In J. R. R. Tolkien's Lord of the Rings lore there were present the common types of weapons as bows, arrows, spears, axes, pikes, maces, swords, etc.
In high fantasy, swords have played a preponderant role. Particularly, in Tolkien's epic novel The Lord of the Rings, the word 'sword' appears 330 times in its three volumes: 87 in The Fellowship of the Ring, 125 in The Two Towers and 118 in The Return of the King, the most famous sword being Narsil, the Sword of Elendil.
I don't know why, but I have always thought that Sauron had a sword. I have been researching about it and even though LotR fandom tags the sword among Sauron's weapons, it doesn't describe or elaborate about it.
The only mention of the sword of Sauron is in the card game The Lord of the Rings by Fantasy Flight games where it is called the Black Sword of Sauron used by a captain named Sahír: a corsair enemy.
I have tried to detail in Peter Jackson's movies if Sauron uses a sword, and I think I've seen a sheath at his waist, but I am not sure. I only see is his mace.
I want to know if within Tolkien's legendarium Sauron has a sword.
