A lot of JKD folks such as Paul Vunak seem to swear by the straight blast. I've seen it used before in a street fight in Hawaii, where MMA is extremely popular. It was a smaller guy (though in excellent shape, and clearly a martial artist by his response), and he did a straight blast to a much bigger guy.

Although many folks are using more of the boxing blast these days, the straight vertical blast is “decent”. A friend of mine used it with success while in Spain in a situation.


Like most real fights, it went to the ground, but the smaller guy clearly knew BJJ as well and he seemed to take it to the ground on purpose... the bigger guy was on top, but the smaller guy immediately had him in full guard with the legs and then he was able to leverage him, turn him around on his back and straighten his body. It looked like he was going to do some sort of submission, but the fight was stopped by other people.

I love it when smaller guys show some skill in fights! Sounds like the guy was pretty well rounded. Its amazing how well a simple strategy works to defend yourself. A simple straight blast and a little grappling knowledge will go a long way against the majority of average Joe’s.


But the blast really stunned the guy and he nearly fell over before it was taken to the ground. He walked away with a bloody face, and the smaller guy had no visible damage. He didn't do a complete centerline blast, but got some face strikes in too.

Good stuff. The smaller guy was totally dominant and the blast was completely effective against a much larger opponent. It allowed him to do what it's intended for: throw him off balance, stun and take control.

That’s the idea. Again, a simple strategy is often more effective. Some people have talked smack about Vunak and PFS in recent years. While I don’t agree with everything that they do, Vunak does preach a simple (and effective) strategy for self defense that has been shown to work quite well.
