Replying to Compass

There's a compass on my desk - you know, the things used for drawing circles - and now that I think about it, they're pretty sharp. How can these be acceptable for little kids to use at school? What's stopping them from hurting themselves or stabbing someone or something? I mean, people say not to run with or throw scissors, but to be honest, I think that compasses are way more dangerous. Should we make this a public concern for our country's schools?
