Razor Edge

Razor Edge (レイザーエッジ) is a magic sword once wielded by Gazef Stronoff. It is currently in the possession of Brain Unglaus.

Description
This magical sword is one of the five treasures of the Re-Estize Kingdom. It is a national treasure given only to the nation's strongest warrior.

Appearance
It is a large glowing magical broadsword with an elaborate hilt similar to Gazef's normal weapon he uses.

Abilities
Razor Edge is a magically sharpened sword with the ability to slice through armor like paper. However, according to Ainz Ooal Gown's analysis, its sharpness is just one of it abilities. In fact, the sword has as much data or mana imbued like those weakly enchanted objects that it shouldn't be able to hurt him. Still, the very fact that the sword can cause him harm despite what he understands to be true makes it an impressive sword in his eyes.

Trivia

 * Ainz Ooal Gown admitted that Razor Edge can be used to kill him.
