Bloodblade

A Bloodblade is the name provided to red-colored fireblades used by the Covenant and its remnants.

Design details
Bloodblades are not exclusive to a specific pattern of fireblade, as they have been seen as s, s, and two unidentified patterns.

Usage
Bloodblades were used by some Special Operations Sangheili, such as the Silent Shadow. One of their known uses was at the Battle of Algolis, during the Human-Covenant War, in the attempted execution of Atriox. They were also seen in the defense of a Covenant moon base. Bloodblades were also in use with the Banished, with one being in the possession of Jega 'Rdomnai as his personal energy sword during the Battle for Zeta Halo in 2560. After he was defeated by John-117, the Spartan kept 'Rdomnai's personal Bloodblade as a memento.

They were also sometimes used in the UNSC's War Games simulation, for example in Infection sessions.

Halo 2: Anniversary
The Bloodblade is exclusively used by zombies in Halo 2: Anniversary's Infection mode.

Halo Infinite
The Elite Bloodblade is a special weapon in the campaign of Halo Infinite. It can be acquired and wielded after the player has defeated Jega 'Rdomnai in House of Reckoning. It provides additional stat boosts even greater than that of Okro 'Vagaduun's Duelist sword. It can be acquired at any Forward Operating Base following the completion of the level.
