Admittedly, I've never bothered going the lasher route, but especially after Zulghinlour re-wrote dual wield a few years back so that you automatically dual wield fists, headbutt's not entirely unuseful.

Wield a main weapon, no secondary. You're still getting a possible six attacks, and headbutt away. People just plain don't expect it, and I *think* it's supposed to give you improved combat rounds against someone you stun w/ it.

So...yeah, lasher people? Maybe not so much. Don't take that edge? It's your last chance means of stunning someone that comes with an orc right out of the box.
