Shuriken are more about skill than anything else. Even if someone like Govener Ah-nold throw one as hard as he could, a 140lb Japanese guy who'd trained his life throwing shuriken could easily or distance him and throw it with more force. So maybe STR. with shuriken is the amount of skill the person has with throwing them.
