I would carry the BK9 so I could always say, "That's not a knife, [pull Bk9 smile and say] now that's a knife."
I'm sure it was designed for countless tasks. I feel that if I give my explanation, it would be a futile act. I'm not going to change anybody's mind on how to use the Bk9. I'll only have to argue my usage for it, again and again "till I'm blue in the face".
Use the BK9 for what ever you want to use it for. Fillet it and fish fry it, it's your blade, do what you like. Beckers are fairly low in cost and are hard working tools, so have at it.

if you would like, i (we) can have the designer/maker/etc of the BK9 TELL YOU in his own words, what it was designed for
i will assume, in advance, it will include tool, knife, hard use, chopping, etc.
cuz really, while your opinion is valuable, we can just cut to the chase on this one, the final word, end of discussion, done
which would also include "use it hard, put it up wet, if you break it within normal designated usage that is not deemed abuse, we will cover your assets"
or something like that. great warranty.
and we'll note, that KaBar has sometimes, and Ethan has MANY times, covered a warranty issue, on a CAMILLUS product. now. seriously. what more do you need to hear?
