‘Waiter’s Friend’ Corkscrew
A waiter’s friend, sommelier knife, or wine key corkscrew was conceived in 1882 by Karl Wienke. This slim, foldable, corkscrew is in a folding body similar to that of a pocket knife. It utilises a screw and a single lever, due to an arm that uses the body of the bottle for leverage to ease the upwards pull of the cork. Whilst this style was patented in Germany, America and England, the Dutch are renowned for their quality silver pocket corkscrews.
This style was invented by Domenick Rosati in 1930, and afterwards utilised by multiple brands to accommodate the growth in popularity of the wine market. The winged corkscrew has multiple aliases:
This form has two levers which rise as the worm is embedded into the cork. Pushing down the levers allows the cork to be retrieved from the bottle in one smooth motion. This form is especially effective when crafted out of heavier, thicker metals such as silver.
The lever (or ‘rabbit’) corkscrew is operated using a pair of handles which grip the neck of the bottle. A lever is pressed down to twist the screw into the cork and then lifted to extract it. Whilst this style of corkscrew is often rather expensive, it is far more efficient than other styles.
