This is the single best invention we have seen for opening old bottles of wine with long and fragile corks! It is a combination of an Ah-So style opener and a worm. Between them, they reliably work together to grab the cork, and remove it intact. It is hand-made in the U.S., from a design by Mark Taylor, and named to honor Sommelier Yves Durand. It is not cheap. But if you are opening a priceless old bottle, it is well worth it to have an intact cork come out of that cherished wine bottle. We swear by it for old Bordeaux, Burgundy or California wines! Nothing is perfect, and no one bats 1000, but this device comes as close as we have encountered.
