Bushcrafter (boy, I've got a lot to say!)
I think many people on this thread are just avoiding the question. The issue is what knife you would rather have in a survival situation, and not, how likely do you think it is that you will be in a survival situation. An answer along the lines of "I will never be in a situation where I would need a survival knife, so I only have a bushcraft knife with me", is not a response to "what knife would you rather have in a survival situation". Similarly, an answer such as "I only need a bushcraft knife because I always have an axe with me" does not answer the question.
Maybe your question is silly? Maybe others use it as a springboard for disussing things they feel is of more interest? Maybe the answer is there all the time, but you are unable to see it?
I would carry a "bushy" blade (Mora, SKB) because that would allow me to carry out just about any tasks that is within the reach of a knife in a survival situation. But I will also insist that the question is silly, since there is no difference between buschcraft and survival once you reach a certain skill level. Let me illustrate by taking an example.
Think of two persons. One is Mors Kochnski (or RM, Lofty, Lars Fält, etc) and the other a random chav who has never been outside greater London (M25?). Dump them in a northern Swedish forest with only a knife (of their choice) in early June, around 8 PM, in a light drizzle. For the experts it would be no big deal, just a matter of building a shelter, making a fire, and then start finding their way out the next day. For our stereotypical chav it would be a major survival challenge, and no knife would make much of a difference. But it is the same situation! Once you have the skills it ceases to be a survival situation and becomes a matter of bushcraft.
We have a bit of that problem in the Survival Guild. A couple of decades ago the "challenge/hardship" courses were 5 days, with only a knife and a firesteel (or a few matches, plus some extra clothes). Today the equivalent is 10 days, with no knife or firemaking tools ("just clothes"). The reason? The number of people for whom 5 days with a knife and a firemaking apparatus would be a pretty relaxing "walk in the woods" have increased. Without adding silly things (military SERE stuff, faked injuries, doing it naked, walking inordinate distances, taking a kindergarten group along, etc) one soon is at a point where it is difficult to make it more challenging and still keep it compatible with normal peoples lives (i.e. no month long courses, no kidnapping people from their places of work). I suppose we should run it in mid October instead (we already do a winter version, and there one runs into safety limits pretty quickly).
