I'm thinking of going to my local sporting goods store and purchasing a small handheld folding knife. I think it will be good for protection and will come handy for outdoorsy stuff and possible emergencies. Legally, I'm pretty sure I won't be able to have it on school grounds (I won't be dumb and accidently bring it to school) but otherwise I'm pretty sure its legal to carry around a simple folding knife in my pocket. I'm also 18 and I'm sure the store will be able to tell me what laws there are, if any. Has anyone had any good/bad experiences with carrying a knife around or any suggestions, advice?
