SOTD - October 2021

[Twelvefret]

I used the gold GEM Push Button with a near dozen use PTFE blade.

First time I have noticed the push button was marketed toward men with tough beards. Interesting.

Perhaps it is a change from avoiding the five o'clock shadow since that would indicate performance. 

So, this model being introduced around the same time, late 1950's, as an unmentionable dual edge had red, blue, and bare TTO knobs the later an adjustable. Apparently,  the race was on to provide a  more individual performance razor.
