You've set up a situation that allows me to articulate thoughts I've been wanting to express for some time. You wrote...
Allow me, if I may, to play devil's advocate to these comments. And this is not for sport; I am passionate about the veracity of my beliefs.Even if, as you and Tomoyose sensei said, we wasted a lifetime training our spear hand etc., there is still lots of doubt in my mind, according to research by Siddle, that we would be able to use such weapons under stress, and to hit the so called “pressure points”.
While punches to the face should be discouraged by a good sensei, because of the likely possibility of ending up with a broken hand or blood poisoning, when it comes to the rib cage, a good chest caving punch is king, because it is all gross motor and will work wonders, along with knees and elbows, especially the type used by Muay Thai fighters, that are much more superior to what we think we have in Uechi.
First... One does not "waste time" training one's fingers and toes. On the contrary, I think folks waste time practicing a style like Uechi Ryu and then never taking the time to follow through and work the hands and feet like Uechi Kanbun, his peers, his students (like Tomoyose senior and junior) and teachers did. Frankly I want to tell the good lot of folks to leave Uechi and practice Goju; what they do is no different. They get no advantage from the Uechi view of sanchin.
Second... I see nothing in Muay Thai that isn't already in Uechi Ryu. No Muay Thai boxer did anything in a match that I didn't already see in my Uechi Ryu; we have all that and then some. It's only an issue of emphasis.
Third... Bruce Siddle is also the guy that spent several days in a Thompson Island Uechi camp teaching PPCT. You know... that pressure point stuff that Jimmy Malone also teaches thanks to Bruce. And what does Bruce like to use? A tip of thumb strike. If you look at what he uses and teaches, you will realize it's Uechi - for all practical purposes.
So what's the discrepancy here? It's several issues. First, there is the force continuum. Not every self defense situation requires that we cave someone's chest in with a punch. For example, verbal defense skills are an important part of training for anyone from a soldier to a law officer to a common citizen. Even U.S. Marines train techniques that require small motor coordination. Second, Siddle spent a good deal of his writing discussing the idea of operating in an ideal physiologic "zone" where all the bad things associated with the "dump" (to use the vernacular) don't happen. LOT'S written about this... Good stuff. Darren Laur's page summarizes a good deal of it.
I do it all. I train it all. And yes, I have used things like shokens and boshikens in low-level self defense situations.
Finally... These weapons aren't just about thrusting or striking. They are also about grabbing. There is absolutely no match I know of on this martial earth for a Uechika with well-trained hands. Add in some grappling skills and you've got yourself a complete warrior.
Rant off...
