Yes, they are. I once heard from a friend that they had used a kuni tied to a rope to hunt. Considering all I know about this friend, I wouldn’t put it past him. What’s more, why stop making a weapon that works?
Oh, yes, both real and ancient. What they aren’t, exactly, is a knife. The kunai is a tool of ancient origin. It looks sorta like the kunai knives you see in manga, but the blade is a lot thicker than a knife. In fact, toward the hilt end the “blade” is more or less square in cross section; almost as thick as it is wide. It’s original use was as a tool for agriculture— it would make a nice hole for planting— and for stonemasons, who used it as a pointing tool, a (small) pry bar, a miniature trowel and a pick. Basically, it’s a short piece of steel, thick enough to pry with, and a moderate point. It’s useful for all sorts of things, kind of like a pry bar is about the handiest tool in anybody’s box. And, naturally, a martial arts master can turn that into a weapon. They were also used by the “ninja”— who also aren’t exactly as depicted in popular culture— as a sort of loose piton to scale masonry walls; a “handle” you can wedge into a crack and haul yourself up on. Now, there’s no reason you can’t make a knife shaped sort of like a kunai, but thinner. Toward the hilt the blade would be diamond shaped rather than squareish, a lot wider than thick. This would give them an acute enough edge to be worth sharpening and make it work like a knife. It would also have a very thick and stable spine for the blade and would make a great dagger and an even better throwing spike, if not the all time world’s greatest slashing weapon. In fact, many custom knife makers are building kunai in this pattern, doubtless inspired by the usage in manga, and also doubtless because people line up to buy them. It’s not a knife I would pick, even for fighting. The problem with a kunai knife is the same as the rapier. It’s all point and no edge. Yes, the point is mightier than the edge, but it’s nice to have both. If I wanted a dagger, I’d prefer something like a Fairbairn Sykes; it’s longer to reach deeper and has a better handle. If I wanted a bigger weapon and wasn’t worried about concealing it, a modern copy of the old Roman Gladius/Greek Xiphos has never been beaten for a short sword; they’re not much longer than a Bowie knife and a lot deadlier. If I wanted a throwing knife, I’d want it thinner and with a leaf-shaped blade for a better cut in case of a glancing hit. But yes, they do indeed exist.

Yes but they weren’t knives, as such. They were primarily digging and prying tools, used by the ninja. They could of course, also be used in combat
