When you’re trying to break the perforated cardboard on a 12-pack of Diet Coke, and they just won’t break open to your fingers, I know your first inclination is to look around the immediate area for something harder than your fingers.  You want something tough and sharp, with which you can break the perforations.  The fondue fork laying on the counter is *not* the appropriate tool. Unless your goal is bathe your face in a refreshing spray of Diet Coke. Don’t ask me how I know this. Just take it on faith.
