Yep - it also goes out of its way to mention "fixed blades". I can't speak to the Kurgan Sword, and that had occurred to me after I wrote my initial post, actually, but like I said, many states have these laws. And it doesn't really matter where the spring mechanism is. It's a cosmetic feel-good ban. Just like the old assault-weapons ban that has thankfully died a well-deserved death - banning rifles with bayonet lugs, folding stocks, two-piece grip/stocks, threaded muzzles; these are all cosmetic things that have no overall impact on the function of the weapon. They just made the guns "look" evil. Same mentality behind the ban of spring-loaded blades. I had to go to Tiajuana to actually find a switch blade back in 1991.
ONE EXCEPTION, however, that I just now recalled. Spring loaded blades may be shipped to a customer disassembled. It is at the customer's own peril to assemble the blade to make it illegal. The loophole being, the individual component parts aren't illegal, merely the sale of a completed assembly. That's probably how they got around the Kurgan blade. Maybe someone who purchased one of those here on the board could elaborate. You can buy parts for an AK-47 or AR-15 that would make it fully automatic, so long as you don't put them into the receiver assembly. Once that happens, it's considered an unregistered Class III firearm and if the Bureau of Alcohol, Tobacco and ****kups finds out about it, you'll be going bye-bye for a very long time.
Aren't these laws absolutely retarded? Your tax dollars at work...
