In California carrying a fixed blade is a very iffy thing unless you carry it "openly" on your belt. If you conceal it in any way (on your person) it is illegal. Concealed in your car is not on your person and is perfectly legal. There was a recent case in Los Angeles where a man was arrested for having 3 fixed blade shuriken throwing knives in his backpack. He fought the charges and his conviction was repealed. It was found that "on his person" does not apply to a backpack or briefcase or other containers that one carries. I just wanted to let any members here that live in California know that it is perfectly legal to conceal a fixed blade in a backpack or other container such as a tackle box or briefcase or anything that is not part of your clothes.
Please still be cautious as Los Angeles, San Francisco, and Oakland all have there own blade length limits when it comes to knives. Also know that many police officers might not be aware that concealing a fixed blade in a backpack is legal and you might still get arrested until they figure it out.
I just wanted to give you guys a heads up.
If anyone has a legal question about California knife laws feel free to ask me. I am in no way a lawyer so do not take my advice as such. I am well versed in California knife laws though and will always give a link to a Penal Code or Case to backup any information.
Just a thought. (ohhh.. no)

Why do we not have a legal section?
PEOPLE v. PELLECER
http://www.leagle.com/decision/In%20CACO%2020130417044I forgot to add this, but will now. Carrying the shuriken throwing knives is still illegal, but they could not charge him for that.
