Sounds like a movie, but they actually fight each other with swords to prove their point. Much realer than the Filipino arts and Japanese Kendo/Kenjutsu...these guys actually duel with live blades without protective gear. The only reason I can gather that people have not heard of this is martial art is politics and money...they don't want you to know these people are out there. But, they are. What you are training in probably won't prepare you for the this. And if you think it does, try your hand against one of these people. It's not hard to do, just visit the Dominican Republic and start asking about the "Tigueres" and Machete Fights. I am sure they will be more than willing to accommodate you.
