If having a custom fixed blade knife made, here's what I'd ask for: Drop point blade. 10-12" overall with a 5" handle. Flat or convex grind. Natural handle materials, probably wood. Full tang. Guard.
You didn't say what kind of hunting you do, but for small game I'd want something like the AG Russell Woodswalker. I've never been big-game hunting, but would probably look for something like the Bark River Classic Light Hunter.

I wanted to comment on this also:
No, I DO want to lug around a big knife, we have lots and lots of 600+ pound black bears that have no problem getting within 10 yards of you and not spooking. We can't legally carry anything here, no guns, nothing.
Where do you live? Are they North American Black Bears like we have in New Mexico and Colorado? If so they are mostly harmless and can easily be scared off with loud noises. In the entire written history of New Mexico, exactly one person has been killed by a black bear.
I'm not saying you don't need to take precautions, you do. But having to fight off a black bear with a knife, and being successful at it, is so incredibly unlikely, it's comic book material.
Can you carry bear spray legally? Someone down in the Wilderness Survival section just asked about those types of products. I've never used anything like that, but it doesn't sound unreasonable as a precaution.
