Rhitta

The is a sacred treasure belonging to the Lion's Sin of Pride, Escanor.

Appearance
Rhitta is giant ornamental axe with a blade shaped like a crescent moon, similar to that of a Monk's spade. It's design specs and distribution of weight are (likely intentionally) off: most of the weight is concentrated in the head, leaving it off balance, and even more difficult to wield than it's impressive weight would already make it.

Abilities
The abilities of Rhitta involve an ability called "Fire and Charge" the axe absorbs all of the excess immense energy emitted by Escanor's unique body and stores it within itself gathering large amounts of magic power. However it appears to be incredibly heavy, though Escanor can lift it with ease during the daytime when other such as Meliodas struggle to hold it. Escanor has been shown to also use it in conjunction with his Sunshine power, allowing his strikes to be augmented with the flames from Sunshine, burning foes.

Escanor can also summon the axe to his location whenever he wishes. This bypasses the inconvenience of its weight when he cannot carry it during the night. The axe flies to his location at incredible speed.
 * Fire and Charge: This ability simply gathers Escanors excess heat and magical energy expelled by Escanor waiting for it to be released and fired.
 * Sunshine: Escanor uses his Sunshine power through Rhitta allowing its slashes to burn and incinerate enemies.

True Divine Axe Rhitta
It is activated with the command"Sacred Treasure Release"「神器解放 Jingi Kaihō」doing this releases Rhitta's true power. It releases all of the magic power gathered by the axe in one instant. The sunshine power being so immense that it is able to make night seem like day and making others mistake it for the sun itself. The amount of magic power released can be compared to a power of a member of the Ten Commandments. And when used in an attack can incapacitate two immensely powerful enemies and cause massive destruction, heat and fire at the impact.
 * Fire and Charge: This ability gathers Escanors excess magic power and heat that is released over time and can fire it in one devastating blast.
