The invention relates to a corkscrew comprising a spiral ( 10 ) that is rotationally mounted inside a sleeve ( 28 ), which can be placed on the neck of a bottle, or is rotationally mounted between at least two corresponding limbs that can be placed against the neck of the bottle. The corkscrew also comprises a driving shaft ( 15 ) whose rotation actuates the spiral ( 10 ) connected thereto. In order to be able to actuate the corkscrew with a distinctly reduced expenditure of force, a reduction gear ( 12, 13, 14 ) is mounted between the driving shaft ( 15 ) and the spiral ( 10 ).
