What is a Corkscrew?
A corkscrew is a small kitchen gadget designed to remove the cork from a bottle of wine. The most basic corkscrew model consists of a metal spike in the shape of an open spiral (helix) connected to a wooden handle. The user centers the point of the helix on the top of the cork and twists until the wire has become securely embedded in the body of the cork. Securing the bottle with one hand, the user then pulls on the handle until the cork has been released. The cork can then be removed from the corkscrew and examined or discarded. Wine experts estimate that pulling a cork out of a bottle with a corkscrew requires the same force as lifting 100 pounds. For this reason, many mechanical improvements have been made to the traditional corkscrew design. Some provide more leverage for pulling out the cork, while others emphasize more torque during twisting. Waiters who routinely open and pour corked wine bottles carry a simple lever corkscrew.
