The Twin-bladed Knife is a powerful Void artifact which created the Outsider and has the power to end his existence.

The knife is described as bronze, with twin straight blades that are 12 inches long[2], and has the same guard as an Overseer Sabre. Despite its age, it is still a masterwork of blacksmithing, capable of slicing through flesh and bone with ease.[3] It was used by cultists two thousand years before the Great Burning to sacrifice the outcast boy who would become the Outsider. The ritual imbued the knife with powers from the Void, and can grant its bearer with abilities akin to those with the Outsider's Mark. It was lost to time during the millennia after the ritual.

The Corroded Man[]

Main article: Dishonored: The Corroded Man

The Twin-bladed Knife resurfaces around 1848-1849 in Utyrka, a Tyvian salt mine and labor camp. Zhukov, a former Hero of the State betrayed by his nation, finds it in a long forgotten shrine discovered by his fellow prisoner Milosch. Upon its sight, he became enthralled by the knife, overwhelmed with visions and whispers. He gives away to madness and stabs Milosch before carving out his victim's body to make bone charms. The knife then continued to show him visions on how to use his new-found abilities through the crafting of powerful corroded bone charms, able to mimic supernatural abilities without any effect by the Ancient Music but limited in longevity. He then hatches a plan to escape Utyrka and rewrite his own past.

In 1851, Zhukov brings the Twin-bladed Knife to Dunwall with the hope of gathering ingredients for a black mirror that can show past, present and alternate timelines. Upon its completion, Zhukov fuses the knife with the black mirror. After the mirror shatters, the knife is brought back from a shard by Emily Kaldwin and then used by her father Corvo Attano to kill Zhukov. The Twin-bladed Knife seemingly disappears along with Zhukov's body during the destruction of Greaves Auxiliary Whale Slaughterhouse 5.

In 1852, in the midst of Delilah Copperspoon's usurped rule on the Empire of the Isles, Daud returns to Dunwall to seek an artifact said to have the power to kill the Outsider.

Death of the Outsider[]

Main article: Dishonored: Death of the Outsider

Two months following Emily Kaldwin's return to the throne, Daud contacts Billie Lurk in Karnaca in order to help him achieve his quest of killing the Outsider. Billie is first tasked in locating and recovering the Twin-bladed Knife, which was obtained by the Eyeless gang and locked in the Dolores Michaels Deposit & Loan Bank in Upper Cyria.

After collecting it, the knife grants Billie Void Strike, a supernatural ability that can stun and project enemies. When not in use, the knife dissolves into multiple small shards and merges with Billie's arm. Obtaining the knife grants Billie Lurk the Bonecharm Crafting ability.

The Veiled Terror[]

After the fall of the Outsider, the Knife lost its Void Strike ability.[5] Summoning it only worked half of the times, the other half sent blinding pain up Billie's Black Shard Arm. One such attempt ended up with Bille waking up in a cabin in a Tyvian forest, without having any memory of the previous week. She became afraid of summoning the weapon, and stopped using it all together. However, she later learned to control her fear, thus control the Knife itself.
