i don't understand the shuhari either since i don't understand Japanese.

you meant i can't just sneaking up to my sensei with a tanto and jacking him for techniques. as in, "Your techniques or your life!" maybe i have gone at this all wrong, because i have tried technique jacking various teachers with bokken, jo and even empty hand. so far they kept saying "your life". i don't understand it. don't they know that i am technique jacking them? why can't they just hand it over to make it easy for everyone?

a bit off topic. if you jack someone named rob, would that be jacking rob, i.e. double jack, i.e. black jack?
