California (Orange County) knife law?

State law would prohibit having that at a school or college campus, at an airport, or in a public building. Note that there may be applicable local ordinances. I find none in Fullerton, but Anaheim makes it unlawful to have a dagger (and this counts) while loitering. That law could be enforced. It is also unlawful to have one in a vehicle unless carried in good faith for uses of honest work, trade or business, or for the purpose of legitimate sport or recreation. That would seem to prohibit "just cuz I can." I don't think that law is enforceable, because the state has recently fully occupied this area, but no judicial decision has addressed the subject.

I don't know, but you just reminded me of the movie Orange County.

So funny...
