I'm in the Ron Hood school of thought on SAKs.
Wenger or Victorinox, Big blade, locking blade, saw. He calls the SAK as your "primary knife."
I have a Rucksack that sits on a shelf. I replaced it with a one handed Trekker. It has a phillips head screwdriver which allows me to carry the smaller Mini-Leatherman that is without this screwdriver.
