I have read the short book "sharp practice" by Anders Larsen. The book was a history of shaving and also a good manual on different techniques for shaving. Some of the sections on the history of shaving looked like they were copied of the Internet, but he told some good stories. I liked one where he fell asleep in a barber's chair, and the barber shaved all his hair off.
The book was particularly good for learning how to use a cut throat razor. The reality is that I don't have time to properly learn how to use one. Also, it would be a problem to take a cut throat razor in my hand luggage. Still I used to like looking at the cut throat razors in the shops around Manchester Piccadilly railway station.
I would look so cool shaving with a cut throat razor - much more of a man than now, when I shave with a wimpy Gillette Fusion. And I would save money, given the high cost of the fusion blades.
