If you spend more than a week anywhere without a proper hatchet, saw, or machete you are underprepared. I wouldn't want to build a shelter with a Mora, but I could. If you can carry a 7" beast of a knife on your side, you can carry a small hatchet and a knife 5" or less and be better prepared for a wider variety of situations. My day trip knife is a Victorinox Huntsman and I never feel under knifed. Oversized "survival" blades are cool but highly impractical for anything but chopping. They are just too long, and too thick. Take a small hatchet. I feel like a "one tool option" is a seperate topic and the only good arguement I've ever seen for one is Andy Tran talking about his camera equipment being too heavy and bulky for him to want to carry a hatchet and a knife. Your mileage may vary.
