The Mechanical Pencil is acquired by leaving the Dark World with the Mecha Saber equipped. Much like Kris's other weapons, it is transformed into a type of pencil after leaving the Dark World. The weapon's description in the Dark World foreshadows this new name, as a mechanical pencil's lead can be extended by pressing the bottom of the pencil; exactly what the weapon does.
- The blade extending from the hilt and the name itself may be a reference to lightsabers from Star Wars.
- The weapon wearer gaining the stat "Annoying" may refer to the common habit of repeatedly clicking a mechanical pencil or pen, which creates an "annoying" noise. The Mechanical Pencil's description also alludes to this.
