Real Keen was a knife brand manufactured by Robinson Cutlery -- the company which currently makes Oneida and a lot more. At least I'm fairly sure that Robinson was the parent.
This particular knife is a bread knife / slicer, NOT a bone saw -- although props to Phatch because the knife certainly looks aggressive.
Putting together a lot of things, my guess is that it was made either just before or after WWII. In other words, late 30s, late 40s, or early 50s.
If you really want to nail down the particulars, a phone call to Robinson to find the right person (if there is one), followed by an e-mail with a picture is probably your best bet.
