Silly Q but do you mean a hand fork! Or a fork that's as big as a spade!
Just to confuse things more, I have a hand fork which looks like a little rake and to confuse things further still, use it turned upside down, like a hoe, in raised beds, where plants are planted far to close together to use a big stand up hoe, to weed effectively.
Bought it from Aldi and wouldn't be without it...they sell a few other hand tools, some of which whose uses aren't that obvious, might be worth a look.
