Rc of Queen D2

[beckerhead]

Anyone know the avg. hardness of the Queen D2 blades? I am considering a Country Cousin (AKA Sodbuster), and was curious.

It's definately on the soft side for D2 something like 57 or 58.

Just hung up with Queen customer service, they indicate 58-59. I have plenty of blades around that range that I really like, but no D2 blades whatsoever.

I suppose this is why so many people complain about how tough they are to sharpen?

D2 has very large carbides, it'll be wear resistant even when soft. Same went for S60V/440V, it had to be left at around 56-57 because it chipped easily, but new grinding wheels had to be made to manufacture the knives. If the steel ends up developing large burrs from a soft matrix, and has really wear resistant carbides in that matrix, it's a one-two punch to sharpening attempts.
