Great videos, very informative and easy to follow.
This is very similar to the early Iaido katas I was taught, where you would lead with the Djem So as your draw cut, and then finish with the overhead strike. Main difference is they were done kneeling, but you see similar ideas with the footwork and the way the blade is pointed. My big questions are these:
1. Why drop the blade all the way back on the Sai strikes?
2. Why the flick on the Djem So? It seems a poor economy of movement.
Thanks in advance, hoping to learn.
I have a background in iai, so I think I can kind of help you...sorry guys for delving into alien lingo.
I'm assuming you're referring to the seitei iai set by which you are referring to the seiza kata like
mae and
ushiro. On the surface the
sai cha in Shii-cho (beheading, or cleaving zone 1 from zone 4), which is what I'm guessing you're referring to as Djem So, looks like the
nukutsuke in
mae, but the mechanics are a bit different even if they grossly look the same. The target for the
nukutsuke is to cut across the opponent's eyes and uses the body in a different way than in
sai cha. Instead, think of the
yokogiri (horizontal cut) that's the 2nd to last cut in #11,
sougiri, except it's aimed at the neck instead of across the belly (which would be a
sai tok in Shii-cho). How you use your fingers/hands in conjunction with your arms/hips is *slightly* different based on the fact that the cutting arc is wider with the yokogiri.
So tl;dr -
Sai cha looks similar to a draw cut in that the general trajectory is the same, but I think there are subtle differences in how you employ your body.
As for the other questions:
1. I also struggled with this initially because it's such a major no-no in kenjutsu and iai, but I've seen this kind of cut before in longsword, where it's known as a
Zornhau. Basically, you're making a fully dedicated swing with your entire body behind it and letting the blade follow through the entire trajectory - naturally you end up in the tail guard position.
2. Sorry can't help you with this one, I was kind of curious about this, too, but I understand the principle being demonstrated (not the flick, the cut).
