Evan Sensei-Like your new 'point Du Jour':-) Format.Yes, the toe into speen eleven is certainly no joke.Or Boshiken, or what have you.One wonders what damage could be done with the dread steel toe engineer's special:-)(you listening, Shelly-San?), especially to the underlying femoral artery.
A Martial arts student of my acquaintance who is a surgeon said there is an area also there called Hunter's Cavern of some such and said a sharp strike there could have very dre and far-reaching effects.
There are also a great number of veins, nerves and so on clustered thereabouts.
Once at a seminar I was giving, I beieve entitled 'Cool Stuff 'But the Martial Arts', a participant asked me about the dreaded guard position of Brazilian Jujitsu.Also used in Judo, of course.
So I told him to get me in it, and when he was 'locked on,' I pinched both spleeen eleven points simultaneously.
He went,"Yah!" and let loose fast, rolling out of the way.Good points.Easy to reach, no muss, no fuss, and hours of enjoyment can be had by the entire family.:-)
