IIRC, Kali law was they are illegal, unless you are a martial artist, practicing inside a dojo, or some such garbage. At one point you might have had to qualify as some sort of expert, i.e. black belt to have them.
I enjoyed them, and we bought all kinds of trick ones. My favorites were couple of tubes of metal that interlocked into one stick, twist it, and it came apart, with a piece of steel cable for a rope. VERY cool, and, not a joke.
Really way too much time on the legislatures hands. Cut them in all states to 3 months, and then they wouldn't have time to pass all this stupid stuff. Same thing for Congress...
