Zeasor--
My link above is to The Razor Edge Book Of Sharpening. I haven't read every sharpening book out there, or tried every sharpening method, but I tried quite a few. Over time, I was getting discouraged and frustrated with not getting the knife edges I wanted by freehand sharpening. When I read this book and used their hones (they also sell sharpening guides, which I don't use) I finally got the edges I wanted, and stopped looking.
I also read where the book is "old", as if sharpening theory and methods that work change as fast as computers, media players, and other electronics. People have been sharpening cutting edges for tens of thousands of years. This isn't exactly new technology that needs to be updated every few days. If the edges I'm getting are "wrong" because the book is "old", then in his case I'm very happy to be wrong.
I highly recommend this book.
