After digging a little deeper, I ran across a George L. Hart, who has several of his patents for cutlery assigned to our man James D. Frary.
And, after even a little more digging, I found that George L. Hart was awarded a patent for his metal rolling machine–which would allow him to make….
No, not corkscrews, but knife blades and other flat ware…
could this be the patent for Hart’s Patent ALL Steel Cork Screw???
I will continue the hunt.
