In addition, we try to make sure that the corkscrew is easy to use, well-made, and rugged. Most corkscrews we sell have been in production for at least a few years and their reliability is now well established.
Most corkscrews are ready to go.
The reason is that, in advance, you need to position the tip of the worm at the bottom of the frame, so that the frame can help you guide the worm into the cork. Opening two or three bottles is usually all it takes to get the hang of it. A worm that is not in the center of the cork or has been inserted at an angle is probably the most common cause of shredded corks or broken worms. If the cork is brittle, a worm penetrating the bottom of the cork might leave annoying bits of cork in the bottle. Fortunately, most contemporary corkscrews have such a strong, fine point worm that they can pierce most corks without crumbling them.
