As Steve (knifeaholic) previously stated, the OP’s knife was manufactured no earlier tnan the late 1970s and the blades are stainless steel. Kabar introduced a line of wood-handled, brass-bolstered, stainless-bladed traditional pocket knives in approximately 1977. These knives were not produced for the Kabar Collectors Club; instead, they were a regular production item. The tang stamp on the OPs knife is consistent with this 1970s product line. After forty-odd years I can’t recall what these knives were called; I believe it was something like the “classic” series.
At the time this knife was made, I was living in Olean, New York (the home of Kabar) and was an early member of the Kabar Collectors Club. As part of the club’s membership benefits, I regularly received catalog inserts as new products were introduced by Kabar. Forty years and many thousands of miles later, I have somehow managed to retain most of this literature. I know that I have the catalog insert for this series of knives; I saw it just a few months ago while researching a Kabar jackknife that I had purchased. Unfortunately, I am not currently at the house where these catalogs are stored and am unable to post a photo of this catalog page.
