As a long-time carpenter, I find a two-knife carry useful--one that's a really sharp, really good cutter/parer/slicer/carver and another that's a beater. My work edc is a CF Sebenza along with a Tenacious or RAT, both of the latter with combo-edge. The issue with the beaters is poor edge retention.
If I had to go with just one blade I think a Spyderco Manix, either regular or LW would make a good choice. The regular with S30V steel would give good edge retention. A Benchmade Griptilian would also be good in that role. The Pardue version in 154CM is good steel, holds an edge OK, and is at the lower end of your price range. A Doug Ritter Griptlian from KnifeWorks has a broad, strong blade of M390 and would be a helluva choice and a great gift at your upper end.
