Puritanical aspect to sharp curbstones

To the editor:

Another interesting world of wonder insert was in the Sunday, August 21 Eagle. It featured the Stone Age. The illustrations of sharpened stone tools reminded me of the controversy over sharp curbstones and the expensive damage new curbstones cause.

The Massachusetts DOT does a good job of installing rounded guardrails and break-away, streetlight stanchions, but the sharp curbstones endure. I speculate that a Puritan heritage quarry provides free curbstones to Mass DOT as long as they are honed to a sharp, upright edge. Is the edge there to remind wayward humans to stay on the "straight and narrow," or suffer "the wages of sin"?
