Amen, used to be that you could buy some cheap junk carving chisels for a couple bucks at the discount stores. I don't think they even used carbon steel.
A good set is gonna be pricey, no matter. And there are the large Totoem Pole carving tools, the medium furniture carving tools, the even smaller cuckoo clock type carving tools and then the fine ones suitable for incising long rifles.
There was a wood carving shop when I last visited Dollywood in TN. I watched in amazement at the ease with which the carver worked, even with giant chisels and gouges and in oak no less. It was a sight to behold. And then I asked about th tools. He claimed the gouge he was using, maybe 2 inches across, was itself over $200. Some thing about Sweden or some Scandinavian country.
Quite a surprise, but with what I saw him doing and the ease of it, well worth it.
I have a carving set that came from Austria. It was given to me when I was around 12, by an elderly friend of the family with the story that it had been his when he was my age and his uncle's before that. They are good, but hard to keep a good edge on. I use a fine ouachita stone that came with the set.
