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.

Semi-Custom or Mid-Tech knives are knives produced by a process in which the designer has more direct--but not complete--involvement; parts of these knives may still have been made by others.
Frame Lock
Frame Lock
Developed by Chris Reeve, it functions like a liner lock but the lock is comprised of one of the handle scales. It's an extremely strong and easy to manipulate lock.
Pocket Clip

A tougher steel than S30V, it retains the excellent corrosive properties and ability to take an edge, but improves on the ability to hold that edge.

Pros: Blade Material, Overall Quality, Handle Feel, Weight, Handle Material, Blade Sharpness
Cons: None
Ok... So now I "GET IT"
Bought this a few weeks ago, never had hands on a Reeve knife before and the looks of the Sebenza just didn't do it for me. Once you feel this knife and open and close it a few times, you realize that this is a TOOL and meant to be used as one. Not something flashy to spruce up your pocket or to be fretted over if you scratch or ding it, no, this beast is meant to be used. It resides in my pocket with a Benchmark 940-1 (carbon handle) and an 810 Contego. Those both feel like children's toys in comparison. Kind of like the feel between a composite pistol like the Glock and the heft and feel of a good old 1911... Expensive? Yep.. Worth it, hell yes.

Great buy!
Great knife, but also really great customer service via Knifecenter, no problems in communication even though I live in Germany. The knife itself is built really well and I just can agree with the other reviews. If you are looking for a tactical folding knife that is designed and built without any flaw, you go very well with the Umnumzaan!
