I remember using those plastic lightweight Wiffle ball bats as lightsabers. They were yellow, too, so you could imagine they were like the Kenner sabers. But the best sabers my friend and I ever had were actually golf clubs with the club end broken off and the broken end crimped down. They were fantastic for duels, though they hurt like hell when you got hit on the fingers. We had to be covert about them because our parents thought they were potentially dangerous. They cut down thistles and sticker bushes like butter, though!
