Wenger Swiss Army Knife, 'Traveler' or EVO S14 models, or the 'Handyman' model if a saw and philips screwdriver are more useful to you than a corkscrew, all of which can be found on ebay for <$30 each. If you'd prefer a different selection of tools or a serrated edge or a locking mechanism, those options ARE available, just peruse the web until you find a model you like, then search your preferred knife-purveyor for that model.
I consider Wenger superior to Victorinox SAKs based on blade, scissors, and can-openner design.
These are simple, classic, multifuctional, people-friendly tools - you'll be amazed at how often you find yourself using one, and the different tasks you can accomplish with the varied accessories.
Paired with a good hatchet, you've got an excellent camp set.
