1. The first step is to cut off the wine cap. Use the serrated knife of the bottle opener to cut the tin foil protecting the mouth of the wine bottle at the edge of the bottle mouth. Generally, use a forehand knife and a backhand knife to cut the top of the tin foil cleanly and quickly.

2. In the second step, use the screw to screw in the wine stopper. Open the screw part of the corkscrew and align the center point of the cork.

3. In the third step, press the end of the screw of the bottle opener down with your index finger, press a small part of the end of the screw into the wine stopper, straighten the screw, and start to rotate it downwards. Be careful not to drill the whole screw in. Wine corks are inside, and a small portion is usually kept outside.

4. The fourth step, use the lever to open the cork. Use the lever of the bottle opener to clamp the first-level lever on the bottle mouth, hold the lever and the bottle mouth with the left hand, and press the bottle opener down with the right hand; when the wine cork is partially pulled out, use the second-level lever to be stuck on the bottle mouth .
