If you study an art that has sword, or hojojutsu, then it is very natural to learn those skills. But if you study aikido, as the original poster does, and then teach yourself bagua weapons (as he seems to do) then that is another matter.
Ok, correction on my part. These are the arts that he lists as studying.
Ba gua zhang, Xing Yi, Taji, Aikido
Ok, so he is not teaching himself bagua weapons. But my point remains the same.
OUMoose, I happen to study the sword. I started learning it because the tradition I studied had is as part of what a student was supposed to learn at a certain level. Since then, I have found that learning the sword has helped my empty hand aspects and my understanding of the art.
But let us say that someone with a Shotokan background wanted to learn the Chinese
jiang without going to a teacher. Wouldn't that be something you would discourage?
The jujutsu styles I have studied with hojojutsu are totally different from the arts he listed. The hold- downs of the jujutsu styles with hojojutsu all seem to end up with the other guy face flat on the ground and his arms behind him. From there the hojojutsu is easy to apply. Without learning these types of holds IMO there is little relevence to hojojutsu and martial arts. Unlike sword, hojojutsu will not help your footwork and understanding of space.
And it can be dangerous. Some of the traditional ties I learned were set up so that if a person tried to struggle he would slowly choke himself unless he stopped. From what I have seen, these have been taken out of the modern "fun" versions of the art as practiced by people with different sexual tastes.
So you see why I do not see a
martial arts reason to learn this type of thing. There is no use for it for most people and it is not part of a tradtion he does and thus will not help the arts he studies. I honestly think it is like someone studying Shotokan picking up a book on using the Jiang and teaching themselves.
