My preference for blade shape, which I admit is largely driven by aesthetics appeal and my "gut feel" about functionality, is something like the ESEE RC-3 or similarly profiled Ontario RAT-3. But I use my Mora Clipper the most of all my fixed blade knives and I find its blade profile to be perfectly functional for day-to-day tasks as well.

I do not (yet) own the ESEE knife, so my preference for its blade shape would be a purely aesthetic thing, now wouldn't it? I've never even held one. I've just seen pictures in online catalogs and decided I like the knife based on that (and also on reviews I've read).
