j_sepf welcome to the forum.
I am sure codger 64 will be along shortly and give you the complete history of your new found treasure. If you were expecting a buried treasure worth hundreds of dollars you will be disappointed. What you have a a great user knife made for Sears by Schrade Walden, probably prior to 1973. Codger will know for sure. This is known as a contract knife. Schrade Walden changed its name to Schrade in 1973. Last year after 100 years they went out of business.
What you have is a good user knife, good steel and a piece of cutlery history. Enjoy your new treasure and welcome to the forum.
