Children’s scissors are not anything as dangerous as they were back in the day. I used to run around with the dangerous pointy ones back in Second Grade (Circa 1974,75) I and none of my classmates never managed to stab anyone, while running around the playground during recess, NOR while we were doing paper Mache during the Arts part of the class. THIS IS NONSENSE!
Huh. Even when I was in second grade (circa 1956) we had the rounded tip type scissors.
Keep in mind that there's no such thing as accidents any more. If a child gets injured by scissors, a compass, ruler, anything you can think of, the teacher will be blamed, people will be outraged and everyone will use that as proof that schools are out of control. Another factor is that teachers can't hurt the l'il darlings feelings. A teacher can't say "Beatrice, you're going to have to sit alone at that table while everyone else uses scissors because last time we did you cut Sylvester's hair".
