I think they might see the writing on the wall. The fact that California is so anti-gun, how far behind are they from being anti-knife?
They're already horribly anti-knife: no automatics in home or in public, no carry daggers, no pen knives, can't carry anything over 4", with the rules varying widely from jurisdiction to jursidiction.
Carrying a knife in California is a very iffy proposition. What's legal in your county, may be illegal in your city. What's legal in your town may be illegal in the next town over. Never carry one of those pocket clips knives; you'll probably be safe, but it can also get you arrested real fast.
