SCP-5871 - Retroactive Knife

Item #: SCP-5871

Object Class: Thaumiel

Special Containment Procedures: SCP-5871 is maintained in a high-value item locker within Site-03. Usage requires authorization from both the Overseer Council and Ethics Committee.

Description: SCP-5871 is an obsidian ritual knife, with seven unpolished gems encrusting its handle.

The object was discovered in an anomalous burial site within modern-day Mongolia in 1831 and was created in 2020.

As a consequence, utilizing SCP-5871 to symbolically kill an entity (see Document 5871-REST for ritual details) will result in said target being destroyed retroactively. This has proven useful in the neutralization of several dangerous ontokinetic, metaphysical, and temporal anomalies.

Addendum 5871-2: Incident 5871-62

A second, seemingly-identical instance of SCP-5871 was found in Area-313 Deep Storage. The HMCL Supervisor ordered that the object be returned to its unmarked crate, all records of the discovery be destroyed, and all personnel with knowledge of the incident be amnesticized.

O5-9 overrode the directive, instructing that the two anomalies be physically compared. The results of this analysis are attached below:

[LINK ERROR: File 6R0CF/7301567/SCP-5871/6084/8C not found.]

The above document was discovered in the most recent DEEPWELL backup of the IntSCPFN database. Its metadata claims it was filed by Site-03, a nonexistent Foundation facility.
