Item #: SCP-XXXX
Object Class: Safe
Special Containment Procedures: SCP-XXXX is to be kept within a standard locker measuring at 1800 mm tall, and 300 mm by 300 mm wide at Site [REDACTED]. Interaction, transfer, and use of SCP-XXXX requires level 2 security clearance and supervision.
Description: SCP-XXXX is a hand powered fence post pounder from an unknown manufacturer. It is 800.1 mm long, with a diameter of 57.15 mm, and weighs 9 kg. It was discovered on a farm in [REDACTED], Missouri.
The anomalous nature of SCP-XXXX manifests when someone uses it to pound standard 1.83 m t posts typically used in fencing for livestock containment. When someone uses SCP-XXXX, they will not experience any bodily fatigue or muscle soreness typically associated with such labor until after the intended amount of posts required for the job are pounded into the desired surface. There appear to be some exceptions to this rule. A person will not experience fatigue so long as they continue to pound fence posts at the initial project location within 3 days of stopping, allowing for the user to stop for a brief time period if they wish. If they do not continue within the 3 day period, they will experience the bodily fatigue and soreness of the work they managed to complete, and will continue to feel this discomfort until they start using SCP-XXXX once again to continue the project. If they stop again, the 3 day rule applies once more, but if they rest beyond 3 days, the amount of labor they completed will have a cumulative effect on the amount of fatigue they feel, thus making them experience the full amount of stress their body has gone through. Users may stop any time during the project and enjoy the 3 day break period as often as they like, but if they rest beyond that timeframe, they must return to the project in order to alleviate the discomfort until the project is completed, upon which they will experience full fatigue and soreness.
Another exception is that no user will experience fatigue unless they pound in a minimum of [REDACTED] posts within a given job. The “intended” amount of posts is the full number of posts the user truly intends to pound into a surface, regardless of any time intervals between usage of SCP-XXXX. For example, when a user intends to pound only 40 t posts for a day’s work, but knows they will eventually end up pounding 200 posts to complete the project, they will not feel any fatigue (subject to the other rules listed above) until they have pounded in the full 200 posts. When a person attempts to use SCP-XXXX to insert t posts of an unknown number, as in, they are unaware of the amount needed to complete the project, SCP-XXXX will not permit the insertion of t posts into any given surface, no matter the effort the user exerts in their downward strikes.
Another anomaly associated with SCP-XXXX is that, no matter what surface the post is being pounded into, the pounder will sufficiently put the post into the surface with only two downward strikes. D class subjects using SCP-XXXX have all been shown to strike t posts with SCP-XXXX at exactly [REDACTED] Newtons of force, regardless of their physical conditioning, and all posts, regardless of what surface they are being pounded into, will not be pounded further than 393.7 mm from the bottom of the t post. Experiments with SCP-XXXX have resulted in t posts being put through concrete, steel, solid rock, and numerous other surfaces. So far, no experiments have found a surface in which SCP-XXXX is incapable of inserting a standard t post inside of it. None of the above-mentioned anomalies will manifest with SCP-XXXX unless it is used with standard t posts. No other materials, be it rods, pipe, wooden poles, etc will cause the user to experience any abnormal phenomenon, and SCP-XXXX, quite ironically, will seem to behave as a standard fence post pounder due to the absence of standard t posts.
As alluded to previously, the amount of fatigue a user experiences seems proportional to their physical conditioning prior to usage of SCP-XXXX, and the amount of posts pounded before the user stops. Experiments with D class personnel have shown that those with larger, stronger muscle fibers do not experience the same levels of fatigue as individuals with smaller and weaker muscle fibers. Likewise, the more posts the user inserts, the greater the fatigue and muscle soreness they experience. It is not recommended that any person, regardless of physical capabilities, attempt to use SCP-XXXX to insert large numbers of t posts into any given surface. Experiments with D class personnel ordered to pound large numbers of posts have resulted in serious injury and death. One D class was ordered to insert a staggering 500 t posts at Site [REDACTED], and completed the task in an astonishing 2 hours. After the D class was finished, he immediately collapsed to the ground in great pain. Medical examinations of his body revealed he was suffering from extreme rhabdomyolysis. Subject died 40 minutes after initial collapse.
Foundation researchers have found a way to navigate SCP-XXXX’s more dangerous effects while still being able to utilize its efficiency in inserting t posts into surfaces, allowing the foundation to use SCP-XXXX to construct simple barbed wire or electric fencing with greater speed and cost effectiveness than most conventional methods. For unknown reasons, SCP-XXXX seems to act upon the users own knowledge of the task at hand, in particular the amount of fence posts the user intends to insert into the ground. Researchers have found that when D class subjects are ordered to pound in a certain number of posts, and only that amount, SCP-XXXX will consider that number known by the D class to be the only required amount of posts for the given job. This allows for teams of people to use SCP-XXXX repeatedly while minimizing the fatigue they experience, so long as team members are not ordered to insert large amounts of posts on their own. No foundation personnel or D class subjects are to be ordered to insert more than [REDACTED] t posts at a time.
