Ok I read the article
I dunno which school he trained in
I do take issue that it only advanced Aikido that the hands cut like a sword that ain't true imo
most masters in TJMA are quiet and not loud and brash so that is no surprise, actually any masters should be that way.
I'm not following what he means by the sword strike to the head face that no one can see coming.
Learning to cut is kinda a prerequisite of any sword art and learning the cut to the head well you will in Aikido know that as men uchi or the side cut to the head as shomen uchi so that is no surprise or major difficulty and it is a basic ok it can take a life time to perfect to cut but that could be as he is alluding to zen there but like in Aikido you could spend a lifetime only trying to perfect ikkyo so really no difference
I still don't get the Kenjutsu deflecting hand techs you referred to but there again i we knew the school then we could all go have a look at it's curriculum and see
He has not really said anything in that article that is not other than common knowledge really and the bit about being refused to be taught well some JTMA schools do require a letter of introduction but as he does not state the school and there are no clues unless you know.
The draw and cut he refers to is kinda basic to any school of iai or batto do/jutsu (an I am not gonna start an argument over the different meaning between iai and batto do/jutsu's I am not well enough verse to do that I think I know but I probably don't lol) again depending on the school if they taught that some do some don't, technically it is a different discipline. Kenjutsu can be an umberella term use for all Japanese sword arts (again it not tech correct imo but it is used) so until you know what school he studied it not easy to say.
I still really don't get the kenjutsu sword deflects at all
The Bokken is used in Aikido as a way and method of teaching the thinking that the hands move in a fashion like holding a sword and cutting and the footwork too have a peak at Nishio style of Aikido and I think he was a deshi of Ueshiba but it may have been the second doshu as Ueshiba was in Iwama again by then an I don't know if Nishio was or was just purely at the Aikikai Hombu. I do know he studied many arts to fairly high ranks and he di create his own form off iaido, as I said take a peak as that style of Aikido uses the bokken a lot
