Corvus Glaive's Glaive

Corvus Glaive's Glaive is a large scythe used by Corvus Glaive as his primary weapon of choice, wielding it during the Attack on the Statesman, Attack on Vision and the Battle of Wakanda, where it was used to kill it's owner.

Attack on the Statesman
Furious at Heimdall for cheating him out of his victory with the Hulk, Thanos motioned to Corvus Glaive to pass him his weapon. Taking the Glaive into his hands, Thanos executed Heimdall with the weapon, before returning the weapon to Corvus Glaive.

Capabilities
The Glaive was created from an incredibly strong material, able to piece the Vision's Vibranium body, as well as being able to deflect the energy generated by the Mind Stone and Shuri’s gauntlets. The blade was able to prevent Vision from phasing or to activate his healing factor, nearly killing him when he is impaled.

Trivia

 * In the comics, Corvus Glaive wields a glaive so sharp that it is capable of splitting atoms, cutting through virtually anything. If the blade remained unbroken, it allowed Corvus to be resurrected from the dead.
