the Energy Sword is a weapon from the Halo universe, carried primarily by sangheili but also by the Master Chief.

Halo Energy Sword

At full charge, it has about twenty uses, though even when used up the blade remains, quite solid, hinting that is not the magentic field which is reduced.


The sword is, when inactive, a handle containing a large power source.

When activated, it is theorised that a large magnetic field in the shape of a blade is created, then filled with plasma. This field is strong enough to hold the plasma together while slashing at opponents.


The energy sword releases a quantity of energy on impact, primarily heat. This damages armour. The magnetic field makes the sword 'blade' as strong as a metal blade or stronger, and quite capable of going through metal, flesh and bone.
