Bottle opener
A bottle opener is primarily thought of as a device which enables the removal of metal bottle caps from bottles, though more generally it might be thought to include corkscrews used to remove cork or plastic stoppers from wine bottles.
A metal bottle cap is affixed to the rim of the neck of a bottle by being pleated or ruffled around the rim. A bottle opener is a specialised lever inserted beneath the pleated metalwork, which uses a point on the bottle cap as a fulcrum on which to pivot.
There are a couple of distict designs of such bottle openers. Wall mounted openers are typicaly found in behind bars in pubs, whilst hand-tool bottle openers tend to be found and used in domestic environments. Whereas the functional elements of bottle openers tend to be consistent, their aesthetic design is subject to very great variety, and a great many decorative types are available.
