Equinox Power Blade

An Equinox Power Blade was one of a set of twin Power Swords used by the Space Marines of the Great Crusade and Horus Heresy eras. The set was divided into a "Sunrise Blade" and a "Sunset Blade", each of which had slightly different combat characteristics. The pair were wielded together by a single Astartes in melee combat. The Sunrise Blade was effective at shredding flesh and armour, while the Sunset Blade was capable of sundering even the hardest of substances.
