The Dao, or broadsword in common translations, is one of the four major weapons in Chinese martial arts. The dao is primarily a slashing and chopping sword with a single edge. Chines folklore refers to the dao as “The General of all Weapons.”
The School of Shaolin Kung Fu teaches multiple broadsword forms.
