Jim Crax corkscrew

I should have posted this in August when I received the Jim Crax corkscrew in a private sale. This is the Walter Ruby designed and manufactured pencil corkscrew. I also have hopes of acquiring a copy of the Knud Knudsen version of the device, but for now I am happy to have this family artifact. I am not a great photographer but here is my attempt to show it off in its environment.
