A mid-large size camp knife, say 6"-7" blade, uncoated and polished or DC, not too thick, say about 3/16" or even a little less, with a smooth (ala S6) Res-C handle but with a wide exposed tang at the heel for pounding. Imagine the entire heel of the knife as steel but between the heal and the ricasso is the smooth Res-C handle, no exposed tang except for the butt. Make as optional: choil, penetrator tip, fully serrated spine, smooth (NM) or right-angle spine-to-blade transition.

I would order one W/O choil, W/penetrator, serrated spine, right-angle and probably one with just the opposite.
