A Plague Knife of Nurgle, favoured melee weapon of the Plague Marines.

A Plague Knife is a long-bladed, dagger-like weapon wielded by Plague Marines and other devotees of the Chaos God Nurgle.

It possesses the capability of "blessing" anyone it touches with the daemonic infection known as Nurgle's Rot. These long, pitted knives are encrusted and dripping with the most virulent of toxins, viruses and other pathogens.

A Plague Knife used by the Plague Marines of the Death Guard Traitor Legion.

Their wielders believe that they have been directly blessed by the Plague God himself, for the rot the weapons carry and spread is so powerful that it can lay low even the most monstrous or powerful of enemies in only Terran seconds.
