I try to keep my tools and other stuff pristine, a throw back to early days with no money to buy things, and a Tech in Training being taught he had to keep issued tools as good as new else I have to pay for replacsments. In fact I still have tools issued in 1969.

P.S - under no circumstances are you to tell me that book is a coloured version.
I know of only one EDM book that is printed in colour ?.........yes you know who you are.......?.
