At first sight this looks like it might be a standard early Twentieth Century pocket corkscrew. However, it's much more. Once opened it reveals not only a corkscrew but also a screwdriver, an awl and a gimlet (the tool, not the cocktail !!!)
What a gift for the man in your life! Or even for the girl who likes a gadget and has occasional work to do around her home.
I have left this uncleaned, because the kind of man who likes this kind of thing likes to clean and take care of his own tools. However, if you intend it as a gift I can clean it to the point of looking gift-worthy.
