My first post here.... I've been watching Shihan Abernethy's videos for a long time now and have found them incredibly enlightening. I've also enjoyed reading many of the discussions, and I hope to contribute a few ideas sometime if I can ever sit down and write them up.
I found a video of his some time ago that talked about what we would call in our style the augmented knifehand or shuto block. Here's an example, at the beginning of our Taikyoku Shi:
It's also the concluding techniques in Heian Shodan/Pinan Nidan (our Pinan Ichi), if that helps.
The video in question explained that when the shuto of what we would call the augmenting hand comes to the solar plexus, it's about control of the attacker's elbow, and when it comes to the side (we would place it under the floating rib) it's about control of the attacker's wrist.
Here's my delimma: I can't remember which video that is, and there's so many clips out there! I've literally spent hours running through the YouTube channel but can't find it, though I've found many great examples where he explains how that motion can turn into or set up arm bars, throws, and so forth.
I'm wondering if anyone can remember which video I'm writing about…. I'd like to share it with one of my students. I think it would help him understand parts of one of our kata much better than I can!
Meanwhile, thank you all so much for the productive, positive martial arts discussions!
