Do you know much about his life, like what he did and where he lived for most of it?
When I see knives like these, it always makes me think of when I was growing up. It was a different era then, and almost every man who had pants on, had a pocketknife in there someplace. Most times it was a small two bladed pen or jack. Nobody ever seemed to carry a large knife, but my memory is filled with the typical "old guy with a little pen knife" kind of scenario. It didn't really seem to matter if it was a true pen or a small hack, they were always referred to as a "pen knife" by most people. Kind of like in the 1970's any large single bladed knife was sometimes called a Buck knife.
I think it makes a statement of some kind how these men managed to get by very nicely with a small pocket knife for their everyday cutting needs. Now, if only those old knives could talk!
