    by Bill McGrath
    A few techniques from the Sagang Labo drill of Pekiti-Tirsia. There is much more to this drill than what you commonly see at seminars. Sagang-Labo translates to “Block” and “Hack or Slash” in the Hiligaynon version of Visayan from the island of Negros.

  • MODERN TRAINING TIME: HOW FAST VS HOW MUCH

    by Bill McGrath
    Grand Tuhon Gaje would often tell the story of how he began Pekiti-Tirsia training at the age of six, under his maternal grandfather Conrado Tortal. Conrado began young Leo’s training with three long years of footwork. Conrado started Leo on a rickety old table in the home, moving in forward and reverse triangles, while his grandfather tapped his leg with a stick at the apex of the movement to get him to move faster. After a few weeks of this Conrado moved his grandson to training on the halves of three coconut shells, while stepping with only one foot at a time on each shell.

  • CAN WE TALK ABOUT THAT GRIP

    by Bill McGrath
    Back in the 1970s, when I first started learning Pekiti-Tirsia knife work, Tuhon Gaje had us do many exercises to strengthen our grip. Things like doing push ups while holding our rattan sticks with the butt end braced on the floor, as well as striking and thrusting our sticks full power into a stack of car tires.
