While Kratos can throw them short distances and use them as grappling hooks, they are ultimately limited by a finite range. Unlike the Leviathan Axe, the blades function as more of a close-range stabbing cutting weapon than a projectile.
Why doesn t Kratos use the Blades of Chaos anymore?
Symbols of a shameful and particularly painful past, Kratos indeed swore to bury them forever, never to be used again. Although these cursed weapons have been replaced by the Leviathan Axe, the Spartan reluctantly carried them once more out of his love for his son, eventually saving the latter's life.
Replacing the old Blades of Chaos, this weapon personifies the change of heart and personality of the Ghost of Sparta by the time he inherits the Axe, having long abandoned the path of destruction he caused with his former Blades.
Being magical, the Blades of Chaos possess multiple unique properties. Their fiery aura can cut through almost any obstacle, including the frosty creatures of Helheim. Since the Blades of Chaos are affixed to Kratos via a pair of chains, they can also return upon command.
The weapon carries immense power and is the only thing that can stand up to the might of Mjölnir. Following its creation, the axe was gifted to the protector of Midgard and Giantess, Laufey. As a protector, Laufey was a fierce warrior and was often seen keeping the people of Midgard safe from the wrath of the Gods.
Although Kratos never gets to wield the hammer, given his own extraordinary godly strength that slightly surpassed even that of Thor and even being able to hold Mjolnir back with his bare hands when Thor threw it at him, it's very likely that Kratos would be fully capable of using the hammer if he wanted to.
They were last seen discarded by Kratos after he had forced Zeus' soul back into his body. Though considering how the chains on Kratos' arms were loosened upon Zeus' death, it could simply be implied that he no longer had use for the blades with his quest (and their main purpose) was complete.
Are the Blades of Chaos better than the Leviathan Axe?
Unlike the Leviathan Axe, the blades function as more of a close-range stabbing cutting weapon than a projectile. During Kratos' time in the icy north, the Leviathan Axe proved to be ineffective. On the other hand, the Blades of Chaos could melt through frosty opponents with ease.
However, when Kratos fell into the River Styx, the blades were destroyed and rusted by the souls that attacked and drained him of his power. Afterward, the Astral Form of Athena took the ruined blades and transformed them into the Blades of Exile.
According to an early God of War script, the character is 7 feet 0 inches (2.13 m) tall, but this was later changed when Santa Monica Studios and Gnomon School delved deeper into the animation and rigging history of the games, showing Greek Kratos to be 2.34 metres (7 ft 8 in) tall, with Norse Kratos being 1.94 metres ...
They forged the Leviathan Axe as a weapon to counter Mjolnir, and as a form of partial penance. It was given to Laufey, Atreus' mother, who passed it on to her husband, Kratos, before her death. The Leviathan Axe's name is inspired-in-universe by Norse mythology's own giant sea creature, the World serpent.
In the Novel, it was revealed that the Blades of Chaos were forged by Hephaestus, but in the first game, it was mentioned that they were made in the Underworld by Ares.
In the very end, Kratos ultimately used the Blade to stab himself, and thus, released the power of Hope that dwelt within him, as well as the power within the Blade itself, which was rendered useless. The sword was last seen in the ground of Zeus Battle Arena, abandoned, following Kratos' disappearance from Olympus.
They mention the reason in one of the "boat conversations." Simply put, Kratos feels weaker because he is weaker. His domain is gone, destroyed along when he completed his revenge against Zeus, which means no tribute or worshippers. His godly power is dwindling, and may one day be gone completely.
To say that the relationship Kratos has with his iconic Blades of Chaos is a complicated one is an understatement. Throughout the series, Kratos has shown his hatred for his signature weapons, despite how often he has needed them.
God of War's combat is impressive, and while Mjolnir could have been a worthy addition to Kratos' arsenal, it wouldn't fit the character's arc based on William's logic. The Norse Saga has transformed Kratos from a ruthless and bloodthirsty anti-hero to a protagonist with real depth.
Now if we're using their current selves, it's an instant loss for Kratos, because while he has weakened, Thor only grew in power. He possesses the full power of the Odin-Force, renamed into the Thor-Force, and far surpasses Kratos in power. Even Young Kratos would be no match for King Thor.
Unlike the others, Zeus is not worthy to lift Mjolnir, but through a loophole, he can anyway. If Mjolnir is to enter his domain, Zeus's MCU powers should override Odin's enchantment, meaning he can hold Mjolnir.
