The Chinese Double Dao or Double Broadsword is used as a slashing weapons but now with twice as many variables for the Warrior Monk. The back of the blade is used for blocking while the sharpened edge is what does the damage to the opponent. This weapon may seem to be fancy but when facing it your totally confused as to which blade is coming at you. The single Dao is one of the 4 major weapons and the doubloe Dao is just a simple derivation to the single blade.
