In every sense of the definition, Umnumzaan (pronounced um-num-zahn) 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.

The newest rendition of the famous Umnumzaan knife is crafted with high-performance CPM MagnaCut which provides outstanding toughness, rust resistance, and edge-holding capabilities with a heat treat hardness of 61-62 HRC. 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 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 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.

I wanted a really well built knife that was made in the USA for tactical/EDC and this Umnumzaan fits the bill perfectly. The knife is Great and so is the customer service with OGK.

I have had my Umnumzaan for several months now and it has stellar performance in all ways ! The quality is top notch and the titanium handle and S35VN stainless steel blade is superb. Weighing in at only 5 ounces it is great for EDC. The 3.675" blade opens easily with the thumb stud and closes very securely. The titanium has is comfortable, attractive and ergonomic. Smooth action, solid feel, and attractive design. Oso Grande's shipping was fast! Don't hesitate to buy this knife because of the price. you get what you pay for!

I recently purchased the Cold Steel Norse hawk, Spike Hawk and the Bearded Axe. I found these to be excellent products, well made with great fit and finish. Oso Grande Knives service was equally good. Looking forward to doing business with them in the future.
