In a pocket corkscrew, a handle 1 is pivotally operated around two fulcra (4, 6)-around the first one (4) during a first run of the cork (14) and around the second one (6) during the second and definitive run of the same cork. Increase of the arm 2-4 into the arm 2-6 allows the cork (14) to run a further path d2, avoiding a second screwing of the extracting means 3.
