“Worst cork screw ever”

“I bought several of these packages. The small Swiss Army knife is great; however, the waiter's tool is poorly designed and very poorly manufactured (burrs, etc.). The key design flaw is that the part that rests on the neck of a wine bottle is oversized and shaped in just such a way that it applies too much force to the glass when you lift the cork, causing the glass to break. I have several other brands of similar tools; none of them have this problem. It seems a shame to have to throw even a small steel object away, but this one is dangerous.”
