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.
