I'm lucky and my local laws allow for such knives to be owned and carried, but why do so many jurisdictions disallow so much as having the knife at home and not even carrying it yet any folder with a thumb stud or spyderco style hole will open much faster and more reliably? I've heard different things from different places. My main theory doesn't have so much to do with deployment speed or lethality so much as the "bali-bite" that people who aren't used to them get when they jump in without a trainer to get better. I am avoiding the trainer for a specific reason, I don't want to develop a bad habit on the trainer and get bit the first time I flip one. I just start slow and work my way up. What are your thoughts on why so many areas have outlawed these knives now that you've heard mine?
