Why my I ask do you want to be original in drawing the sword to cut down an aggressor?
It's like asking if there is any originality in a SWAT team course.
These methods require drilling and adhereadnce to proven life preservation skills. Otherwise, you DIE.
Are you confusing this with kenjutsu, the art of sword play, or kendo, the sportive and ritualised form of sparring with replica katanas.
Kendo and kenjutsu are pretty rigid. You are not learning to fight with them, you are learning a weapons system so yo can use it to fight. Like a soldier learning to use his M4 carbine. You are adapting to the technology to get a job done. More so, kenjutus was taught to regiments of soldiers. Hence the mechanical method of teaching (formation teaching, all right handers).
European fencing, using the sabre is fairly unrestricted. The foil and Epee have restrictions on target areas etc. I say this because this sounds more like your interest.
