In my early school years, we only had round tipped plastic safety scissors that could barely cut tissue paper. As a kid, I was terrified at the degree of responsibility and potential to take another kid's life those scissors represented.
The adults in charge when I was a kid had us convinced that if we ran with scissors in our hands we were going to kill the other children in the vicinity by accident in the most horrifically bloody and violent manner. They even showed us video re-enactments of children getting stabbed in the heart, neck, and eye complete with fake blood gushing out and Bugs Bunny worthy death performances.
A lot of us thought this was some super common way that kids were dying by the millions all across the world.
