My Generic Combo would be:
1. Large Fixed blade (chopper)
2. Small fixed/large folder (camp chores and all round user)
3. Multi-tool / SAK
So, I have several combo's I could go with.
1. HeavyHeart
2. Mora Clipper
3. Champion SAK (Like Champ, but older)
or
1. BK1
2. Wenger Mountaineer
3. gerber Mutli-tool
or
1. Ontario Machete
2. Becker Necker
3. Champion
Or, maybe packing a little smaller and lighter, slide down the weight/size scale and the RAT-7 becomes the "medium" chopper, replacing the big burly blades. Depends on season, terrain, etc.
and so on...... Mix and match.
For large Chopper you could substitute your hand axe, I prefer a large blade, it really just is a matter of preference.
I always try to make either 2. or 3. to be in Stainless, for food prep, again, you can prep food with carbon steel, no problems, but I prefer stainless when possible.
Also, like to have a little saw on one of them, that's why the Multi-tool, Wenger or Champion is always somewhere on the list.
