- "And though my soul departs the Earth, I count my days till my rebirth. I will wait across eternity for my love to come back to me"
- —Priestess Chay-Ara reading the dagger's inscription[src]
The Amon Dagger is a mystical Egyptian relic that was a present from Prince Khufu to Priestess Chay-Ara. It consists of the Nth metal and was used by Vandal Savage to kill Khufu and Chay-Ara. Thought to be magic, it is later revealed in Legendary that the Nth metal in the weapon is Thanagarian technology.
The Amon Dagger was given to Priestess Chay-Ara by Prince Khufu four thousands years ago. It was sacred, and it was said that only a high priestess could read its inscription. Vandal Savage, who at the time was known as "Hath-Set", eventually discovered that Khufu and Chay-Ara were lovers. Enraged, he used the Amon Dagger to first kill Khufu and then Chay-Ara.
After the death of Aldus Boardman, Carter Hall and Kendra Saunders found a newspaper article about the dagger kept in his suit, revealing that the dagger was sold to a Russian named Sasha Mahnovski on September 21, 1975. Recognizing the dagger, and since the dagger was involved in their first lives' death, Kendra and Carter realized they could use it to kill Savage. While Carter tried to help Kendra remember the dagger's inscription, which she eventually did, Ray Palmer, Leonard Snart and Mick Rory head out and tried to steal the dagger from the Russian, which turned out to be harder than expected since the owner was Vandal Savage. He asked them to call the rest of their team, who later arrived at the scene. Carter tried to kill Savage with the dagger, only to learn that Kendra must be the one who wields the dagger for it to be able to kill Savage. He then was stabbed by Savage with it, dying only a few seconds later.
- Meteorite exposure: The Amon Dagger, like the Staff of Horus, was exposed to the same meteorite that destroyed ancient Egypt.
- Energy projection: The dagger, having properties of Nth metal, can fire blue energy similar to the Staff of Horus.
- Inscriptions: Written in lapidary hieratic, the inscription is a love poem that promises eternal love.
