I'll be visiting the LA area. I'll be in the city and outside of the city as well, and I'll also visit some of the towns nearby. I've checked the internet for advice on knife carry in CA, though not very thoroughly. It seems that I need a 3" or shorter blade, and I need to have it completely concealed (no clip showing). Is that correct?

I feel like I need to check with some of our California residents, because I recall the news story about someone going to jail for carrying on his person some sort of pointy thing while hiking, which is apparently a crime. (On the other hand, if he had it in his bag, he would have been fine.) So if I go hiking, should I make sure to have a bag with me, and to put the knife in the bag?

Thanks.
