Wall Mounted Bottle Opener

Origin
A bottle opener is a device that enables the removal of metal bottle caps from bottles. 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 specialized lever inserted beneath the pleated metalwork, which uses a point on the bottle cap as a fulcrum on which to pivot.

Wall mounted works the same as the lever variation, except that it is attached to the wall, to allow for simpler bottle-opening, which can be done with one hand. The bottle cap can fall into a bottle cap catcher mounted below the opener, or you can retrieve it after removal from the bottle.

Today
Artie just happened to collect the bottle opener after coming across a video of people showing it off. Of course he snagged it before anyone could truly dispute the authenticity of what was being shown in the video.
