Query: A Classic Work Which Deserves Its Status

This book is a true guide for a wide range of collectors, and would be collectors. I am impressed with its layout, which facilitates the very dense amount of knowledge being offered by Mr. Levine. Seldom have I seen a book of over 500 pages that actually seems to convey more information than its page count would suggest.In other words, if you are really interested in knives at all you ought to own this well crafted book. Why not all 5 stars? My only real criticisms are that some of the graphics should be better and the paper used is poor, (perhaps these two items are related.Anyway, great book, buy it, you will never regret it.
