I hear all this talk about breaking down your shinai sand and oiling but I have no clue as to what you guys are talking about. Is it a wait and let someone show you how or learn while trying kind of thing. Not a single one of my team has ever mentioned it and frankly im dumbfounded about the concept of breaking down something IM GONNA HIT SOMEONE WITH. It would be my luck tying something wrong and breaking someones arm.

Ok basics ......
I know the parts of the Shinai, what kind of oil are you using ? is 10w30 ok ? (that was a joke) What about grit on sandpaper ? How do you know when is a good time to work it over ? And why shinai are cheap why not just get another one ?

any-who can someone help my noobish soul ...
