Billed as “the smallest fully working corkscrew in the world,” this cool little TwistStick Corkscrew device will keep any wine lover from ever being without the means to open a bottle. (If you’ve ever faced a time where you’ve got a full bottle of wine and no corkscrew, you know this is a sad situation.)

Being the length of my pinkie (66 millimeters to be exact) but far thinner, this handy little corkscrew is about as unobtrusive as it gets as a keychain. Ingeniously simple in design, the twisty part wraps around the shaft. To put it into action, you just remove the keyring part at the end, pull the twisty part off, and put the shaft part into it.

In my tests with two real bottles of wine from Chile—a tough job but I had to do it—this TwistStick did the trick without much effort. I tried it on a bottle with a real cork and a bottle with one of those impossibly hard, non-biodegradable plastic ones. Success in both cases.

Granted, this isn’t quite as easy to use as one of those technologically advanced Rabbit Corkscrews or even a good waiter’s corkscrew with some leverage, but this is a whole lot easier (and lighter) to carry with you.

The obvious question for travelers though is, “Can I carry this onto an airplane? Well, there’s a chance you could get away with it, but an equal chance that it will get confiscated. So I wouldn’t advise it. Limit this to when you’re checking a bag or traveling by other means.

The manufacturer, True Utility, makes all kinds of other cool keychain gadgets. They’re based in the UK though, which means this product is easier to find in Europe than here. You can get it through third parties at Amazon though for 10 bucks.

Or get it from Amazon UK for under 5 pounds.
