This video has been quite popular among Italian wet shavers. It also proves - once again - old barbers have always stropped their razors with hand palm. And this is what Mastro Livi keeps on telling when he talks about the old times when all of his barber clients, besides giving him their razor for fixing and honing (Mastro Livi is in this business since 1955, carrying on the heritage of six generations), they all stropped straight razors with hand palms.
I too remember my grand father doing the same and I am doing this as well since the day I started using a straight razor. It works, it works very, very well.
