Abstract
A self-pulling cork extractor having a guide and a corkscrew which may be stored entirely within the guide for compact and safe storage and transport. The corkscrew includes a worm having a sharp free end attached to a handle having downwardly and inwardly foldable end portions. The end portions are upwardly and outwardly extended and the corkscrew is positioned within the guide with the free end downwardly oriented for extraction of a cork, lateral movement of the corkscrew being limited by an aperture located at the top of the guide. For storage and transport, the end portions are downwardly and inwardly folded and the corkscrew inserted upwardly through the lower portion of the guide and retained completely therein. In the storage position, the sharp free end of the worm is positioned within the aperture at the top of the guide, thereby preventing the exposure of any sharp edges or points. A foil cutter is also integrally formed in the guide.
