Duesenberg Patent Cork Screw

The official waiter's cutlery in Duesenberg style.
Here are the instructions for use, written by wine connoisseur Dieter G.: After screwing the spiral into the cork (not too far!), press the small spring-loaded snipper onto the bottle neck edge, pull out the cork a little and then put the corkscrew on the bottom.
So the cork can be pulled out with minimal effort. Ingenious!
