Yep, CA knife laws are very strict!
Double edged knives are illegal here in California. They're very restrictive about concealment as well. For instance, you can only carry a knife if you are hunting, backpacking or other similar activity that would need one if the situation arises.
Are you serious?
Double edged knives are NOT illegal you however can NOT carry them concealed.
You CAN carry a knife on your person while not hunting, backpacking, etc too.
I suggest you read the CA Laws before spouting out incorrect information and realize that some crazy laws are only for you "SoCal" La County people.
