So. The idea i had was for a Safe-Class SCP that takes the form of a meat cleaver commonly used by butchers. It does nothing unusual when left lying about, but once picked up by any human being it starts to affect that person psychologically.
They will be mentally unable to let go of the cleaver (it doesn't fuse with them like SCP-198) and begin to experience increasing schizophrenia and react increasingly violent to any attempts to remove the SCP by force. Eventually they will begin to see other living creatures as grotesque monsters that want to harm them, forcing them to try and kill those monsters despite them appearing normal to anyone else.
That's the general idea for the SCP. What do you think? Is this worth expanding and/or refining or should i abandon this idea? Tell me your thoughts, but please try to stay constructive.
