Maybe they are linked in a way I don't understand?
(Other definitions for corkscrew that I've seen before include "Spiral device for wine lovers", "Wine bottle opener", "Bottle-opener", "This might help one who gets in the drink", "Move in a spiral manner", "Bordeaux might require this?", "Twist", "Opener", "Bottle opener" and "Graves opened by this".)
