1. Spite is a funny word. sorry. 2.Actually, I was told they were there by one of the few 7'th degree black belts of the system. 3. this is funny. There is a Karate practitioner of three years telling you it has ground fighting and you tell me it doesn't. I guess it's just in my imagination then right?
The style, Shorin Ryu. Were they got it, I'm not one of the founding Okinawans, so I can't say. The techniques, any techniques you decided to interprit as ground based.
If I had some distance I would throw the shurikan at him, if he was close I would smack him with the nunchaku, a hit with a nunchaku over the top of the head would probably split the skin... or at least make a would be attacker cry.
If your already in boxing range, do the tyson manuvour and chomp off his ear. I would probably use an uppercut to come up under his chin and strike his throat. Or grab him and pull him into a knee in the nuts.
