70 razor and shaving patents . A meandering look at the history of shaving, as seen through patents from the last century and a half. Somewhat serious, somewhat humorous, with quite a bit of snark. The book explores a wide range of ideas ranging from electrically heated razors to plug into the light fixtures, magnetic pseudoscience, and of course the ever present vibrating razors. And you’ll find a few sensible razors that were the right idea at the wrong time in there too.
What I appreciate the most is the author’s commentary. He points out the most interesting aspects of the patent in a couple of short paragraphs. This isn’t always obvious from the patent drawing itself, so the author has done the work of reading through the patent and describing the vision and features of the invention.Dennis, review on Amazon
