It seems to me a knife is a knife. Why ban any of them? But even still, I can’t see criminal charges against a mistake. Fire them. Don’t arrest them.

Well, that’s a good question. I don’t know the answer. Spring-loaded knives became popular after the Civil War with amputees. WWI too. They became illegal after WWII because of the same teen hysteria that tried to ban comic books.
