I will say that my path I expect was fairly typical on the survival/bushcraft thing. I always carried folders. Even camping I seldom had a fixed blade with me for years. I would often have an axe with me car camping which is the dominant form of camping that I do.
Being younger, my first custom knife was geared toward hunting applications which I routinely did. Then the survival thing kicked in and I chose a number of blades but they all had 1/4" blade stock and tended toward the a fighting knife bowie type design (think Randall, EK). But my most loved Randall was in fact a more normal blade (Jack Crider Special). Things stopped there for the most part until I joined BF. I started with the heavy 1/4" blades like the BK-2 and ESEE.... then moved toward a middle blade stock thickness for most everything I am likely to do with a knife. I have choppers, but I seldom need to chop anything other than machete work. I am in a machete phase now and like both the heavier and lighter machetes for many woods applications along with a folder and a middle sized fixed blade. But you can see where the influence came from.... survival meant fighting or possible fighting with a knife and woods activities leaned toward middle sized blades.
There is obviously urban versus rural choices and cutting applications in a survival event. Rural would probably lean more toward bushcrafting and urban more toward larger heavier knives for prying and fighting. But I am no knife fighter, so that is a fantasy.
I have a similar background, and "path" to you it would seem.
I started with a BK2, and while I still have it, I don't use it all that much. It is a great knife, and will be something I will value when I need something like that, the reality is that I'd rather carry two knives that are more specialized instead of just the BK2. I seldom chop with anything (folding saws are many times more useful for the location I am in and the amount of wood I need for an evening campfire). So my "Nessmuk trio" is a folding saw, a larger blade, and a smaller one.
And I may be in the minority, but I don't really think about "urban survival" all that much. When I think about that type of stuff, I'm usually at/around my apt, so I would have access to all of my tools, so I worry less about an "urban survival" knife. And like you, I have 0 knife fighting skills, so that doesn't matter much to me either.
BK2, BK7 survival knives that can be used for bushcraft IMHO
BK16 and BK12 Bushcraft knives that can be used for survival....IMHO
Thicker bladed overbuilt sharpened prybar type knives with full tangs tend to evoke thoughts of survival knives to me....
Thinner, lighter bladed knives with a tendency to overvalue ergonomics evoke thoughts of bushcraft knives to me.....
but as always, my opinions are worthless to anyone but myself and I fully expect to be found in the minority of folks once the dust settles....
The big callout here is that I think that individuals comfort level with the tool cannot be understated. People used to using larger knives for things are quite proficient with them, while others are used to using, and are better with smaller blades. Another big differentiator is location, as different tools work much better in different locations. This to me mostly means that every knife owner should practice the things they think is likely that they will need to do with the tool BEFORE they need to do it. That way you learn now to use it most effectively. And while i'm no expert (particularly compared to many here), but I feel just about as comfortable performing most basic tasks with my BK9 as I do with my Mora, it just takes different approaches to solve the same problem.
What you've said is absolutely true, that a "survival knife" can be used for bushcraft, and the reverse is true as well. The difference is that one may be more suited to the tasks needed than the other.
One thing I question though... is it possible to "overvalue" ergonomics? Myself, its a big factor in blade choice, as when you use the tool for a few hours, you notice any problems with them. So from that point of view it seems hard to overvalue it, but I'm open to being wrong
