I'm just now getting around to watching this video. To me, it does look an awful lot like Tae Kwon Do and some Jiu-Jitsu thrown in. One thing that disturbed me about this video, was when Nage either didn't think to, or allowed Uke to retain the knife. You will note in a few instances where Uke still has possession of the weapon even when the technique has been executed. Nage doesn't really try and disarm Uke and/or retreat. Just my 2 cents.
