I was active and when I carried my butterfly knife, the only flak I got was a laugh or smirk. most times they ask if you know how to use it. One time I was told not to carry or use it but that e-5 was a dick any ways. all I did after that was keep it in my pocket around that person. As far as I know the base usualy respects the states law reguarding weapons. EI in NC it is legal to be 21 years of age and own a pistol. It's also legal for the registered owner to have said weapon in his or her vehicle so long as it takes more than 4 movements to gain access to and load the weapon. The base order states a service member in the barracks cannot have a weapon in the barracks. so we left them in our vehicles and were within perameters of all rules and regulations. Point being, bases usualy go by thier respective states law and all bases have their sepparate regulations. learn them all and stay in the guide lines. this way you can tell the E5 what to do next time they give you trouble. Another thing to keep in mind, a guy goes to the doc and says when I do this it hurts, the doc says to the guy, Then Don't Do That. don't play with your knife around some one that it pisses off.
