The Dremel
This was a bit of kit that I've always wanted! Basically a mini hand help drill that you can put lots of attachments on to do close, or fine work. The idea behind the purchase was to use it mainly as a cutting tool, to precision cut the typewriter keys in order to make the keys for the keyboard.
I bought mine from a Dremel dealer in the UK, however there are many other makes and suppliers that sell the same sort of thing for less if that's what you want!
