy and designed for piercing heavy armor popular at the time rather than cutting soft targets.
The double hung scabbard fitting is based on the design of Iranian Sabers, showing the foreign design influence coming through the Silk Road. The double hang rings enable to Dao to hang horizontally from the body, making this Dao suited for horse riding, demonstrating the ascendance of heavy calvary at the time.
The original Double Dragon have a 14.5 cm handle, our recreation slightly increase the handle length by 1.5 cm (0.59"), with the Ring pin 11 cm (4.3") from hand guard. This subtle adjustment provides a more comfortable grip while preserving the handling characteristics of the original sword.

Fit and finish
We perfected the fit and finish of our swords and the assembly is meticulously performed by our senior craft masters. Sui Dao has 18 pieces of fittings and the assembly is complex. It takes two working days for a craftsman to assemble this Dao.
Leather waist belt with one short and one long vertical suspension straps that tie to the P shape fittings on the scabbard.
This 2 point suspension system allow the sword to hung at 45 degree or more and was first adopted in China during the Northern Dynasties. Since then it was used throughout the Sui and Tang Dynasties until today.
In 1930, Clarance H. Mackay, Irish American telecommunication pioneer, presented the rare Double Dragon Sui Dao, worthy of a Chinese national treasure, to the Metropolitan Museum of Art in New York City. The 'Mackay' Sui Dao was on public display in the Arms and Armor collection for almost a century since Mr. Mackay's generous donation.
