My wood shop teacher back in seventh grade made his point the first day of class -- holding up his hand with one-and-a-half fingers and a thumb and saying, "These saws are perfectly safe..."

This is a pretty amazing invention. And it's not necessary for it to work for a number of times -- as long as it works the one time it's needed. Definitely not an excuse to not take safety precautions or let your attention lapse for even a nano second.
