What is a "corkscrew"?

A corkscrew is a handheld tool used for removing corks from bottles, typically wine bottles. It typically consists of a metal spiral, with a pointed end for piercing the cork, attached to a handle or lever. To use a corkscrew, you insert the spiral into the center of the cork and then twist it into the cork until the spiral is fully inserted. Then, you use the handle or lever to pull the cork out of the bottle, using the leverage to ease it out smoothly. Corkscrews come in various styles, including simple handheld models, waiter's corkscrews with fold-out handles, and electric corkscrews that automatically remove the cork with the press of a button.
