Then you become obsessed with weight. Long distance backpackers frequently go for the Victorinox Classic. Heavier knives get sent home or given away.
Remember that most of the time on long hikes, you're
carrying your gear, not using it. Also just like at home, 1/3 of the time you're sleeping, so your sleeping bag and shelter are the most important then. If you check out some of the equipment lists from people hiking the 2663 mile Pacific Crest Trail here:
http://postholer.com/journal/sampleGearlists.php you will see what a low priority cutlery takes on a trip of that length.
An inexpensive knife and an 800 fill down sleeping bag is a much better use of your money than an expensive survival knife and a Walmart sleeping bag.
Also get comfortable shoes and a good quality pack that fits, or those two items will torture you all day.
I would rather have a slightly larger folder than a Vic Classic for around two ounces, but YMMV. If you want a fixed blade, it's hard to find anything that can beat the cost/weight/utility of a Mora. :thumbup:
