Our GoodCook Everyday Waiter s Corkscrew removes natural and synthetic corks from bottles of wine olive oil or vinegar. The serrated foil cutting blade glides around bottlenecks to remove the foil before removing the cork. The cork worm twists into corks for a secure hold and the two-step lever provides perfect leverage against the bottle to pull the cork out. All three fold-out features fold away for on-the-go-use and safe storage.
