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 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 armour popular at the time rather than cutting soft targets.

The double hung scabbard fitting is based on the design of Iranian Sabres, 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 cavalry 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.
