I recommend any one of the following:
Buck 119, Punk, Thug or Hoodlum
Cold Steel Leatherneck SF (new 2013 model), Survival Edge, Master Hunter, Recon Scout, Trailmaster, Gurkha Kukri or Bushman
ESEE 3, 4, or 6 (5 is also good if you expect to run into some really serious business)
Becker BK7, BK9
Busse Team Gemini Light Brigade
Mora Companion Clipper
What would I not recommend? I'm only mentioning it because it has been recommended in this thread, and that is the Benchmade CSK II, which has been shown on video to chip heavily during light use that I should be able to trust a decent medium to large-size folder to take care of:

On that note, please don't baton with your knife. I don't care if it's a Cold Steel Trailmaster or a Busse or something, unless done with perfect technique, you can cause serious unseen damage to your knife which can and will end in eventual breakage. I've seen it happen on top-shelf survival knives like the ones I just mentioned. Bring a saw, machete and/or an axe. There are lightweight and effective options and alternatives like the Sawvivor and Special Forces Shovel which are so awesome that there is no excuse not to have them or something like them.
