I've recently been focusing more on axes.  All Gransfors Bruks.  Most recently the Splitting Maul and a splitting wedge.  Of course, those won't be in the backpack.   
I have a little Swedish Wetterlings axe. The handle is a foot long piece of hickory, and the head is forged with a razor sharp polished edge. I put it in my hunting daypack in case I need a little help with the deer pelvis. It is sharp enough for skinning.
