This is a kampilan sword, carried by the Moros of Sulu and Mindanao, Philippines. The kampilan is considered to be their "national weapon", although many different types of swords can be found in the region. The kampilan is frequently cited in documents from the Spanish Conquistadors during the colonization of Spain from 1565 to 1898.
The kampilan is the longest sword carried by Moro warriors. The overall length of this example is 36 ¼ inches. The blade is ¼ inch thick at the bolster, tapering distally along the spine to a double edge at the flare.
