Does anyone know anything about the CA knife carry laws? Specifically, I'm interested in knifes in a sheath worn on a belt. What's legal/what isn't? I'm fairly certain what they are for pocket knifes, but feel free to post anything about that too.

I used to wear a sheathed knife whenever camping but haven't really done that since having a good EDC pocket knife. I never really cared or worried about it while camping or out in the wilderness, but I'm interested to see what the laws are concerning haveing them just around town.
