Razor sharp

Gawker writes a note to the guys selling razor blades on television.

… I would like to tender some advice to you regarding your television spot. Your attempts to convince me to apply your particular brand of sharp metal to my skin would go a longer way if you were not to illustrate the sharpness of that very same metal by demonstrating the remarkable ease with which it slices through tin cans, bibles and a variety of assorted vegetables, the raw consumption of which would leave one with sore gums.
