A corkscrew is a tool designed to remove corks from bottles, primarily wine bottles. It typically consists of a metal spiral, known as the worm, attached to a handle. When the worm is twisted into the cork and pulled, it extracts the cork from the bottle, allowing access to the liquid inside. Corkscrews come in various designs, including the traditional hand-held type and more advanced models like the waiter's corkscrew and electric corkscrew. They are essential for wine enthusiasts and are often found in kitchens, bars, and restaurants, making the process of opening a bottle of wine simple and efficient.
