Steel Spring Corkscrew
Patented by Sir Thomason in 1802, the double-action system enables you to pull out the cork easily by continuously turning the handle in the same direction.
The aim is to reduce the physical effort required to remove a cork and so allow you to open the bottle gently.
The first helical shaft causes the worm to penetrate the cork.
When it reaches the bottom of the cork, the larger helical shaft turns in order to pull out the cork.
A ring of leather placed at the base of the corkscrew protects the neck of the bottle and adapts the device to different bottlenecks
