My Dad contributed this little gem of information this morning:
Because glass is actually a liquid, it is never as sharp as when it has just broken. Because liquids flow, and pull themselves into round through capillary action, the edge will immediately begin flowing back onto itself, blunting and widening and rounding to a smoother point. Even 20 minutes later, apparently, according to my Pa, it won't be nearly as sharp as it had been when freshly broken.

Your father is a wise man. And you are too, to recognize it.
