This article's title is uncanonical and a fan created one, because an official term or name has not been made yet.

Vyre's knife is a golden, or yellowish-white, blade, with a sapphire set into the pommel, used to kill the Herald Jezrien.

History

The circumstances of the knife's creation are unknown. It was given by the Fused Hnanan to Moash, who then used it to kill Jezrien. The fate of the knife following Jezrien's death is also unknown.

Mechanics

The knife appears to be a method to permanently kill a Herald, rather than simply returning them to Braize as a "conventional" death would. Shalash, who was able to feel her father's death, instantly distinguishes it from previous deaths. If he was killed conventionally she would still have been able to sense her father's soul, but in this circumstance she could not. This process operates under similar principles to the Scadrian manifestation of Investiture known as Hemalurgy, where practitioners are able to steal part of an individual's spiritweb using metal spikes. It is a matter of debate among cosmere philosophers whether this is in fact Hemalurgy or rather a related, but distinct, phenomenon.

The sapphire in the knife's hilt is specifically for Jezrien. Whether the use of that specific polestone is mechanically relevant or only symbolic is unknown.

“Was, was, was . . .” The man started to tremble violently, his eyes opening wide. “Was . . . no. No, what is this death? What is this death!”

Huddled forms stirred, and some of the wiser ones scuttled away.

“It’s taking me!” the man screamed, then looked down at the knife in Moash’s hand. “What is that?”

The man trembled for a moment more, then jerked once, going motionless. When Moash pulled the yellow-white knife free, it trailed dark smoke and left a blackened wound. The large sapphire at the pommel took on a subdued glow.
