Butterfly Opener:

    1. First point the corkscrew to the middle of the wine cork that has been opened.

    2. Rotate the door handle at the top of the bottle opener and drill the screw plug into the inside of the cork. Take care to keep the auger down straight and not necessarily through the cork. At this time, the door handles on both sides will be stretched further and further due to the drilling of the auger.

    3. Close to the bottom of the cork, after the bottle opener wings are stretched out, press down the two wings with both hands, and the bottle cap will open with it.
