I wonder how many people actually bothered connecting the earth lead on the 2 to 3 pin adaptors supplied with these. In 1957 I imagine there would be a good proportion of 2 pin sockets in use. Of course if the 2 - 3 pin adaptor is lost, one reaches for the pliers, and miraculously the plug now fits.
Hands wrapped tightly around metal cased power tools gives me the creeps.
Does double insulated construction apply in the U.S these days? While obviously modern power tools sold in the U.S are plastic cased like the rest of the world, do they have the 'square within a square' symbol on them to indicate this, or is it only in the 220-240V countries?
