A corkscrew is a tool for removing corks from bottles, particularly wine bottles. It usually consists of a pointed metallic helix (the 'worm') attached to a handle. The user twists the worm into the cork and then pulls the handle to extract the cork. There are various types, including winged corkscrews and lever corkscrews. It's an essential tool for wine enthusiasts. You might find these in restaurant venues.
