Dave, welcome to Bladeforums!
What you've got is not the most elegant set of kitchen knives in the world, but since Flint U.S.A. Vanadium is what we had when I was growing up, you should find they cut well and hold their edge.
They're probably even older, but I know we had them in the 50s.
You may have a problem restoring that edge, but it can be done with the right equipment and technique, and I wish my parents had done it, instead of getting rid of them. (growl)
