There are an enormous variety of bladed weapons in the Philippines. In my article titled Evidence of pre-colonial Filipino Martial Arts, I mentioned that the immense assortment of knives and swords in the archipelago is a solid indicator that there once existed a pre-colonial Filipino martial art. For in design, function precedes form—the early Filipinos would not have made those so many bladed weapons unless they knew how to use them.
