I wasn't ever talking about carrying only 1 knife. I was comparing a good solid knife like busse kin to a cheaper weaker knife and backup of the same blade. I always have 2 folders(different of course) so it wouldn't hurt me any with a 7"-10" blade. If I did have to go out with only 1 knife I'd want something like a BATAC or SJTAC.

I guess there is a point where you reach "good enough" though. I have at least a dozen folders I think are good enough to carry, when I could have easily gotten a few customs for the combined price. So I guess I halfway agree in that regard. And I definitely agree with a few extra blades of different sizes.
