Bob’s Holy Grail…

After asking what is your corkscrew holy grail, Bob G. emailed in with is, explaining:

“My Holy Grail Corkscrew is the Philos Blake patent no. 27,665 of March 27, 1860. While it may or may not be the “first patent for a corkscrew “ it is certainly my number 1.”

Thanks Bob!
Other than a Briard (French Sheep Dog) named Philos Blake, we don’t have a Blake in the collection either.
Who else wants to chime in.  What is that ONE corkscrew that you would love to add to your collection?
