The 'one knife thing' comes from people who do not have the financial resources to buy more than one knife and need to make an informed decision. It comes from real world situations where people make do with one knife. I've used the USAF myself, starting in Arctic Survival School. Extreme sub zero temps, a well used knife, unseen production flaw and a young enlisted man all contributed to it snapping from the 5th saw gullet diagonally down to the edge. I saw several tips snapped off too, a inherent design weakness. We had only one knife, because we were only allowed one knife. My instructor issued me a second knife. Even as a dumb 20 y/o I figured if this happened in the real world there wouldn't be instructors around to hand out replacements. Again, I've used this knife, and knowing it's particular drawbacks, and every knife out there has a few, like it for what it is and can do. If you reread my reply, I am using different examples for each possible task to show their pros and cons.
