Yeah...it's pretty funny. For a while U.S. Customs were seizing assisted opening knives, which by definition aren't switchblades, gravity knives, etc. UK knife laws were the reason Spyderco designed the UKPK, which is actually one of my favorite knives of theirs. It was initially only for sale in the UK market, which prohibits locking blades. One thing I've come to discover in my almost 34 years of life, and 11 years in law enforcement; legislators and common sense rarely have anything to do with one another. Criminals, by definition, don't obey the law, so laws only affect the law abiding. The AKTI (American Knife & Tool Institute) is a great resource for researching law and legislators, as well as pending legislation affecting knife owners. The anti-knife crowd, while less visible than the anti-gun crowd, is just as active, and just like the anti-gun crowd, exhibits an admirable lack of common sense. And just in case those out there reading this think this doesn't affect you; a razor is a knife. The fact that it has a very specialized use just gives the anti-knife crowd more reason to go after it. They can't really attack your steak knife, but they can your razor, since it can be used to cut and attack people (ask any old-time prostitute) And I feel about my knives the same way I, and many others, feel about my/their guns: They'll have to fight me, and beat me, to get them. In LA, the only knives I'm aware of that are illegal for the average citizen to carry are auto-opening knives, folding knives with blades over 6" (OAL over 12"), and fixed knives with blades over 12". That's just off the top of my head...there may be more I'd have to research a bit. There isn't, as far as I know, any type of restriction on the type of locking mechanism...of course we have a Democrat governor, so that may change. Not that there's a huge difference between a Democrat and a Republican when it comes down to it. Both are whores who bribe people with their own money. The difference seems to be that Republicans want to control the way you behave, and Democrats want to control the way you think. Ok, enough ranting.
