1. First, insert the auger into the middle of the bottle opener facing the cork.

2. Turn the handle slowly and drill the cork down. When doing this, keep the bottle opener vertical and do not tilt.

3. Continue to turn the handle until the wings rise to a high point and stop.

At this time, we hold our wings with both hands and press down hard.

When the cork comes out of the bottle, we can turn it out slowly along the line.
