VERY handy for noobs to identify some razors and companies but isn't easily read (for me anyway) and isn't exhaustive. A damned sight better than I could have done, though.

I should have bought this 5 years ago...

An excellent resource for all safety razors replete with color photographs. The actual book only has black and white images so the digital download really helps in identification

An outstanding reference book on safety razors, it is a 'must to have book' for every collector!
