10 Most Powerful Weapons In Star Trek

10. The Sword Of Kahless

The first bat'leth ever forged, the Sword of Kahless was a revered item to the Klingon people. It held the same significance in their history as the Holy Grail holds to Human history. It was used by Kahless to instigate the founding of the First Empire and then held in worship following the leader's death.

The item was stolen by the Hur'q during their invasion of Quo'nos, with many fakes cropping up over the years. However, in 2372 a Vulcan survey team discovered a tattered piece of the shroud that covered it on a planet in the Gamma Quadrant. Dahar Master Kor recruited Worf and Dax to help him find it.

The true danger of the weapon became apparent once they and Torral, son of Duras, met on the distant planet. The cultural significance of the blade was enough to drive even the closest friends apart, as evidenced when Kor and Worf came to blows. All three of them feared that if it were to return to Quo'nos, civil war would not be long in following.

While it may physically be the least dangerous on this list, symbolically it has the power to destroy a world.
