Aurra Sing's lightsaber

The bounty hunter Aurra Sing had a scarlet-bladed lightsaber. Sing didn't construct the lightsaber herself, but took it from one of the Jedi she killed.

Prior to the Invasion of Naboo, Sing used it to kill Jedi Knight Mana Veridi on the planet Kwannot and later wielded it in combat against Qui-Gon Jinn and his Padawan Obi-Wan Kenobi.

In 27 BBY, Sing carried her lightsaber while on the search for the rogue Jedi Reess Kairn.
