CRKUMNUMLEFT: Left Handed Umnumzaan

Chris Reeve Knives

In every sense of the definition, the Umnumzaan is a knife deserving respect. Developed from the multi-decade 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.

Chris Reeve had the working hand in mind with the tough build of the Umnumzaan, or Boss in Zulu. 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.

Typical of Chris Reeve Knives, 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 to reduce friction and to retain the fluorinated grease for longer lubrication thereby extending the life of the knife.

Ceramic Ball - The Integral Lock's Upgraded Interface

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.

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. Chris Reeve Knives appreciates their consent for Chris to use this adaptation of their concept.

Perfection!
The Umnumzaan has earned a reputation as one of the best pieces ever put out by CRK for a reason. It is amazing. The materials, the build quality, the action and Lockup, every single aspect of this piece screams quality. Out of the box the action is stiff as are most CRK models but after the initial "break-in" phase, it is buttery smooth. Definitely an heirloom quality piece while still being able to be a daily workhorse capable of handling just about any task thrown it's way. Overall, it is a definite winner. Great job!

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.
