Which do you consider canon?

Which of Mace Windu's lightsabers do you consider canon? At the end of The Phantom Menace, he seems to have Kit Fisto's saber attach to his belt, but the visual dictionary shows us one akin to Plo Koon and Luminara Unduli. I know it's barely visible on-screen, but I'd say the Fisto saber would be his real saber.
