I share desertrat's opinion.

A Leatherman Wave, a fixed blade, and maybe a Gerber Sportsman's saw will cover all the cutting chores I have seen anyone do. Some like to use a hatchet to make kindling, I prefer to use a fixed blade. For low budget get a Mora fixed blade, about $10 from Ragnar. A Gerber Sportsman's saw is about $13.00. I also would not skimp on a multi-tool. The Wave is great! Get the pocket clip and use it as a one handed pocket knife.
