Easier removal of stubborn corks: double the leverage thanks to two levels. Level 1: Push in by turning and pull half the cork out of the bottle. Level 2: place the next opening level of the corkscrew on the neck of the bottle and remove the rest of the cork using the same leverage again. With twice the leverage, you can remove even old and brittle corks or corks that are firmly in place without damaging them, gently and without damaging them. So with this professional sommelier's corkscrew you can open any bottle of wine elegantly and effortlessly.
