If you're a big wine drinker, I think you'll particularly appreciate the Corker by Sebastian Bergne. This three-pronged corkscrew only becomes complete after you've had a couple bottles of wine. Although it doesn't encourage overdrinking (wink, wink), it is made for the wine connoisseur.
The Corker by Sebastian Bergne requires two wine corks to create a unique handle. This also helps you remember what you drank last so that you can always try something new.
