A really awkward bottle & a corkscrew that wasn't up to the job were the cause of this new stroke of genius that has not been bettered since 1966. The patented system of the telescopic self-aligning cover always places the screw in the central part of the cork. The large screw in hardened steel with a wide & sharp profile provides maximum grip on the cork & the two large levers enable the corks to be pulled out of bottles of the finest vintages without disturbing the sediments that are typical of such wines. These technical features & the use of the finest raw materials have made this corkscrew a must, a symbol of genius that is recognized throughout the world.
