A corkscrew is a tool used 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, it allows the user to pull the cork out of the bottle easily. There are various types of corkscrews, including the traditional waiter's corkscrew, the lever corkscrew, and the electric corkscrew. Each type has its own mechanism for extracting the cork, but all serve the same basic purpose: to open bottles without damaging the cork or the bottle itself.
