Eskrima, Arnis, and Kali are umbrella terms for the traditional martial arts of the Philippines (Filipino Martial Arts, FMA) that emphasize weapon-based fighting with sticks, knives and other bladed weapons, and various improvised weapons. It also includes hand-to-hand combat, joint locks, grappling, and weapon disarming techniques. Although, in general, emphasis is put on weapons for these arts, some systems put empty hands as the primary focus and some old school systems do not teach weapons at all.
