Energy Dagger

The Energy dagger is an energy melee weapon employed by the Sangheili, particularly the Zealot classes, during the Human-Covenant war.

Design Details
The design bears resemblance to the Energy Sword. Unlike the Energy Sword, however, it ends in a single point rather than in dual prongs. The Energy Dagger looks like a miniature Energy sword with a single blade. It is mounted to a device worn on the wrists of the user. It is about half the size of the Energy Sword.

Usage Details
The Energy Dagger is mainly used for assassinations by player-controlled Elites. Other uses include hostage killing, door hacking, wire cutting, and other unknown uses by the Covenant.

Trivia

 * The energy dagger is used in Halo: Reach exclusively by Sangheili in assassinations.
 * Noble Six was almost assassinated by a Sangheili using the energy dagger while investigating Visegrad Relay. The Elite climbed on top of a knocked down Noble Six and proceeded to activate and plunge the dagger downward. Noble Six was able to stop this, however, by grabbing the Elites arm and punching it in the face. It is not shown how effective the blade is in true CQC, as Carter-A259 kicks the Sangheili off of Noble Six and Catherine-B320 sends it back with fire from her M6G.
 * This is the weapon Noble Six was presumably killed with, as a Zealot was seen about to deliver a coup de grace.
 * While a Sangheili (of any class) is in Active Camo, the energy daggers can be seen activated.
 * It is often mistaken as the energy sword in 2 cutscenes
 * It bears some resemblance in both appearance and function to the Hidden Blade from the Assassin's Creed series
 * Energy dagger is similar to Combat knife.
