Workshop On Palm Stick fighting methods of Kun Tao Dumpag
This unique Filipino martial art workshop will be conducted by Ron Kosakowski
Sunday, June 4th 2006 10:30am to 3:00 pm

Practical Self Defense Training Center
847 Hamilton Avenue (Route 69)
Waterbury, Connecticut

Lunch break for one half hour (it would be best to bring a lunch)

Welcome to the 57th bi-monthly PSDTC workshop! This workshop you will see some of the unique characteristics of the Palm Stick Fighting methods of Kun Tao Dumpag (Philippine palm stick, also known as Olisi Palad or Dulo Dulo). You will learn the techniques as well as the training methods that give you the reflex to pull off these techniques. 
       Ron Kosakowski was the only student of the late Grand Master Joe Rossi that was taught the palm stick! These techniques that will be shown are very dangerous for the receiving side of these weapons. The Palm Stick is deceptively non lethal looking but it can be used for nerve pinching, joint manipulations, nerve destructions to take downs, controlling an opponent or to whatever extreme necessary. You will also learn how this weapon will help tremendously for much needed leverage self defense areas for multi man attacks with or without a weapon. Understanding this unusual weapon will give you a rare look into this fighting style of Kun Tao and how it can be taken to any direction in actual combat situations. If you are looking for a real true ancient warrior style that is well preserved in its native Filipino customs, this workshop is for you!
       For self defense purposes, this is just another direction that will help you understand how to defend your self in a street attack that much better...knowledge is power as long as you know where, when and how to pull off that knowledge! Kun Tao is NOT a tournament sport! Taught correctly, it is a serious survival oriented vicious fighting style! Male or female; regardless of size or strength, you will not want to miss this opportunity to train in a unique self defense weapon from this particular Filipino Martial Art!
