I don't think it is up to Bob Dozier's standards, but I always carry a Queen and I find the edgeholding to be very good. In direct cutting tests with cardboard and pine, it has proven to be equal to or slightly better than my Spyderco S30V Native for edgeholding, and just slightly behind my Benchmade D2 (Cabelas mini-Grip).
The one common issue with the Queen D2 blades is that they often come with very obtuse edges, so it takes some work to thin them out to where I like them.
