This invention relates to a corkscrew (1), of the first-class lever type, designed so that once the screw (3) is driven into a cork (10) that is fully inserted into the neck of a bottle (12) and that free end (8) of short fulcrum (5) is placed on the bottle lip (11), a single hand (14) can hold the bottle neck (12) and the free end (2') of the lever (2) simultaneously. A squeeze of one hand (14) will bring the free end (2') of lever (2) against the bottle neck (12). The cork (10) is now raised an initial distance from its original position. The operation is repeated using long fulcrum (6) whose free end (9) is placed against the bottle lip (11). In this second position the free end (2') of lever (2) and the bottle neck (12) are again within range of being grasped with one hand (14). A second squeeze of the hand (14) now moves the cork (10) the rest of the way out of the bottle neck (12).
