I'm not simply repeating what I've heard, it's based on personal experience. Here's a picture (photobucket has changed drastically, hope this works) of a Queen 4180 in D2. I thinned the edge out, and look what happened. I have always had great experience with Queen's D2, this one is at 10 deg (or so) inclusive. Once I put a microbevel on it, no more chipping doing the exact same task.Why? I mean...D2 is used in Industrial Scissors and, in my experience, D2 at a maximum hrc of 58/59, is a real good old steel.
I mean...It will not chip easily, not even with a real thin edge. It will NOT takes an real scary laser edge, but it will keep it a for a nice time, and you can shave easily anyway.
It's, to me, an "often found" wrong attitude with this steel. Maybe 'cause of unproper HT of the past makers. Infact, i don't believe that 60 or more hc are good for D2. You must stays under 60, and with the right treatment it wil have better response in every single aspect, included stain and rust resistance.

Yes, D2 used in industrial applications for cutting metal (so I've heard), but it won't have the side load that a knife experiences, and I'm sure that an industrial edge is much thicker than a knife. I find it amusing when I hear people say that D2 won't take a great edge. I find it takes a screaming edge, and holds it very well. It might not be up there with S90V, but it's nothing to sneeze at.
