I have half a dozen Queen knives in D2, but none in Zebra wood.
The fit and finish of all of my Queen knives varies from good to exceptional.
The D2 holds an edge very very well. Most of my Queen knives have had very oblique edges when the came from the factory. By my estimates the per side angle is ~25°. I use a DMT extra coarse stone to change the edge angles down to 15° per side. Once there, they cut well and hold an edge well. Using a diamond stone it takes a while, if only because you are removing a fair amount of steel. Using a Sharpmaker. it takes a long time. Using a natural stone like a Washita, it might take till the next millennium.
