>Again, it hasn't come up - who the hell duels with a battleaxe?

I would. A properly trained Axman can use his axe to hook, and disarm or break weapon. Admittedly a battleaxe is more of an assault weapon (it was meant to bash through plate armor), but duels of honor can and did happen between Clansmen.

If you ever followed the Hilander series one of the Immortals was using an axe.

Of Course I'd probably show up to a duel armed with a Prussian Combat Spade.
