  • PEKITI-TIRSIA ESPADA Y DAGA WEAPONS EXPERIMENT (Set 1 Tools)

    by Tuhon Bill McGrath

    In December of 2025, Jared Wihongi and I had a proposal for all Pekiti-Tirsia instructors from all organizations; to try an experiment using swords and knives for each of the 3 sets of our Espada y Daga, using different size tools for each set.

    This essay is designed to give Pekiti instructors some samples of how to design drills around these tools, beginning with the blades for set one (sets 2 and 3 to follow in the coming weeks). 

    The purpose of this experiment is as an exercise to develop problem solving skills, using these specific weapons and samples; but your goal is to be able to apply these principles in a variety of situations.

  • How to measure Sticks, Swords, Knives and Spears in the Pekiti-Tirsia System.

    by Tuhon Bill McGrath
    I have been asked many times to give the measurements of the Pekiti-Tirsia long sword shown in the PTI logo. The information on the measurements was told to me many years ago by Tuhon Gaje. In this essay I will give the measurements for two swords, the long sword shown in the PTI logo and the short sword that Tuhon Gaje is often shown holding in the photos of him from the early 1980's. I am also including the measurements for training sticks and spears, as well as knives intended for use with Sak-Sak and Pakal grips.
