SAK Electrician for me but I agree. I get a lot more done with a SAK than any single bladed knife I've owned. If I'm carrying a modern folder it's in ADDITION to the SAK.
I took the OP's meaning to be single blade folders, I guess just because that's mostly the sections of this forum I spend time at.
But my truest EDC would also be a SAK suppose, and it does indeed get used every day, in fact if something were to happen to it I would most assuredly replace it within 24 hours:
