I respectively disagree Sunnyd and I understand the difference between 420 and 420HC. This URL gives a comprehensive table comparison versus other steels:
http://www.cutleryscience.com/reviews/blade_materials.html
In composition, 420HC is closest to INOX, the steel used to manufacture many Swiss army knives. I find Swiss army knives to be very usable tools (I own 5 Vics?) but I wouldn't compare my Swiss army knife blades to knives with blades of any of the steels you listed.
I'm sorry if you take offense to the words "low end", I certainly did not mean to imply it was either a poor value or a bad choice. Perhaps I should have said "lower end" as in not the worst choice. Certainly it is not "low end" relative to the many Taiwanese imports made of "surgical steel", whatever that is
. It is simply a lower priced, lower performance steel in comparison with other modern stainless knife steels like VG-10 and S30V.
The URL you referenced in post #2 is Buck authored marketing material and I greatly prefer manufacturer independent sources when they are available.
I snipped this quote this from the Knife Steel FAQ:
"440Aand its relative peers, 425M, 420HC, 12C27, and 6Aare the next group. They can be hardened more than the previous group, for better strength, and they are more wear resistant, though wear resistance is just getting to the point of acceptability. 440A and 12C27 are the leaders of this group, with solid heat treat both perform okay. 12C27 is said to be particularly pure and can perform very well when heat treated properly. 6A trails those two steels, though with its vanadium content, can take a razor edge. 425M and 420HC trail the rest." The URL (which contains much informative material on knife steel) is
http://www.zknives.com/knives/articles/knifesteelfaq.shtml and the author is Joe Talmadge.
Please do not assume I am uneducated on a topic simply because you disagree with my statement. Oftentimes relative comparisons are interpreted very differently by each reader. Only through continued discourse can we discover the author's meaning and assumptions.
Finally, as one who also values education and correctness I should point out that D2 is generally not classified a stainless steel even though D2 steel is very stain resistant. D2's chromium content is just slightly below the threshold many consider "stainless". Regardless, it makes great knife blades. This is why I suggested that I would rather choose the Queen knife in D2 over the Buck Woodsman in 420HC.
