+1 to Savagelh. I would also add a hammer and a hatchet. Keep 'em in the trunk, just in case.
A coffeemaker's optional.
Something by Benchmade to round out your collection. Benchmades pass the $130 mark pretty fast, but the Griptilian is a good knife for the money and has a lot of choices for handle and blade materials, as well as blade shapes and coatings.
Buck makes a big folder, I think it's called the Alpha Bravo, which has a Besh Wedge blade. It's not a slicer in any way, but it's supposed to be able to handle some abuse.
