For anyone wondering what their "High Carbon" steel is, it seems to be 440c based on some scattered listings I could find. And while it isn't VG-10 like the other ones, I got 4 knives in 440c for 60 bucks, which I consider a steal.
For the less metallurgically inclined, 440c, unlike some of its 400-series counterparts, is pretty good. It was high-end steel back in its day. It'll run a bit softer than the high-end steels tend to nowadays, but should serve you well enough in food prep.
