We all carried little pen knives...to play mumbly peg.....and I’m talking kindergarten...and up. It was no big deal. We were very responsible kids and our parents knew what we were doing all the time.
Nobody ever got hurt, and none of us would ever have imagined shooting each other or anyone else. I can't claim we were exactly responsible, but we all had a good idea of how dangerous our "toys" were and practiced as much safety as 14-year-olds are capable of mustering when there are no adults about.
