It is a very good book. Mind you, I do not have anything as old as what the book focuses on as I have little interest in the very vintage knives. With that said, I learned a lot just looking at the pictures, and I am sure, once I start to read the book, I will learn a lot more. I did find it really neat that SakWiki and Multitool.org got kudos at the very back of the book. That was very nice and cool. That and it is always nice to support a fellow Canadian.
