The best reason and time to celebrate Arnis Day in Negros Island is perhaps Novermber 5 of each year. As Al Cinco de Noviembre exemplifies the most daring strategy of our heroes who "with a thousand bolo-men took positions at the Lupit River in the south-east of Bacolod. The wily revolutionaries augmented their lightly-armed men with "cannon" made of bamboo and rolled amakan, and "rifles" carved out of wood and coconut fronds" caused the surrender of the Spanish forces on November 6, 1898 (Source: http://en.wikipedia.org/wiki/Negros_Revolution). The bluff, use of the bolos, and wood were proof of the martial skills and strategic thinking of the Negrosanon at the time of the revolution.
The Bolo
A bolo is a large cutting tool similar to the machete, used particularly in the jungles of Indonesia, the Philippines, and in the sugar fields of Cuba. The primary use for the bolo is clearing vegetation, whether for agriculture or during trail blazing.
The bolo is called an itak in Tagalog while in Hiligaynon, the blade is referred to as either a binangon or a talibong.
Historical significance

General Juan Araneta depicted on horseback also wielding a fighting bolo. General Juan Araneta's monument was erected in Bago City, Negros Occidental.
Bolos are also used as military weapons and as such they were a particular favorite of the Filipino resistance during the 1898 Philippine Revolution against Spain, the Philippine-American War, and the Commonwealth period. Since the bolo was first used as a farming implement, it was used in combat because during colonial times the ubiquitous bolo was readily available to the common person (Source: http://en.wikipedia.org/wiki/Bolo_knife)
