The Rabbit Wing Corkscrew from Metrokane was designed to overcome problems in the operation of conventional wing corkscrews. It clamps stably on the top of a wine bottle, which makes it easy to insert spiral into the cork. The non-stick spiral penetrates cleanly, so the cork will not crumble as often happens with ordinary wing corkscrew. It has an overall length of 20cm/8in and is dishwasher-safe. It also comes with a 5-year manufacturer's warranty.
