Why Pekiti Tirsia Kali?

Pekiti Tirsia Kali, refered to as PTK, is a complete system incorporating both weapons and empty hands methods, based on tactics and strategies derived from edged weapons. In PTK, there is only one set of fighting tactics no matter if attacker or defender is armed or unarmed regardless of weapon. This structure allows a more economic use of practice time and creates confidence through understanding and experience. If a method works against an opponent armed with a knife, it also works against the unarmed opponent. This is known as the principle of transferable technology. Designed for both single and multiple attackers, PTK is an ancient art that has evolved to stay relevant for modern combat and self-defense situations.

PTK is proven effective in combat and invaluable for preparing the average citizen regardless of age, capability or experience, to law enforcement and military community members. In the country of origin, PTK has become the basis for the official combatives programs of the Armed Forces of the Philippines and Philippine National Police. Internationally, it has been taught to thousands of police and military Special Operations personnel in the United States, Europe, India, Russia and across Asia. 


 In the PTK system mastery is acquired by the application of movements, controlling the outcome of opponents’ movements, use of distance and attacking, countering, and re-countering tactics. PTK relies on precise footwork and movement patterns as a foundation that emphasizes correct movements with a purpose.


Full understanding of PTK leads to continuous improvement and continued adaptation of its methods to new demands. PTK today is a valuable and practical Survival Art. It continues to be proven effective in combat and indispensable for today’s heroes of the law enforcement, military, and security communities. 

An important part of Pekiti-Tirsia Kali is its positive, life appreciating philosophy and faith in a higher, spiritual power. For more information on the Pekiti Tirsia Kali philosophy and faith, click here.
