Despite their name, these corkscrews have not actually been known to take flight. Winged corkscrews provide lever-action mechanisms on both sides, which seem to resemble wings. Pulling down on these wings takes very little effort, making it easy to withdraw the cork from the wine bottle. Winged corkscrews are very common. These corkscrews give the user the advantage of a base that lines up over the mouth of the bottle, providing a precisely centered entry point for the metal screw itself. The top of the winged corkscrew is a turning handle by which the user can literally screw the spiral into the cork. As the screw goes further into the cork, the wings raise up. When the screw is in all the way, the user needs only to push the wings down, which pulls the cork out of the bottle. Winged cork screws are arguably one of the most traditional corkscrews, but they are available in contemporary styles to suit upscale, modern applications. They are also popular choices for home use.
