The Vietnamese Xa Mau (or ''Snake Pole''), was a Medieval Southeast Asia Pole Arm, common with some Military Units in the 16th to 18th Century. Used as both an Infantry and Cavalry (Mounted) weapon, The Xa Mau was noted for it;s unusual curved metal blade – which resembled a ''slithering'' serpent. Typically mounted on a 6-foot wooden Pole, the actual blade was 2.5-feet in general length. Both sides of the ''waved'' blade was sharpened, with a slight point at the tip. The ''end'' of The Snake was a curved hook which was used to pull down an Enemy Rider – or m could be used by Mounted Troops to ''hook onto'' armor and thus ''unhorse'' them.
