A Wing CorkscrewFirst invented in 1932 by the Spanish industrial designer David Olañeta for his brand BOJ (and later adopted by other brands.), a wing corkscrew, sometimes called a butterfly corkscrew or angel corkscrew, has two levers, one on either side of the worm. As the worm is twisted into the cork, the levers are raised. Pushing down the levers draws the cork from the bottle in one smooth motion. The most common design has a rack and pinion connecting the levers to the body. The head of the central shaft is frequently modified to form a bottle opener, increasing the utility of the device. Corkscrews of this design are particularly popular in household use.Working The main lever is rotated downwards into a cork and is driven inWe then use the wings and push them upwards to pull the screw out The cork comes out of the bottle with the screw
