Space Sword Blaster
Act 30 - Sailor Uranus Haruka Ten'o Sailor Neptune Michiru Kai'o (manga)
When the sword was brought together with the other talismans, the Deep Aqua Mirror and the Garnet Orb, it produced the Holy Grail. The sword's blade was red, and was often concealed with a jewel-decorated sheath. The handle of the sword was golden. In the Sailor Moon Supers Movie, Sailor Uranus uses this item to cut Oranja's flute resulting in Oranja himself turning into a pink cuckoo bird, and then Pupulan's flute turning Pupulan himself into a blue hummingbird.
The blade of the Space Sword in the manga was silver, and was much longer than it was in the anime. However, it seems to have the ability to shrink to the size of a dagger or short sword. It, along with the other two talismans helped power the Holy Grail. But their initial function was to awaken Sailor Saturn.
In the Sailor Moon musicals, the Space Sword had the same appearance as in the anime, but its blade was silver, and did not have a sheath to cover it.
When Galaxia tries to take Uranus and Neptune's star seeds, Uranus attempts to hit Galaxia with the sword, only for Galaxia to dodge the attack.
Sailor Uranus summons the sword when she fights Viluy. Using Space Sword Blaster, she unleashes powerful projectiles, destroying Viluy
- In the Cloverway dub, It was referred to as a saber.
