'''Vyre's knife''' is a bright golden or yellowish-white[[raysium]] blade with a sapphire set into the pommel, used to kill the [[Herald]] [[Jezrien]] and trap his soul so that he couldn't be reborn.{{book ref|sa3|121}} The metal of the knife is described as unusually bright.{{book ref|sa3sa4|12184}}
 
The knife is made out of [[Odium]]'s [[God Metal]], [[raysium]].{{book ref|sa4|84}}

The knife can kill a Herald by trapping the soul, preventing the Herald from returning to [[Braize]] as a "conventional" Herald death would.{{wob ref|12261}} Jezrien, while initially in a drunken stupor, quickly realizes that something about this death is different and claims to feel the knife drawing something from him into itself. [[Shalash]] likewise instantly distinguishes it from previous deaths, as she could no longer sense Jezrien's soul.{{book ref|sa3|121}} The knife "traps" the soul so it can't be reborn.{{wob ref|12261}} This process operates under similar principles to the [[Scadrian]] manifestation of [[Investiture]] known as [[Hemalurgy]],{{wob ref|8774}} where practitioners are able to steal part of an individual's [[spiritweb]] using metal spikes.{{book ref|mb4|part=ars}} It would cause debate among [[cosmere]] philosophers whether the knife's magical properties are in fact Hemalurgy or rather a related, but distinct, phenomenon.{{wob ref|8665}}

Following Jezrien's death, the sapphire set into the knife takes on a "subdued glow". The sapphire in the knife's hilt is specifically for Jezrien.{{wob ref|8798}} Whether the use of that specific [[polestone]] is mechanically relevant or only symbolic is unknown.
