The funny thing to me is hammer fist are a really traditional movement that used to be all the rage. Then MMA fighters tarted using it while ROLLING AROUND ON THE GROUND! It's like all the TMA tards gave up on it once someone proved that it works. lol
I don't know how to copy a pdf... But the Oyama pic made me think that the chicken peck punch/strike would probably work (when done by Oyama).
All this reminds me of Motobu (or wtf his name was) who KO'd the boxer with a single knuckle strike. 10,000 makiwara strikes and the **** works!
