Step-by-Step Instructions: Cut the foil under the lip of the bottle with the foil cutter, so that the cork can be extracted. Unfold the worm so that it is perpendicular to the corkscrew handle and vertical and place the tip on the cork. Twist the worm into the cork, without piercing the other end. Hook the bootlever notch on the bottle’s lip and hold it in place with your index finger, while firmly holding the bottle’s neck with the other hand. Lever the handle up with the other hand to extract the worm and cork. With a double notch or double trigger waiter’s friend, lever the handle up until the cork is halfway out of the bottle. Then hook the second bootlever notch and repeat the motion until the bottle is open.
