The Case Cheetah knife, or 11 1/2″ pattern, has been around since the pre – 1920 W.R. Case & Sons, Bradford, PA days and is highly sought after by collectors. The Cheetah name was first used around 1970. Most measure 4 3/8″ closed and feature a swing guard and a lock for the single clip point blade.
The swing guard was added to the Case Cheetah knife during the Tested XX era. Handle materials feature genuine stag, bone and the rare green bone as well. Check out my vintage Case XX knives page.
