The dao is a Chinese saber, sometimes translated as a "broadsword. The weapon's design varies somewhat through time, but in general, it is a short, wide-bladed sword with a moderate curve, designed for slashing and chopping, though it has a secondary thrusting capability. The dao is said to be one of the easiest swords to learn to use in combat, taking only a few days of training.

The dao have existed for centuries of Chinese history, although single-handed versions evolved during the Ming Dynasty. During World War II, shortages of firearms forced some Chinese soldiers to fight with dao. This wasn't so unusual as Japanese Imperialist troops also used Katanas during the war. It is still practiced in modern wushu, where it is known as the "General of All Weapons". The dao can also be used as a thrusting weapon as well as a hacking weapon.
