The Chris Reeve Umnumzaan – Tanto 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 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. This Umnumzaan tanto model features a CPM-S35VN stainless steel tanto blade with a stonewash finish. The blasted finish titanium handles have great ergonomics and feel great in the hand.
CPM-S35VN Steel: CPM-S35VN is a quality stainless steel that is part of Crucible Industries’ “SxxV series”. “CPM” identifies the steel as having been made through Crucible Industries’ CPM process, offering an improved outcome over that of conventional melting practices. The letters “S,” “V,” and “N” refer to the terms “stainless,” vanadium,” and “niobium,” respectively. The number thirty-five has no significance other than to differentiate between S30V steel. Despite the high level of toughness in this steel, which usually diminishes a steel’s wear resistance, this steel does not lose out on a superior resistance to wear and chipping. CPM-S35VN steel is incredibly hard, and a high quality steel that offers superior dimensional stability, grindability, and toughness that together make this a top grade steel.
