that's a chinese steel, right? similar to 440C, IIRC.
Less carbon and less alloying than 440C. More like 440A. There's nothing "confusing" or "disingenuous" about calling it a "high carbon steel", it's a fact. It just also happens to have a bunch of chrome in it... hence, high-carbon stainless.
It is. The site says it's 8Cr13 High Carbon Stainless Steel. WTF is that? Never heard of high carbon stainless.
Sure you have, you just didn't realize it

With rare exceptions, every good knife steel is medium or high carbon. It's the carbon level that makes steel hardenable. Whether or not it's stainless is irrelevant.
8Cr13MoV is a mid-grade stainless cutlery steel with .8% carbon, 13% chromium and a splash of molybdenum and vanadium (less than .3% each). The carbon allows it to be hardened, the chrome helps with quenching process, forms carbides and provides corrosion-resistance, and the Mo and V are there to keep grain structure under control and help it harden through without severe quenching. There's nothing real spectacular about it, but it makes serviceable knife blades and doesn't cost a whole lot. I'd put it in the same class with AUS-8, 440A/B, 420HC, etc.
"Super" stainless steels like CPM-154, Elmax and so on have
even more carbon than plain "high-carbon" steels like 1095 and O1, and boatloads of fun stuff like moly, tungsten and vanadium. They need the extra carbon to form carbides with those elements; the carbides are what gives them more abrasion resistance.
On the other hand, there are also many grades of low-carbon stainless, that can't be hardened but is pretty tough and extremely corrosion-resistant... used for knife guards and Corby bolts and doorknobs and toasters and all kinds of stuff. Look around, your house is loaded with it.
Sorry to geek out on ya like that... don't start me to talkin', I'll tell everything I know.
