Sonic Screwdriver

"It doesn't work on wood."

- The 11th Doctor on the Sonic Screwdriver.

The Sonic Screwdriver is a utility item used by the Doctor to perform maintenance, scan things, and point at things to look cool. It isn't actually a screwdriver.

It doesn't work on wood."Again, with the pointing!"

- The War Doctor on the 10th and 11th Doctors' pointing. No matter what that mean old War Doctor says, if you point the Sonic Screwdriver at something, you still look cool.
