Enjoying knives, and collecting them are two similar hobbies. Another one is studying knives and learning more about them. Much can be learned from talking to old-timers, and reading knife books written by seasoned knife-lovers. Here are a few of my favorite knife books. My favorite is Advertising Cutlery. It can start you on your way to be an appraiser of collectable knives. All these books are in stock at the publisher, and will be shipped directly to you. It's good to have a set of knife books, if you want to be a serious pocket knife collector.
