Merry's sword helped quite a bit if I recall.

So passed the sword of the Barrow-downs, work of the Westernesse. But glad would he have been to know its fate who wrought it slowly long ago in the North-kingdom when the Dúnedain were young, and chief among their foes was the dread realm of Angmar and its sorcerer king. No other blade, though mightier hands had wielded it, would have dealt that foe a wound so bitter, cleaving the undead flesh, breaking the spell that knit his undead sinews to his will.

I don't think normal weapons were as effective so to speak and that is why fire is made mention in particular and the blade of Westernesse as well. There are particular weapons that are more effective than others. Plus how would one get close to the W-k is probably the better question. Most were terrified of them and ran from them; one of their chief weapons was fear.
