PALATIAL TANG DAO (618-907 AD)

Palatial Tang Dao is another celebration of the diversity of Tang Heng Dao featuring a straight and chisel blade profile. 

Like the military Tang Heng Dao, this is a single handed straight dao featuring a scabbard with two-point suspension system influenced by the Sasanian swords.  Palatial Tang Dao can be used for combat on foot as well as on horseback. Palatial Tang Dao was powerful and was the standard side arm for imperial guards.  

Tang Dao was expensive to make and each piece worth about one month's salary of a junior level government official.  As an expensive military resource, Tang Dao was forbidden to be used as funeral goods.  As a result, there were very few unearthed specimens found today. Fortunately, Tang Dao was pursued by the Japanese delegates and sent back to Japan as treasures for the royal court and those few rare Tang Dao samples are preserved in Nara today. 

The fitting design of Palatial Tang Dao is based on a rare Tang Dao in private collection.
