I've got several Bark River and Dozier, very different grinds, and I try to vary the size and blade shapes as well. I go by the principle that the smallest knife that can do a job is the largest knife that's right for it. But I still grab a big knife now and again, partly for fun and partly to see that I know how to handle them.
So frequently I grab a Jarvenpaa leuku, flat grind with a convex edge, Bark River Rogue Bowie, and yesterday, Dozier Wilderness knife. Not really surprisingly, any well-made knife has a good range of competence.
I have a koyote with a longer blade than I technically "need" but it's so thin and the convex edge so effective, that it works like a giant paring knife: totally under control even for small tasks.
This brings me to the Mora, another thin blade. When you start with thin stock, you're well on the way to a sharp knife. The particular grind is less important. I do like the puukko style with a "Scandinavian" short sabre grind, but on a thicker, sturdier blade. This gives a good edge for woodcraft while preserving the strength that a single knife in the wilderness needs.
