Corkscrew

In its traditional form, a corkscrew simply consists of a pointed metallic helix (often called the "worm") attached to a handle, which the user screws into the cork and pulls to extract it.

Corkscrews are necessary because corks themselves, being small and smooth, are difficult to grip and remove, particularly when inserted fully into an inflexible glass bottle.

The design of the corkscrew may have been derived from the gun worm, which was a device from at least the early 1630s used by men to remove unspent charges from a musket's barrel in a similar fashion.

[3][4] In its traditional form, a corkscrew is simply a steel screw attached to a perpendicular handle, made of wood or some other material.

The head of the central shaft is frequently modified to form a bottle opener, or foil cutter, increasing the utility of the device.

[5] The first American patent was in 1930[6] granted to the Italian Domenico Rosati[7] who emigrated to Chicago, Illinois, to work as bartender before the prohibition.

A small hinged knife blade is housed in the handle end to be used in cutting the foil wrapping the neck of many wine bottles.

The term "wine key" came into existence due to the German inventor's last name, Wienke, which is difficult for English speakers to pronounce.

When ordering the product from catalogs, the meaning and origins of the new Wienke Corkscrew gradually became lost and it was simply referred to as a "Winekey" or wine key.

The mounted corkscrew was invented in the late 1800s for use in homes, hotel bars, and restaurants in an era where all bottles were stopped with corks.

The Screwpull wraps around the top of the bottle, with a plastic screw that simply needs to be turned to remove the cork, without effort.
