Whats the largest sword (used for war) or two handed sword the anamist filipinos used of visayan and luzon?

Pardon me, but you got a wrong source, try reading History of Panay Island written by Atty. Rex Sodevilla. Even before Lapulapu the brave, moro warrior killed Purtuguese navigator Ferdinand Magellan, the ten Bornean Datus , who escaped from their cruel King, landed in various parts of Philippine Islands one of those was Datu Paiborong, who landed in Panay Island, specifically in a place named after him later, " Irong-Irong", now known as Iloilo, in a southern part called Tiolas, Sn Joaquin. He established a school for warriors called " Botho-an", where Kali and ancient Sword Fighting Techniques are taught. Modesty aside Visayans, especially Ilonggos are well respected Tribe among settlers in both Muslim and Christian areas in Mindanao. Your source is inaccurate, try doing some research, it's not good to speculate and insult our rich culture calling us "naked bunch of uncivilized freaks". Probably what you were referring to were the Aetas, a mountain people found in some parts of the country, they are not Visayan, and much more not Ilonggos.
