he is heavily qualified in other (non jewish) arts.
If he does have a tradition, it is very broken, and it seems be is really using the non jewish arts, removing any idolatry, and giving them a jewish dash of paint. reshaping those arts somehow, using hebrew letters and concepts
i saw a thread in a forum where somebody posted a clip of this guy doing something with a sword, as if it is uniqique to the Abir system. And he guy posted a clip of some other guy doing the exact same thing - not Abir.
It is just like an oriental martial art
If the oriental martial arts were so great, then i think we would see them in UFC more. UFC has highlighted that to fight well you need standup skills - like boxing. And ground fighting skills, like jiu jitsu.
