VacuVin WineMaster actually locks on to the wine bottle - place the corkscrew on the neck of the bottle, pull down firmly and WineMaster locks onto the bottle! One set of levers inserts the spiral into the cork, and the other set lifts the cork. Raise all the handles up simultaneously to release the cork. Includes Foil Cutter. Clear, with an intriguing view of the gears at work! Made in The Netherlands.
