Just got my 43 and 47A, neither are numbered, but no big deal to me. The first impression I got from the knives was the robustness of the blade spines. The grinds on the Colver Bowie and Tanto retain almost full thickness of the spine almost to the tip. Much more massive blades than the Weehawk on the 42. The drop point tanto has the same profile as the Elishewitz custom tantos. Pretty cool. Lots of blade mass. Like it.
I really like the Colver bowie blade a lot. Very unique in a production knife.
Very nifty profile to the choil kicks on the new blades, looks classy. I notice metal bushings, can't remember seeing metal bushings in the 42s I have. Tang pin looks larger diameter too, but that might be poor recollection on my part.
