A really awkward bottle and 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 and sharp profile provides maximum grip on the cork and 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 and the use of the finest raw materials have made this corkscrew a must, a symbol of genius that is recognized throughout the world.
