Dr Who - The Twelfth Doctor's Second Sonic Screwdriver
The Doctor's multi purpose tool features numerous settings. It can open most locks, detect all manner of deadly rays, read bio-signs and can generate sonic waves of great power. It does however have a bit of trouble affecting wood...
The Doctor has carried many Sonic Screwdrivers of various designs throughout his lifetimes, ranging from a simple silver coloured tube to more complex illuminated and articulated versions. For a while he eschewed the classic hand held screwdriver in favour of a pair of 'hands free' sonic shades, but now he's gone back to using a more conventional device.
This latest revision is brighter and more complex than before. Time will tell if it gets the Doctor into more trouble that it helps him out of.
