Abstract
A cork screw which comprises a pedestal and a rotary handle incorporating a stem and a penetrating screw wherein the pedestal incorporates a dog member to engage with a helical groove of the stem and a spring biased sleeve around the stem to cause the dog member to engage with the helical groove when the handle is turned in a certain direction and disengage therefrom when a cork is pulled entirely out of a bottle. A holding member is incorporated in the pedestal to hold a cork after it has been pulled out of a bottle.
