Item #: SCP-25565

Object Class: Euclid

Containment procedures: SCP-25565 must be contained in its sheath at all times when not in use and stored in a locked storage container at Site-06. When not locked in its storage container, SCP-25565 must be strapped to the back of a human being, preferably male. If SCP-25565 is unsheathed for any purpose other than combat, it must take a life before being allowed to be re-sheathed.

Item Description: SCP-25565 takes the form of an old antique Katana. The blade measures 76.22 cm in length and is gently curved with a black luster sheen, it has pit marks and scratches along the sharp edge and face of the blade. SCP-25565's hilt measures 27.94 cm and is black wrapped in dry, cracked, red leather strips. It's hand guard resembles that of a dragon eating its own tail in a dark brass color with the pommel cap matching the décor. On the sheath is a black background with dark maroon patches resembling blood splatters; another dragon in the same brass color as the rest of the sword curls around its length.
SCP-25565 has three anomalous properties none showing any correlation to the other.
If SCP-25565 is unsheathed for any non-combat purposes, it requires the user to kill another living being before SCP-25565 will allow itself to be re-sheathed. Testing with robotic entities have had no effect on nullifying that anomaly.
When SCP-25565 comes into contact with non-male subjects, SCP-25565's blade will become dull and rusty becoming unusable again until it comes into contact with another male. Again, testing with robotic entities have no effect on nullifying the anomaly.
SCP-25565 when used in combat scenarios has the ability to cut through any material regardless of hardness or thickness including [DATA EXPUNGED]. This effect cannot be used on its own sheath or the user of the blade, when the subject attempts to cut either the sheath or themselves, they feel an overwhelming desire to stop and will have to take the life of another living being before re-sheathing the blade. Testing with robotic entities have again, no effect on nullifying this effect.
