Vintage Case pocket knives are far and away the most collected traditional pocket knife.  Ask any collector and they will be familiar with the distinctive jigged bone pattern and Case oval shield.  From its humble beginnings in the roots of JBF Champlin & Sons in the 1880’s, the Case family tree would branch out far and wide.  There are a wide variety of highly collected patterns (Congress, Stockman, etc.) as well as beautiful handle materials that have stood the test of time.  I appreciate any traffic from these links as I earn commission when an item is purchased, at no extra cost to you.
