Group,
First, thanks so much for the warm welcome.
On Eric's suggestion i did a google search with the key words he suggested and imediatly came to a picture of my knife but from a different maker. That led me to a bit of reasearch about Sheffield's importance to knife making.
Pardon if im the only one who didn't know this but craftsmen in Sheffield has been a leading maker of knives, swords, blades, etc since the 1400's.
What i cant find is a historical reference to J. Clarke & sons specifically. Does anyone know if the british army/navy commissioned the same design to be built by different makers? That actually seems to make sense to me.
Im a bit blown away by the age of the knife because i had always thought he must have gotten it when he served in the U.S. Army in Europe during WWII. Wrong assumption on my part that the knife was made during that same time.
Thanks again to all who replied!
Also, i have a number of old knives i inherited from my grandfather (I'm 65). My Grandfather was a rigger in the merchant marine on the last of the "steam assisted" sailing ships around the turn of the century (1900) and i inherited his knives as well. I intend to share some of them with all of you as time allows but first i have to figure out where i stashed them!
