Rabbit corkscrews are used for opening wine bottles. The corkscrew is manually screwed into the cork at the top of the wine bottle for a few turns. Once it has gone in an inch or so, the levers or rabbit ears are pressed down. This pulls the cork out of the wine bottle.
A New York based company Metrokane is the manufacturer of Rabbit corkscrews. Rabbit corkscrews come in different varieties and the price of a pack of rabbit corkscrews range from $35 to $49 (pl see URL- http://www.amazon.com/Metrokane-Rabbit-Corkscrew-Foilcutter-Silver/dp/B00005NPHL for example)
