Today I received the chisels and the quality is good, certainly well above that of lets say a Stanley Fatmax chisel. The chisels are fairly heavy but that's a result of the tang going all the way through the handle. The backs on both chisels have a slight hollow in the middle but it doesn't extend to the edges (like a Japanese chisel but the hollow is a bit smaller). That's exactly the way I like it because it speeds up sharpening and I'll only be using them for flushing operations anyway. As for the steel, there's no documentation on what it used. Going by how it sharpens and the edge it takes I'd say it's a high carbon steel around 60HRC.
