Im 16 and carry I Benchmade 705BT on me out of school with no problems 99% of the time. If I am bothered usually explaining that I am an Eagle scout and a Boy Scout instructor of knife use and saftey calms people down. I've never taken it anywhere with a metal detector (for fear of losing a $140 knife), however I have gone through many places with the small SAK on my keychain no problem.
