This Gillette Tech razor was made for about 30 years in various countries using various materials, as far as we can tell there are no set rules on how, who, and where, what materials were used, and with what models, so I'll simply judge by weight and visual observation and give as accurate a description as I can.
This Tech (no date code) is USA made and has gold over nickel plating with quite a bit of plate loss in several places, that being said it is corrosion free and ready to deliver service for another 60 years!
The razors weighs 60 grams and stand 82 mm high.
