I see no reason why I'd want a D2 knife for bushcraft. Edge holding is not an issue, particularly after cutting over a kilometer of cardboard with a $7 stainless knife from the local grocery with a blade made from unknown stainless, and still being able to make fine curly slices in notebook paper and cut a folded piece of notebook paper while it sits on a table edge. If corrosion resistance is a concern, a real stainless will take care of that. 1095 all the way. Expanding selection, 1095, 1080, 1075, 1055, 1095CrV, 8670M, O1, 12c27 and (M) version, A2, 440A, and many similar steels would be my choice. Heck, a repurposed old machete blade would be great.
