Fork and... spoon? What crazy world is this?
I use a knife and fork for most main meals, unless it's something like ribs or other meat that's on bone, in which case I use my hands. If it's something like steak or chicken breast, I'll usually cut it and then just stab it with the knife in order to transport it from the plate to my mouth. Sometimes chopsticks when I'm eating asian food.
Can't say I've ever really used a spoon for eating something other than ice cream, although I've never been a big fan of soup.
