1. There are many styles of wine corkscrews - butterfly corkscrews, seahorse corkscrews, air pressure corkscrews and knife corkscrews, etc. When using a knife bottle opener, you should use a knife to cut the plastic cap on the bottle mouth, slowly drill the screw into the cork, then upright the screw, hold the bottle mouth with one hand, and slowly pull out the screw with the other hand come out.

2. Seahorse bottle opener: Press the back of the knife with your hand, cut 180 degrees counterclockwise at the bulge of the bottle mouth, and then 180 degrees clockwise until it is cut open. Then aim at the authentic cork, press down vertically, and rotate the wine knife clockwise. Remember not to drill through the cork, use the outer side of the horse's hoof against the mouth of the bottle, and lift the handle of the knife firmly until the bottle is opened. Do not take out the cork directly to prevent the sawdust from falling. Pull it out slowly.

3. Air pressure bottle opener: place the paper cutter at 90 degrees on the top of the wine bottle, rotate with the blade stuck to the bottle mouth, cut the foil, and then insert the bottle opener needle into the wine bottle from the middle of the cork, with a plastic protective sleeve Protect the bottle mouth; move air up and down to inject air into the bottle until the cork slides out from the bottle mouth (usually 4-7 times per bottle can be opened); then use the small plastic slider on the protective sleeve to remove the cork Exit from the needle.
