Superb performance. Rigorously tested. Much admired. This masterful piece of engineering takes opening a bottle of wine to new heights. A 21st century redesign of the original Herbert Allen lever corkscrew, its innovative rotation technology makes light work of any cork. Effortless and easy to use, once the screw is wound into the cork, you'll just need to keep turning in the same direction and the cork will be pulled free. The cork is then easily released by simply turning anti-clockwise.
