Wo Yao Dao (Japanese style waist saber) is a single handed saber. It has a slender profile, with an accelerated curve towards the tip, which is typical for Ming to early Qing sabers. It has a ridged cross-section, much in the style of Japanese swords but without the kissaki that is so characteristic for Japanese work.
Since the Song Dynasty, the quality of Japanese swords was well received and the Ming government set up import trade agreement with Japanese feudal lords of the sword production areas in Japan. Between the 115 years from 1432 to 1547, there were 11 official sword import contracts and many unaccountable smuggling of Japanese swords via Macao. The number of Japanese swords imported were number over 200,000. These Japanese swords were often made to Chinese specifications to adapt to single handed use and the imported swords are of various qualities and not all were heirloom quality.
With the abundance of Japanese imports as inspiration, Chinese sword makers craft swords with Japanese influence and with Chinese forging techniques, the results were often blades with equivalent quality of the imports with the added benefits of local repair and restoration if needed.
This Wo Yao Dao is closely based on an antique Late Ming Dynasty Yao Dao in the fame Mandarin Mansion Collection.

Fit and finish
We perfected the fit and finish of our swords and the assembly is meticulously performed by our senior craft masters. It takes one whole working day for a craftsman to assemble our swords.
Sword Dynamics is first conceived by Peter Johnsson to objectively record the dynamics properties of medieval swords he encountered.
