I've enjoyed compiling this corkscrew guide, I hope it can be of assistance to you. If you'd like to get in touch it would be great to hear from you. Peter@corkscrewsonline.com
In 1876 Edwin Wolverson registered a design which added a hole in the shank. This was for the middle finger when grasping the corkscrew.
Expect to pay £35.00 upwards for this sought after corkscrew.
