Due to the variety of techniques and skills, and the strenuous nature of the exercises, Okichitaw demands and generates a high level of athletic capabilities, strength, speed, agility, commitment to technique, and mind alertness. In this first work, Chief George J. Lepine, responsible for adapting the Art to current times, shows us the traditional method of solo training, availing ourselves of what Nature offers us. Trees, soil, water and many other different things that we can find around us and that can help us to train with our "Mokiman" knife.When the Philippine Arnis spread in the West, to distinguish it from Fencing, it was called "the living hand fencing", because the hand that did not hold the weapon, actively collaborated in the actions of defense and offense. Thus, the difference between the two systems, the East and the West, is that in Olympic fencing, the unarmed hand is kept safe and used at most to balance the impulse in assaults; in Arnis the unarmed hand is alive and active.
