Chris Reeve Knives introduces the Umnumzaan, a new milestone in folding knives

Chris Reeve Knives describes this item as follows:

In every sense of the definition, 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.

A ceramic ball creates the interface between the blade locking surface and the integral locking arm surface. The ball doubles to drop into a detent on the blade to ensure the blade does not open accidentally.

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 reduce friction and double to retain the fluorinated grease for longer lubrication thereby extending the life of the knife.

The thumb lug doubles as the stop pin, ensuring a solid lockup. Around the lug is a polyurethane o-ring that acts as a shock absorber to cushion the impact of the lug against the handle. Never wishing to copy other designs without giving credit, Grant and Gavin Hawk originated the shock absorber concept in one of their many innovative designs. We appreciate their consent for Chris to use this adaptation of their concept.

The Cream of the Crop
Yes, it's expensive, but if you are a knife user/nut, you will have to experience it once in your lifetime. This is my first, a left-handed Umnumzaan, and I absolutely love it. Not only the superb fit and finish, but when you cut things it becomes apparent that the quality is top notch. The only problem: I wish I bought it sooner.
