The combative traditions of the Philippines are many and varied. Although these traditions share a focus on the stick and the blade, there are often subtle differences between them, that reflect diverse regional histories, and the unique experience of their founders. Bernas Estocadas is a system of Filipino Martial Arts (FMA) developed by Grandmaster William Bernas, with roots in the informal but practical Wido (alt. Oido) Baston (stick), Olisi (longstick), Sungkod (staff), Talibong (single-edged sword) and Gunting (scissor-sword) fighting traditions of Negros Occidental he learned from his Grandfather and Uncle while growing up in Escalante, and inspiration from the systematic and structured Pekiti Tirsia (or "close quarters") Espada y Daga (sword & dagger) methods he encountered in the Navales Arnis Clinic in Bacolod. It includes training in methods of stick, blade, and empty hand self protection against an armed or unarmed opponent.
