I like my big choppers (BK4, BK9, Ontario SP8, etc...), they're very fun, but it's not the most practical thing out there. A decent 4-6" blade is enough, doesn't even need to be full-tang. No point in trying to baton with it, I would just whittle some wedges and use those, it's much easier on the knife and safer. For serious outdoors excursions, pair it up with a saw (folding saw, buck saw, or even a chainsaw, whatever the situation calls for) and a proper axe.
