Lone Wolf makes a lot of knives that they put wood handles (of various kinds) on. They use quality materials, premium steel, and make them in Oregon.
A.G. Russell makes their One Hand Lock knife in desert ironwood and 154CM, all made in the USA (the ZDP-189 version's blade comes from Japan--nothing wrong with that though). Nice, but not cheap.

You can get Chris Reeve Sebenzas with wood inlays. Very expensive, but the best made production knives you can buy. Made in USA.
Benchmade makes the occasional knife or variant with wood. 440, 480, and 690 for example. These tend to be smaller, "gentleman's" knvies though. Premium materials, made in Oregon.
William Henry makes beautiful knives. But they're gents blades, and even the basic models are expensive. Probably not what you're looking for, but they fit your criteria. Oregon made (although often with Japanese steels).
As mentioned in previous posts, Buck makes a bunch of different models and clads them in wood. Made in USA.
Of all of these, your best bets would be a Lone Wolf or a Buck, unless you're looking to spend quite a bit of cash. They're more reasonably priced (none more than $150) and probably better suited to hunting/outdoor use than the others as well.
Hope this helps.
