This is my interpretation of the current series Sonic Screwdriver. It is a static prop. It is made of found hardware parts, mostly aluminum. The emitter is blue crystal. It is very heavy and has the feel of a real device.
Mostly out of found items like lamp finials and cabinet hardware. I have since changed it and like the look better. Just look at things a different way and piece them together to get a final piece that looks like what you had in mind. Go to Lowe's or Home Depot and look for things with an eye for detail towards a sonic screwdriver.
