  • 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.

  • HOW TO FIND YOUR PERSONAL FIGHTING STYLE

    by Bill McGrath
    Mohammad Ali and Mike Tyson were both American professional boxers, fighting within a few years of each other and learning the same punches legal in the sport of boxing. Yet these men had very different fighting styles. Why is that?

  • PEKITI-TIRSIA INTERNATIONAL MISSION STATEMENT

    by Bill McGrath
    There are No Secret Techniques in PTI: If all techniques are listed in the course outline it keeps the instructors honest. An instructor cannot say to a student “Do this for me (pay for private lessons/bring a large group to my seminar/etc) and I will teach you these secret techniques.”

  • HOW TO AVOID BECOMING A “KNIFE CULT”

    by Bill McGrath
    Knife work is inherently "dark" and it is all too easy for your students to go over to "The Dark Side" while training in it. While I want my students to take their training seriously (and the consequences of their actions VERY seriously), I don't want them to take themselves or even me too seriously. Here is the danger I am trying to avoid. What should be a defensive tactics class that simply focuses on one practical defensive tool, can easily be turned into "The Cult of the Knife.”

  • KARAMBITS & MAGIC SWORDS

    by Bill McGrath

    “Smell the blade.” said my Indonesian Penchak Silat instructor, Suryadi “Crazy Eddie” Jafri.

    “Why?” I replied, not understanding what this had to do with the question I had asked him.

    “Billy, just smell the blade.”

    Eddie had given me a small Indonesian knife, with a pistol grip and a 3 inch, leaf shaped blade of black damascus steel. It had a strange, elongated hole that looked to be deliberately forged into the center of the blade. The whole thing was small enough to fit into the palm of my hand.
