Kronos with the scythe in Percy Jackson's Greek Gods

Kronos' Scythe is Kronos' symbol of power. It was gifted to him by his mother Gaea to dethrone his father, Ouranos. His own son, Zeus later used it to cut Kronos into pieces and banish the remains to Tartarus. It was also wielded by Luke Castellan in the form of a sword known as Backbiter, a weapon made of steel and Celestial Bronze.


The Scythe was initially forged by Gaea, for her one Titan child who would dare to wield it against Ouranos. Only Kronos, the youngest, but the bravest and craftiest agreed to do so. While Ouranos was held down by Hyperion, Iapetus, Krios, and Koios, Kronos brutally castrated his father with the Scythe, and proceeded to slice him into a thousand pieces. Shortly thereafter, Kronos became Titan King of Mount Othrys, making the mighty Scythe his personal symbol of power. While not wielding it, Kronos would hang it on the wall, beside his Black Throne. His siblings would take to rarely visiting him, as they feared his infamous scythe.

After Kronos is finally defeated in the First Titan War, Zeus takes the Scythe from him, and proceeds to slice his father into a thousand pieces, and hurl them into Tartarus.

Percy Jackson and the Olympians

The Lightning Thief


Luke with Backbiter

Shortly before the events of The Lightning Thief, Luke swears an oath of unwavering loyalty to the Titan King, and gets ahold of the scythe, though in its sword form, Backbiter. Luke was first seen using Backbiter in the Sword Fighting Arena. Luke used the sword to rip open a portal and vanish from Camp Half-Blood.

The Sea of Monsters

Luke used the sword again on the Princess Andromeda to fight Percy, and succeeded in wounding him. Percy said that his leg felt like it was on fire.

The Titan's Curse

Luke used the sword to fight Thalia. In the end, however, Thalia prevailed, knocking the sword out of his grasp.

The Battle of the Labyrinth

Luke did not have his sword, as it was being reforged back into the scythe by the Telekhines that work for Kronos. According to Percy, the scythe looks so terrifying, that his "blood turned to ice" when he saw it for the first time.  

The Last Olympian

Kronos is seen using his scythe many times throughout the Battle of Manhattan. When Percy, Grover, Thalia, and Annabeth go to Olympus, trees are shredded, ground leveled, and paths were turned to rubble. It is said that this was caused by the scythe. In his final fight with Percy, Kronos turns his scythe back into Backbiter because Percy challenged him to a sword fight. During the battle the sword was knocked into Hestia's hearth, but when Kronos tries to retrieve it, Hestia superheated it so he couldn't touch it. With the destruction of Kronos, it melted into a pool of molten metal. It is unknown if Hestia did this, or if it was destroyed when Kronos was defeated, though both are possible.


Kronos' scythe is an extremely powerful weapon, surpassed only by Poseidon's trident, Hades' helm, and Zeus' master bolt. One hit from the scythe can release enormous amounts of energy into a person, "severing their soul from their body" with a single touch. Because of its blade, which is made of half steel and half celestial bronze, it can harm both mortals and immortals alike. The scythe can even be used to destroy the bodies of immortals, as it did with both Ouranos and Kronos. It can also be turned back into its sword form, Backbiter.


The Scythe is six foot long, blade curved like a crescent moon, with a thick handle wrapped in leather. The blade of the scythe is made from the same material as Backbiter, meaning that it is a mix of tempered steel and Celestial Bronze. According to Percy in The Battle of the Labyrinth, the Scythe looks so terrifying, that "[his] blood turned to ice" when he saw it for the first time. As shown in Percy Jackson's Greek Gods, all of Kronos' siblings, nephews and nieces rarely visited him, since they all secretly feared his wrath, and his mighty Scythe.  


Kronos, owner of the Scythe.



  • As shown in Percy Jackson's Greek Gods, the scythe was initially forged for Kronos by Gaea herself. Hence, Kronos' scythe is the first known symbol of power created for an immortal.
  • Kronos' scythe is the only known divine weapon that has destroyed the bodies of two immortals (Ouranos, and later Kronos himself).
  • As seen in Percy Jackson's Greek Gods, Kronos would often hang the scythe on the wall, beside his black throne.
  • While the scythe was being reforged by the telekhines, it was cooled in blood. This is a process that the Norse use when crafting bone steel.
  • In some myths however, the scythe is described as a blade made of flint, diamond, or adamantine, a mythical metal from Tartarus, said to be indestructible.
