I am now 73 years of age, and it is quite a number of years since I practiced Toolmaking. Amongst other tasks, I used to, in the `old` days, engrave, tediously, by hand & hand held `HSS graving tools,` (not hi-speed dentist type, air-driven type cutting tools) to make the tool steel dies used in the manufacture of Minted Currency Coins, for the Australian Mint & Internationally. My hands are now somewhat `shaky` and, I no longer possess my `high/variable` Lietz`Magnifiying spectacles that was used in the dim dark past for this type of work. So, after all that, I simply `wrote` the letters by hand, using a `water-proof` 0.1 mm pen, as used for writing on copy CD`s & DVD`s.
