i think it's pretty much a sign of the times that even reasonable men on nostr don't even realise that scissors haven't been a commonly accessible tool until the renaissance and at best there was shears, crafted out of copper and steel
really, it took a lot of science to discover a way to make the razor
do you think they had razors, or at least, for very long, before they invented scissors? really?
if you can't make a knife sharp enough to shave your hair, sit right down now
