The history of knife, spoon, and fork is pretty interesting, actually, and subject to a wide array of opinion as to how it all evolved.
Common thought is that it was the knife first, of course, as an implement of hunting, cutting, and preparing food for meals so used it, too, to get food from fire to mouth. Spoons were common too, before the fork, as implements of stirring and mixing. Then evolved a forked stick or implement to better secure transport to mouth; then refined and only rich folks had proper 'forks' while common folk made do with whatever; usually spoons.
First forks were two-tined, it's thought, as used to help secure meat for cutting, then used too for shoveling bits to mouth.
