Thank you for your response!!! Is is true that i am one of the grandsons (you can check my birth certificate), and i am not well-trained in fma. I have learned bits and pieces of a military style knife techniques with my grandfather taught as part of "sentry removal". As to fma, i had the chane of doing a couple sessions with Edgar Sulite in my younger days (by accident when he came to our dojo to practice) and GM Presas was my PE instructor. My background started with shotokan (which my grandmother hated because it's japanese), which i had to switched to taekwondo and hapkido (currently teaching both).
Anyway, i have kept tracked with a lot of the blogs about fma and am very impressed with what everybody has accomplished. FMA has evolved so much and became a very dangerous system. In fact, i have spoken/communicated with a couple GMs, a few years back, wanting me to join in their systems. I have no intention of doing so since i can not represent my grandfather's legacy just because i have his name/bloodline. I was raised by my grandfather and he did not consider what he taught me as martial arts.
The reason i posted this thread was that i saw an ad about someone promoting/teaching "the saavedra system" and there were a few people biting and wanting to be trained. Like you mentioned, "any others were not as well trained, if trained at all". It just bugs me that there are people using the name for their own purpose. There's no need to drag people that couldn't say something it. My grandfather even refused to talk about his experiences and people he killed (i do have proof - his military medals, marksmanship and all). Anyway, once again, thank you!!
