I had this made about 10 years ago. It is 100% custom piece. It's just a monster of a saber. It about 13". All s/s steel and anodized aluminum. Delrin grips. This is packed with goodies inside. It has a high power led to light the blade and plasma vents. In the pommel there is the soundboard which activated with a trigger. I went with to 2 switch boxes. Each have 5 independent firing lights. In between the barrel led and the wired switch boxes, there is a counter-weighted motor that when pressed, makes the prop quiver in your grip. There is a spring loaded trigger that fires up the motor. The farther you push the trigger the faster the motor spins. It's really amazing piece.
I'll pull some pics and post.
