I think he is talking more about the knife than the situation. Survival knife is indeed sort of overly broad term. I suspect, in general, today, survival knives tend to be full tang, synthetic-handled (micarta, G-10, FRN) knives more or less patterned after bushcraft knives and "theater knives" in terms of blade shape.
But of course there will be a hundred valid deviations from my attempt at a definition. It is kind of one of those things were, I think I'd know one if I saw one. ESEE knives - Check. Becker knives - Check. Falkniven F1, S1 - Check. Case Sodbuster - No. Queen Congress - No. But that leaves a lot of room in the middle there where it is any body's guess and if you were trapped on a desert island, or in the middle of the desert, you sure be glad you had a Queen Congress if that was all you had.
I suspect our OP means the former set of knives and their functional kin...which is why I give a wholehearted endorsement to the ESEE-6.
