Okay, so yesterday I bought a spyderco endura (i love it) to be my EDC. Now I asked the guy behind the counter at Plaza Cutlery in Costa Mesa about the knife laws to make sure (I thought I already looked up on this) that I was in my legal right to carry a folder of any size. He tells me that I can only OPEN CARRY a folder but I can't carry it concealed. This got me nervous because I felt my purchase wasn't as good as it could have been. But it also contridicted with what I looked up online. So I recheck to make sure I wasn't wrong and sure enough it seems that I can conceal any folder in public and on public universities and colleges as well (but not k-12 schools not that i'm planning on going to one soon). Can someone absolutely confirm that either I'm wrong and he's right, or I'm right and he's a little behind the times or just plain mistaken. We're talking California knife law if you haven't figured it out yet.
