Similar to a long staff form I know form Wang shu chin tradition. I learned it from a guy who claimed he didnt know the liniage but some taiwanses students recognised it let me know if you want to see it
I have two things that he should work on. I know this is Bagua and not Katori Shinto Ryu but to get the most leverage out of out of you staff have half of your pinky finger hanging off the back of the staff and bring it to you forhead or someone could knock that thing right out of your hands. I would like to see some one from katori shinto ryu learn this one
