If I'm reading this correctly, you're willing to spend more if it can pull double duty, but otherwise you're looking for a dedicated kitchen knife right?
If so, I stand by my statement. So far the Tojiro DP seems like the best fit to your request from a "soley kitchen knife" perspective. Also, it seems to run about $30-40, so it should be well under budget.

If you're looking for a hybrid camp/kitchen knife in that size... that does get a bit harder. The old hickory suggestions are good, but they'll take a bit of work to clean up. I wouldn't suggest a Mora for food prep at all (scandi grind doesn't work well for food prep, particularly thick/tough things like carrots or potatoes. You end up "batoning" through them when they get thicker. Mora DOES make a FFG blade, which might work for you though (Craftline Flex).

You might be able to scrounge up a AG Russell Deer hunter on the used market, which is close to your requirements. Its got a .06 (iirc) thick spine, FFG, but its a mite short in the blade (4in).
Top blade. Its discontinued, so might be harder to find.
So, personally, I'd go with a dedicated kitchen knife, and spend the remainder of the budget on a knife you want for outdoors. Kitchen knives are specialized for a reason (they usually have space for your hands when used on a cutting board for starters). I think getting a true hybrid of both kitchen/outdoors would leave you somewhat disappointed in the long run.
Good luck finding something that works for you
