Thanks, I had CA in mind because I was born and raised there, brass knuckles and some knives fall in the same category as nightsticks as well.
Billy clubs, brass knuckles, and even switchblades are legal here as a result of that decision, but a significant portion of the ruling was devoted to a series of twisted rationale to avoid it's application to most modern firearms (though I am hoping the upcoming incorporation and it's definitions will force a revisiting of that issue).
