Colorado viewpoint.
1. I thought doble edged blades put them into the "dagger" category, which were illegal on their own, independent of other super deadly dangerous implements and are therefore unsuitable for the commonfolk.
2. I bought my first autos real cheap about fifteen years ago from a Russian-owned dollar store just because of my fascination with them from the movie "Blackboard Jungle" and at the time they were illegal. Do not use too much force on the handle or the blade will pop out of alignment with the innards and that's all she wrote.
3. COmmierado recently legalized "switchblades" with some limitations on carrying and blade length, and I bought several so far from Smoke Shops, believe it or not. I was fascinated with the ones where the blade pops straight out (I forget the technical term) and I found that the larger ones are difficult to operate with my arthur-itis because of the strong double springing involved. I keep a small one on the end table next to the couch, which is really kind of fun. I carried it in my pocket for a while until I discovered that pocket lint kept it from operating until I blew out the crud. So I don't carry it any more, being content with a regular small folder for my pocket.
4. I'm not really a knife aficionado, e.g., it wasn't until a year ago that I discovered what "scales" were.
5. That's all I know. Oh, wait! Fig Newtons were named after a town in Massachusetts, not the scientist.
