We've seen sonic screwdrivers come and go over the years, but this is the first one sure to be exactly like the one the Doctor uses on the actual program (superpowers not included). It has the exact light and sound from the show, and extends the same way. It also has a UV light at one end and a pen nib at the other. The story goes like this: the prop made for the new series was small. Then this toy came out - it was bigger to accommodate the batteries - and the Dr. Who producers revamped the TV prop on a mold from this toy. So this Sonic Screwdriver is exactly the same size as the one Dr. Who uses on TV! $15. [GT]
