Neal Punchard is a staff writer for KNIFE Magazine, and I'm a long-time Boker collector. In addition to the website, you can pick one up on eBay and a few used offerings are on Amazon. You can also pick up a copy of the German language version on Amazon. It is hardback. We spent literally over a decade researching, and two years writing this book. I hope you continue to find it a useful research tool. It's wonderful to meet another Boker knife collector! -Ricky Ray
