A corkscrew includes an elongate body, an auger pivotally mounted to the body, a first bearing arm pivotally mounted to the elongate body at a first distance from the auger, and a second bearing arm slidably mounted on the first bearing arm. The first and second bearing arms each have a shoulder, the shoulders being aligned adjacent one another. A connecting rod is pivotally mounted to the elongate body at a second distance which is greater than the first distance and pivotally engaged with the second bearing arm. During the extraction of a cork, the first bearing arm begins the extraction in engagement with the rim of the bottle neck. As the elongate body is tilted, the second bearing arm in turn engages with the rim of the bottle neck in order to take over from the first lever and fully extract the cork.
