UndercoverMan saidWhy do you think beards and moustaches were so popular in the good old days?
There was a reason the safety razor was invented.
The "good old days" weren't always so good.
And Mountain Men shave with a hunting knife, when they shave at all. There were times when I shaved with an Army bayonet in the field. Not pretty, lots of nicks and tissue paper on my face.
I don't understand the point here. You should shave with the available technology that works best for you, and not according to John Wayne macho cultural expectations or myths.
Straight razors were the best available in the 1800s. These are not the 1800s. Today's commercial razors, even disposables, are sharper than any straight razor ever was.
Right now my partner isn't allowed to use any blade, because he's post-op on blood thinners, lest he get a cut, so I shave him with an electric. And electrics are fine for most guys, too, shave close enough for most situations. This is the 21st Century, not the 19th.
