This has probably been posted before, but I haven't been following all posts and have never seen it mentioned before. A booklet titled: 1895-Essay-on-Barbers-Razors-Razor-Hones-Razor-Stropes-Razor-Honing
This guy was clearly getting some advertising dollars for this book. He's throwing a lot of marketing around as "expert" opinion. It's still pretty cool. Also anyone catch the bit where he said to soak strops in Urine? Yeah Id pass....But....a Shark skin strop is now on my want list lol
