Equipped with a five-turn. elongated conical spiral, micro-serrated knife blade with fingernail grip and cap lifter. An additional feature that makes these corkscrews special, are the two adjustable axis connections. One at the spiral connection and the other at the boot lever connection. A special two-sided wrench (included) allows you to loosen or tighten the tension needed to open and close the spiral or lever. Customize these tensions by crewing or unscrewing the connection with the proper fitting of the wrench. Made in France.
