Pretty sure the Ragna Blade came first. To my knowledg BBoD was first mentioned in The Drow of the Underdark novel, written by Ed Greenwood in 1991. The Ragna Blade comes from the Slayers novel series which was first published in 1990 in Japan.

Or it could be that the two things were conceived independently. A black magical blade that destroys everything in its path is not really a unique idea.
