Iron Fire Martial Arts: Iron is forged in fire and the steel is shaped through many iterations to become what it's designed to be. Iron Fire Martial Arts students are taken on a journey considered the "old way" of training Kuntao and Silat in Indonesia. This way is not easy and there is no substitute for practice, effort and some pain. The rewards on this path are many that can only be explained through growth and achievement. 

Kuntao Silat de Thouars: Kuntao is a term used to describe Chinese influenced martial arts that have made their way to different areas of Southeast Asia. Our various styles of Kuntao are mostly Southern Style Chinese arts taught to my teacher in Indonesia. Kuntao in general is a brutal art with an emphasis of directly attacking the centerline and specific targets on the opponent quickly. You will see extremely low but rooted stances and witness a Kuntao practitioner crashing through opponents bone to bone and leveraging pinpoint accurate strikes leveraging the use of the different animal systems.


Silat, or Pencak Silat comes in many different forms and originated in the Indonesian/Malaysian archipelago. Pencak Silat is a very unorthodox and close range martial art that combines the use of body manipulations, locks, breaks, and sweeps or takedowns with the use of many different bladed weapons. Kuntao and Silat are truly the perfect marriage and together they are extremely effective for self defense situations.


Kuntao Silat has been called the most dangerous martial art in the world by many after they have experienced it.

Benefits of training Martial Arts: Personally, Kuntao Silat martial arts have given me increased physical and mental strength and improved overall abilities. I continue to have great body flexibility, increased range of motion and reduced injuries. Martial arts will teach you situational awareness and self defense strategies. Without sounding full of myself, I do feel confident in my ability to defend myself and my family. ~Guru Colby

Tribute to Grandmaster Willem deThouars

Willem de Thouars is a Dutch-Indonesian born in 1936. He is a humble man with a contagious smile. He is welcoming, caring and full of great stories of experiences throughout his life. Underneath his amazing personality is one of the most skilled martial arts masters I have ever encountered. For those that have had the privilege to learn or "cross hands" in training with him, they will tell you that he is the ultimate master of his craft. He trains martial arts daily and has coined the phrase "Shut up and Train" to remind people that talk is cheap.

The people closest to Willem are asked to refer to him as "Uncle Bill". This is a testament to his humble nature. He often mentions that he is fulfilling his duty to his teachers and passing on their teachings and legacy of Chinese Kuntao, Indonesian Pencak Silat/Serak, fencing, boxing, Corsican blade work and other arts. He looks down at his hands in our class and says "I wear the lessons of my teachers in the palms of my hands and now I am passing these on to you."


I have the great privilege to be training directly with Master Willem de Thouars in Thornton, Colorado, USA. I am honored to pass on what he has taught to me and I swear to wear his teachings and lessons in the palms of my hands.
