someone please correct me if I'm wrong:
I get the impression, from what I've read and from friends who have been there, that the Aikikai Hombu Dojo does not have a specific curriculum for weapons training.
If that's correct, then how did the current generation of instructors in the Aikikai develop their technique? I've had the opportunity to attend seminars taught by Endo sensei, Osawa sensei, Yokota sensei and alike and weapons training is hardly mentioned. From what I've seen or felt, I wouldn't even begin to think that that their technique is the least bit hampered by a lack of weapons tranining.
