Long time collectors often refer to Case knives from the 1920's and 1930's as "Circle C" knives, a term derived from the famous Case Tested tang stamp of that period, which featured the "Long Tail C" Case Tested logo. The legend of Circle C lives on with Circle C family of knives. Ten of our most popular patterns are offered, each with Tru-Sharp™ surgical steel blades and standard jigged Kentucky Bluegrass bone handles precisely routed and inlaid with the nickel silver Circle C shield.
