A question that occurs to me is "Do you have a knife that you consider a survival knife? Something you would want to use when TSHTF?" And if so, how do you know this won't happen when you're backpacking? And if you can tell these things, then you can completely avoid them, therefore never needing anything bigger than an SAK. (and look at all the money you'd be saving

)
But what if you're wrong?
I don't backpack anymore, although I used to and I understand the weight considerations, but I would cut corners every other place, but not with my knife.
And I agree with Elen, that you can get by with a stone chip to fulfill your knife needs, but who wants to?
And as far as Moras are concerned, my experience with them, apparently, have been much more rewarding than Pitdog's. In fact, even though I used them for years, I never knew they were inadequate until I joined this forum.
So why did I buy an RC-3, order a Hairy Carry, express an interest in an Active Duty? Because I love them all!

but I can get by very nicely, with just a Mora.
