My fighting situation takes a little while to explain. My brother (Tae Kwon Do expert) and my dad (all-around badass, apparently) taught me a few maneuvers, but nothing really acrobatic and stylish. However, at a young age, I took a liking to sword-fighting, as my brother bought a couple of bamboo swords and taught me a few basics (basic blocks) for little giggles. From there, I went on to develop my own style over the years, one that complimented my strengths and range of motion. It turned out to be so effective that after a while, I surpassed my brother.
In more recent years, I took basic patterns from my sword style and tried to translate it to a hand-to-hand format. This has resulted in a style that seems to be a sort of semi-disciplined mixture of Muay Thai and Karate. Unfortunately, I don't know if these techniques actually work, being that I haven't had the opportunity to use them in a real fight.
So can I defend myself? Possibly. However, though it might be arrogance that fuels this answer, I think the answer is more likely "yes" than "no," considering the state of mind that comes over me when I am thoroughly convinced I'm going to have to fight.
