i have a hunting knife with an 8inch blade that i would like to keep in my truck. I keep in secured in a sheath, but I’m not sure of the California laws on hunting knives, and didn’t want to risk getting arrested.
Contrary to what you are going to see in a lot of answers, there is no general regulation of knives, other than switchblades, based upon length under California state law. (There are some laws applicable at schools and public buildings.) Under California law, this is a dirk or dagger, which means it would be unlawful to carry it concealed on your person. There is no prohibition upon carrying it concealed in a vehicle, so long as it is not on your person. (Pen C 12020.)
This is based upon state law. There may be some applicable local ordinances, you should check. I think those ordinances are unenforceable, but you don’t want to be the one to test that.
