I do have one comment on a theme I see here, “we” meaning people who enjoy this as a hobby didn’t invent the multiple pass shave as has been stated elsewhere, my dad taught me to do 2 passes and it seems almost everyone else is the same, maybe 1 pass and touch ups or 2 passes even some 3. But I think this idea that the all the old timers only did one pass and done has been debunked. I do think we invented the idea of a 30 minute luxury shave at home though. My dad can do two passes in about 5 minutes flat, I spend that much time just getting the water the right temperature…..
