I’m not too sure why the smaller knife should be a folder, seems like a Nessmuk concept to me (which is totally fine btw) but Mr. Janowsky does not mention having multiple blades in his folder. For me, a second fixed blade in a sheath or otherwise attached to your body is adequate. I would also throw in a multitool and a folding saw (both on my person) as well as a medium axe and a crook knife in my pack. Generally a dedicated skinner and/or a fillet knife will also be in my pack depending if I’m in the field or on the water (or both).
That ends up as:
a Large and small fixed blade, saw and multi-tool on my person and
a medium axe, a crook knife a skinner and /or a fillet knife in my pack.
I could perform any chore with what’s on my person if I should lose the pack. However, having the pack makes life easier and more pleasant.
