Welcome to KF
Edge was a mark used by US importer Gutmann Cutlery from the 1950s to, at least, the 1980s.
Collector value is, probably, low...$40-$50 at a guess. They were made in huge numbers.
The design of yours is fairly "generic" for the time...many German companies produced knives with similar construction.
I have no idea who made the Edge knives, though.
There were various blade shapes.
BTW, despite the low value, they were, mostly, good user knives.
Not knowing the answer is not dumb. Providing an answer, anyway, is dumb.
