 The Sonic Screwdriver |
Another favourite of the Doctors.
This device was introduced in the Web of Fear.
It allowed the Doctor to do anything he wished - he could open a door, or even destroy monsters.
It lasted up to the Fifth Doctors story - "The Visitation" as it was destroyed by one of the Teraleptils when he was captured
It made another appearance at the beginning of the TV Movie and is now in the new series with David Tennant/Billie Piper
