Liuyedao
The liuyedao or willow-leaf saber is a type of dao that was commonly used as a military sidearm for both cavalry and infantry during the Ming and Qing dynasties. A descedent of the earlier Mongol saber the liuyedao remained the most popular type of single handed sabre during the Ming Dynasty, replacing the role of the military role of the Jian. Many schools of Chinese martial arts originally trained with this weapon.
This weapon features a moderate curve along the length of the blade. This reduces thrusting ability while increasing the power of cuts and slashes. The hilts are typically straight, but can be re-curved downward starting in the 18th century. It weighs from two to three pounds, and is 36 to 39 inches long.
Many examples will often have a decorated collar at the throat of the blade called a tunkou, which are stylistic holdovers from the preceding Mongol designs.
