Because I can't carry a gun.
Because I am an Eagle Scout and have carried a knife and zippo since age 14 (I think). I remember getting on the school bus one morning. My dad ran out of the house yelling my name. As it turns out, I forgot my knife on the kitchen table. haha.
Back in middle school I got suspended for 5 days because I had left a small pen knife in my jacket from over the weekend when I was fishing and it fell out when I went to put my coat on. It was like the scene in the movies where everything stops and the music screeches to a halt. I thought my teacher was going to have a stroke. All over a tiny pen knife.
