Put the bottle on a table or flat surface and remove the foil. If the bottle doesn’t have a pull-tab that allows you to remove the top of the capsule (foil covering), you can do this either by pulling the entire capsule off, or by using the built-in knife on the side of the corkscrew to trim around the perimeter of the foil right above the lip on the bottleneck.

Next, carefully extend the lever (double-hinged part) and extend the worm so that it forms a T-shape with the handle. Holding the bottle with your nondominant hand, use your dominant hand to center the tip of the worm in the middle of the cork. Twist the worm clockwise (for most models) into the cork until the last loop is just above the top of the cork, trying to keep the worm straight as you do so.

Hook the first notch of the lever (the hinge point closest to the handle) on the neck of the bottle. Bracing the whole lever against the bottleneck with your nondominant hand, pull up on the handle with your dominant hand until the cork can’t rise any higher. Then hook the second notch (the hinge point at the end of the lever) on the neck of the bottle and repeat the motion. The cork should slide out cleanly. If it’s still slightly stuck, gently wiggle the cork from side to side, pulling upwards slightly until it pops out.

Finally, to remove the cork from the corkscrew, hold the cork in your nondominant hand and twist counterclockwise (for most models) until the worm exits.

If the cork breaks in the bottle, take the corkscrew out and remove any pieces of cork that are stuck on it. Then, insert the worm into the remaining cork at a 45-degree angle, twist it in, and then carefully coax it upwards, using the appropriate notch for leverage. If the cork is a total goner, or starts to crumble when you make the second attempt, just push it into the bottle. You can then pour the wine through a triple layer of cheesecloth, a coffee filter, or even a fine-mesh strainer to remove any debris before drinking.
