What every doctor needs...

A sonic screwdriver!

Made from machined aluminium, this is a shiny replica of the prop used by Tom Baker during his tenure as the doctor.

This was made with several built-in functions. For example, the screwdriver slides inside itself to activate at the handle...

And also at the top (a feature not seen on the prop but I just wanted it to do more!)...

I have made it portable for carrying around with a 'twist to lock' feature that holds it closed...

And finally the head is removeable to keep it protected during transport, and to copy the original prop...
