Brand name of a special corkscrew, whose helix (spiral) does not pierce the cork compared to conventional devices. According to the manufacturer, this prevents disturbing cork crumbs from getting into the wine. By means of a handy ball, the Teflon-coated spiral is turned only approx. 35 millimetres into the cork and the cork is then unscrewed in the same direction by means of a toggle located under the ball. According to the manufacturer, Corkyboy also works without problems with all plastic corks. This is one of the many variations of a bell corkscrew. The circular part at the left end is a foil cutter.
In the past, you needed a wealth of encyclopaedias and specialist literature to keep up to date in your vinophile professional life. Today, Wine lexicon from wein.plus is one of my best helpers and can rightly be called the "bible of wine knowledge".
