Item #: SCP-XXXX

Object Class: Safe

Special Containment Procedures: SCP-XXXX should be contained in a small box made of oak wood in a room with only one door. It should be guarded by at least 2 agents at all times and shouldn't leave its room unless permitted by level 2 or higher personnel. SCP-XXXX should never be accessed by anyone who is not a member of staff. If a subject acquires SCP-XXXX they should be terminated as soon as possible.

Description: SCP-XXXX is a simple knife with a 10 cm long blade which is made of iron, the handle is made of spruce wood. The iron blade cannot have liquid (like honey for example) stick to it and has a slightly blue tint. The most notable ability of SCP-XXXX is the strength of the blade. It is possible to cut any solid materiel using SCP-XXXX, as long as pressure is applied. If it ever comes into contact with blood, it's blue tint will become a red tint or occasionally green. This change in colour does not seem to change any properties of SCP-XXXX in any way.

It doesn't seem to be possible to melt or bend it, even at extreme temperatures. At the moment, it seems impossible to destroy SCP-XXXX by any accessible means. It is unknown if it has always had these characteristics or if it suddenly manifested its abilities sometime after its creation. The creator of the knife has not been identified and the knife is estimated to be roughly 500 years old, possibly even older. There are two letters on the handle, "P.S", that are believed to be the initials of the creator.

If SCP-XXXX is used to murder any human, the user will feel a great urge to murder again. The greater the amount of people killed by the user, the greater they are influenced by it. It is extremely important to make sure that it never leaves its chamber unless it is removed for testing. It also seems to influence people in a small radius of itself by making them feel emotions like hatred, anger and sadness. If they are to leave that radius, they will not be affected by SCP-XXXX and should return to their normal selves within 20 seconds. Interestingly, it's abnormal influence can be neutralized if it is contained in an oak box. It isn't yet understood why only oak can negate SCP-XXXX's influence but it should be noted that SCP-XXXX was discovered in an oak box in █████.

SCP-XXXX, while made of iron, cannot be attracted by magnets nor can it conduct electricity. When attempting to put a magnet near SCP-XXXX, the magnet will begin vibrating slightly and will have no effect on SCP-XXXX. When trying to make a circuit with SCP-XXXX, the battery will explode after around 3 minutes.
