Out of the box without any mods there is a fair chance the Dozier will have a bit thinner ground edge. That alone will cause a different level of performance skinning or cutting through hair, skin and muscle. The D2 has a larger grain structure and has often been used in skinning and hunting type knives because of this. 3V can, however, do anything D2 will and more. I have a different Dozier and the Koster Bushmaster. I consider the Koster tougher and better for all around stuff, including pretty heavy use. The Dozier is likely better suited to the pure skinning/flesh cutting role though it is no weakling.
I like and have both. I don't consider them the same category knife though they are both certainly premium, well built knives.
If I was going to specialize on skinning/hunting I'd thin out the Bushmaster some but feel certain it would handle anything I need it for. I wouldn't feel the same about the Dozier and using it for wood cutting, mild batoning type jobs that the Koster won't notice.
