Pont-Saint-Esprit Bread Knife

Origin
On 15 August 1951, an outbreak of poisoning, marked by acute psychotic episodes and various physical symptoms, occurred in Pont-Saint-Esprit. More than 250 people were involved, including 50 persons interned in asylums and four deaths. Most academic sources accept ergot poisoning as the cause of the epidemic, while a few theorize other causes such as poisoning by mercury, mycotoxins, or nitrogen trichloride. It was also hypothesized that it was managed by the Central Intelligence Agency as part of its Project MKUltra.

Effects
Used to prepare bread contaminated with hallucinogenic mold in 1951, the toxins seeped into the blade itself. Now any food cut by the knife will induce terrifying hallucinations when ingested. The user may become compelled to attack the visions or induce self-harm.
