There's a new SOG Seal Pup Elite without the serrations avaible now. I currently carry an older one wtih the serrations when hiking and like its size and light weight. I wish I had the smooth edge version however.

We used a Becker Crewman and an Ontario TAK while making the survival video and both held up well. The Becker is just a little too heavy duty for me carry on short hikes and I do not own a TAK, yet.

Doug's reccomendations would be good starting point as mentioned earlier.
