Variants

Cheap Copy of the Left Nut of Petrus

The cheap copy of the left nut of Petrus is a randomly found treasure item worth very little money. As the name implies, it is a shoddy glass replica of the Left Nut of Petrus - an important quest item. It would be very difficult to get the two confused however.
It has no use beyond being sold to a shop for little gold.

Expensive Copy of the Left Nut of Petrus

Unlike the cheap copy, an expensive copy of the left nut of Petrus is made of diamond and therefore worth considerably more money when sold.
Its name is making fun of the common use of "cheap copy" to describe knock-off products, as "cheap copy" implies there may also be an "expensive copy".

The Left Nut of Petrus

The Left Nut of Petrus is a unique quest item required to attain one of the game's many endings. It is physically the same as a regular nut, except that it cannot be polymorphed or destroyed in any way, emits a faint glow, and possesses an absurdly high strength modifier when used as a weapon.
It can only be obtained by defeating Petrus in battle, which can be attempted at any point in the game. After receiving the nut, attempting to leave Attnam will end the game and trigger a specific ending.
