This is an outstanding reference work on safety razors, extensively illustrated with color photos. The author obviously did an exhaustive amount of work to compile this. A great benefit to the collector community.

Great reference book with company history, patents, date codes, adverts and tons of illustrations and photos on every page. It will help you date any collectables you find and inspire you to search and collect things you didn't previously know existed. ... it’s razor porn if ever there was.

Directory information a lot. But it is mostly superficial. Although the author very great respect. In short, I do not regret that bought.

A large file at about 260 megabytes. The resolution of the photos is higher than in the print edition which I also have. I just wish the information on the individual entries was more complete. Still a monumental work that must have taken thousands of hours to research and write. After download back it up as you have a limited time to download it. Once downloaded I transferred copies to multiple thumb drives for backup.
