A year ago I was given a kitchen knife in VG-10. I like it in many ways, but it's a bear to hone. The alloy supposedly has great edge retention, but in my opinion the edge that "keeps" is a semi-sharp one. Therefore I'm sharpening so often anyways that I'm thinking I don't really have any use of this alloy and its hardness. And it's wearing on my hones. It's written 60hrc on the side of the blade. Would I be doing a silly thing if I took it back to, say, 58hrc? Tempering charts for this alloy seems to be kept secret, what temperature would give 58?
