A long time ago, someone observed that whereas eggs are packaged in such flimsy cartons that care is needed to avoid breaking them on the way home, chisels are potted in such tough plastic that you need another chisel to get them out.

Until recently, a few brands of wine had a little tab on the plastic covering the cork so that you didn't need a knife to get it off. A small courtesy, but I suppose it made the malicious packagers grind their teeth. At any rate, they have all abandoned that design -- & lost this customer.
