Chris Reeve’s Umnumzaan In every sense of the definition, the Umnumzaan is a knife deserving respect. Developed from the 20+ year heritage of the Sebenza, this bold, innovative folding knife is one to be reckoned with for its inventive design features and ability to get the job done. Typical of CRK, the pivot strength is more robust than other folders. The large pivot screw and pin are supported by large thrust washers. These perforated phosphor bronze washers are designed reduce friction and to retain the fluorinated grease for longer lubrication thereby extending the life of the knife. The Umnumzaan was the first introduction of the Ceramic Ball-End Integral Lock mechanism. Sturdy and over-built, the Umnumzaan brings the strength of a fixed blade straight to your pocket. With a sandblasted crosshatched grip and a wide lock bar, the Umnumzaan is meant for a non-slip grip and action for a large or gloved hand.
