So I was being talked to by a DEA fella about a certain family member in a public place in San Jose,CA and of course they ask if I have any weapons on me and I do, a Spyderco Endura. After he's done searching for any other weapons on me he flips opens the Endura with his wrist and tells me it's illegal to carry a knife in California if it can be opened just like the way he did. Now the pivot hasn't been loosened by me for any reason, if anything I have tighten it because the pivot screw was getting loose but no different from being stock from factory except it's been used. So after a little while at the end he says he can take the knife and destroy it or give it back and give me a ticket for a misdemeanor. I said fine take it but I want a receipt/note saying he took the Endura which I thought the had to give if asked when confiscating anything from you and he tells me he doesn't have any to give me. Was I in the wrong cause I can flip open all my knives or really any knife I have handled in my experience with my wrist? Or was he not being very nice?
