Abstract: The industry-standard corkscrew has numerous flaws resulting in broken corks—even in the hands of a professional. The present invention is a radical departure from the traditional corkscrew apparatus. The opener generally consists of the handle and an internally threaded half-pipe. The half-pipe slides between the cork and the bottle, wherein the series of threads engage the cork. Rotating the handle causes the threads to bore deeper into the neck of the bottle until the handles meets the lip of the bottle, and then lift the cork out of the bottle until it disengages and falls away from the opener. It should be appreciated that the elegance of the opener resides in its simplicity.
