Qi-Ja Yao Dao (General Qi's waist saber) is a single handed military saber. The blade has a gentle curve, a single fuller and a flat back ridge. Most saber fittings of this era were made of iron with solid and austere aesthetics.
This Yao Dao is is closely modeled after an antique Ming Dynasty Yao Dao in LK Chen's private collection.
In General Qi JiGuang's (1528-1588) treatise "Practical Guide for Military Training" he stated: "To forge a good Yao Dao, iron needs to be folded many times to improve it's quality, the edge needs to be of hard steel. The blade needs to be polish with smooth profile, the tip needs to be sharp ...."

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.
