No...not new. Was introduced to this technique in first year Goju, and worked it privately with a visiting Feeding Crane sifu last year. But I'm not confident that this clavicular take down would really work for a female without a lot of practice...and I'm rather too fond of my sensei to damage him. LOL!
Chin na seems interesting, but being insecure, old female...too iffy to committ a lot of training. We do touch on PP in chisikunbo, but if was going to train kubotan would prefer sharpened ballistic plastic. Hubby showed rather effective use by driving it through attacker hand, and using it as lever.
Weapons make anything better.
