I usually take one of my "Camp" knives in the 7"-8" range like my Ratweiler or RD7, SwissBianco +B One Hand Trekker, and a SwissTool. I have found very little that I can't get done with that combo. With that being said, I will say that with a high quality axe like a GB or a Hultafors, you can do anything that you can with a large chopper and a lot of it even better.
I do also usually have a neck knife on a necklace rig.
