Acquired from It’s a Wrap, this is one of three stunt Sword of Kahless that were made for the Deep Space Nine episode “The Sword of Kahless” and then reused in the Star Trek: Voyager episode “Prophecy”.
When it came on eBay in fall of 2008 I was on the set of Battlestar Galactica and remember calling Max Cervantes, the well known propmaker, and asking him about the swords. He told me that three stunt swords were made.
Another stunt sword surfaced recently and my good friend and fellow big Star Trek collector Donna Sakaida bought it. Though not from an offical source it proved similar to mine.
