Is that a Sundang in Oliver Queen's hand?

I hazard to bring up such trivia in this important forum,but while watching the final season episode of "The Arrow," I almost fell out of my chair when Oliver Queen was dueling Ra's al Ghul and I believe they were both sporting Sundangs.I don't know if they were engaging in the proper forms of Eskrima, but I hope the swords don't become more expensive due to their exposure on this show !
