Split the barrel in half, flip it open, make them go flat, then release a bladed edge along the thin sides. Then either have them split themselves and/or the sound mechanism in half for twin swords or just keep them together and go Darth Maul style. If you go the twin blade route without spilting the sound mechanism, it can then be a music player on your belt, playing all your character's favorite battle tunes.
