Been a long time since I posted here...
I recently received a really nice knife that has become a constant companion. It belonged to my uncle Mel's father, Mel Sr. He passed away several months ago, having nearly reached Centenarian status.
His knife is an old Robeson, stamped:
ROBESON
SHUREDGE
USA
...which puts it in the 1940 - 1964 range.
It's a 2-blade jack, with black jigged delrin(?) handles.
Both blades have been sharpened so much that they're ghosts of their formal shapes.

The secondary blade (used to be a pen, I imagine, while the master was once a clip) is so thin that it's needle-sharp at the tip, and probably only a centimeter wide!!!
In any case, Mel Sr. was an amazing guy. For example, at the age of 88, following the passing of his wife, he was dating 3 women and driving a brand new red sports car.

An inspiration to us all.
He was a practical man, one who didn't waste a thing, and always enjoyed working with his hands. His knife speaks volumes about his life, in my opinion.
