My advice, for what its worth, is this. Pick up a couple of Schrade 8OT or 34OT stockmen off ebay. The 2 knives should only set you back about 60$ or so if you buy new ones. You'll have one to carry and a backup.
If thats not what you want, I'd go with a Case CV stockman.
Don't overlook knives by Boker or Bulldog, good stuff in carbon steel. Can usually be had in some nice scale materials that you can't get from Case.
