I have both the S&W SWAT with G-10 scales and a CRKT M-16.  I like these very much and rate them better wilderness knives than my Spyderco Endura.   I paid about $35 for each of them.
The CRKT M-16 is very easy to open with one hand.  I got it with the half serrated blade and wish I had opted for the plain edge.  The serrations are very sharp but I think they detract from the blades usefulness in the field.  I carry it more in the city, but I have used it for food prep and cleaning small game in the field and it did very well.
The S&W SWAT makes a very good wilderness folder in my opinion.  It is a very useful and strong knife.    I carry this one most often if I'm hiking in the higher elevations where there is less to cut and I can get away with a light folder.  
I agree with whoever rejected concave edges for the same reason.  They cut well when sharp but are very difficult to sharpen again.   I would suggest a plain edge that is easily sharpened on a flat stone.  Mac
