I'm very upset. When people carry Mace or some other pepper spray they are considered prepared and they have it just in case. When someone carries a knife they are considerd dangerous and paranoid. Knives are much more usefull. Try cutting a burger, openning a package or trimming a thread from your jacket with pepper spray. They can also be used for self defense. I hate being labled paranoid because I carry a knife. Am I just running my mouth? What do you guys think?
