I'm from Washington state but moved to Massachusetts for college. However, i practice martial arts and use nunchucks for demonstration purposes and was wondering what the laws in Massachusetts were. I heard somewhere that it is illegal to carry nunchucks yet it was okay for them to be kept in the martial arts school, but i'm not very positive on this subject. If someone could please explain whether or not i can use them for demonstration purposes or if i cannot posses them at all, that would be great. Thank you
