All About Pocket Knives features a price guide on its website for old Case pocket knives. The Case Knife Price Guide lists prices for utility knives made from 1920 to 2005, and the Case Classic Knife Price Guide lists prices for collectors' models produced from 1990 to 2005.
The Case Knife Price Guide has three search options: to search by entering pattern numbers in the search box, by using a drop-down menu with models and years manufactured, or by browsing links to pattern groups.
Prices in the guide are from 2011. Links to other knife-related information resources are listed under the Directory tab on the AAPK main page.
