Abstract: A sommelier's corkscrew having an elongated first shaft (1) hingedly connected at one end with a second shaft (2) including a tool (2.1) for opening crown caps and an extension (2.2) having a formed step adapted to engage the top edge of a bottle mouth during the corkscrew lifting step, and a helically shaped third shaft (3) hingedly connected to the first shaft. The corkscrew further includes a mechanical element (10, 20) adapted to engage the third shaft and actuate it automatically to move the third shaft from the closed position of the corkscrew, where the third shaft is contained between the first and second shafts, to the open position where the third shaft is substantially perpendicular to the first and second shafts aligned in the open position.
