Definition: limonadier corkscrew

Its ergonomic design, durability and ease of use, as well as its three functions, make it an essential tool for sommeliers and private individuals alike. It is primarily a corkscrew whose double lever multiplies the force for the first extraction, then allows the cork to be removed completely without having to insert the screw again.
Once the bottle has been uncorked using the slightly serrated blade, simply push the screw in, taking care to pierce the cork in the middle to avoid crumbling a cork that is too dry. Once pushed in, simply press down on the neck of the bottle with your thumb and lift to the height of the first lever.

As soon as the cork is extracted and you reach the end of the tool's extension, lift the bottle opener to place the lever in its second position, resting on the neck of the bottle. This allows the cork to be easily removed without having to use force.

The third use is as a bottle opener for all kinds of crown caps on beer bottles and other soft drinks.
