No, the First Doctor did not have a sonic screwdriver. The sonic screwdriver was first introduced as a tool for the Second Doctor in the classic series before becoming a staple for all subsequent Doctors.
it is cool
because the fifth doctor lost it
Try Argos or eBay there good for stuff like that
Yes the 1-8 doctors used lots of different tools such as the sonic chisel, the sonic hammer and of course; the sonic Philips head.
No. Patrick Troughton, the second doctor, was the first to use the sonic screwdriver, and even then, it was a part of the TARDIS repair kit. The screwdriver made appearances in other Doctor Who episodes with later doctors, but didn't become the Doctor's tool of choice until the series rebooted in 2005.
You can't, the sonic screwdriver isn't an actual screwdriver. It's a sonic alien one. ;) On the show, the sonic screwdriver is basically a torch and makes no sound, they add the sound in later while editing.
That's rather a relative question. The 11th Doctor's screwdriver seems to do the most, however it can be argued that has he relies on it much more heavily than previous doctors, it is less of a help and more of a crutch.
