An Archangel Blade is an archangel's personal blade. It has similar appearance and characteristics of normal angel blades even though they are far more powerful than a standard angel blade, as they are capable of killing an archangel, thus making it one of the most powerful weapons in the universe. However, the weapon is only effective in the hands of an archangel against another archangel or a vessel powered by an archangel inside of them.
