When I am having surgery, my life usually depends on the knife the surgeon is using!
What does that mean:"When my life depends on it"? How is my life supposed to depend on my knife? If I am threatened, I would prefer a big long stick or a hand gun and no knife at all. If my life depends on an operation someone is performing on me, I would like it to be one that is suited to the task.
However, if you are referring to a survival situation: Most survival situations I am fortunate enough to be able to enter them on my own terms (meaning, when I go hiking, I can select my gear). Since I am usually flying transcontinental a knife would not be of much use to me in the event of a plane crash...I would simply drown. If we have a Y2K like crash of all infra structure, it will still take a while to take effect. Plenty of time to choose my gear from the stuff I have at home. Since I can select my own gear I would always TWO knives, one big, one small (around 3" and 7+"). And if we are saying, simply for the sake of the argument, that I am allowed only one, I would take one of medium length (5-6"), that does each task equally poorly....
