Does it have to be folding?
Many high end brands made-in-america have economy models, but quite often the economy models are contracted out and made in china. That's why you can get a Kershaw for thirty bucks. If you want something easy to sharpen, or sharpen friendly, go with 1095 carbon steel. Mora Knives, made in Sweden is the best bang for the buck at 15 bucks and less, more if you want something special,...but they are fixed blade. They come in 1095 and stainless. It is not easy finding high carbon steel folding blades. If you find one, please let me know.
Why do you need serrated. Most cutting chores are done on the blade right by the handle, serrated gets in the way.
Otherwise, Buck made-in-america is a knife that is dependable.
Kershaw Skyline gets a lot of respect.
