The Geronimo is Kunwu's full size expression of the Verta Lock, the proprietary mechanism the brand built to stand beside its frame lock and XT Lock designs. It runs 8.3 inches overall around a broad 3.58 inch Vanax blade with 3.38 inches of working edge, and like everything in the Kunwu catalog, it rides on a 3D machined titanium clip.
The family splits along handle material. Diamond textured TC4 titanium in beadblast grey pairs with a satin Vanax blade for the classic Kunwu look, while the forged marble carbon fiber build wears a DLC blade and trims the weight from 5.32 ounces to a startling 3.77. The same Verta Lock architecture drives the Kunwu Gringo family for anyone shopping the mechanism at a different size.
Every Geronimo runs Uddeholm Vanax SuperClean hardened to 60 to 61 HRC, the nitrogen alloyed Swedish stainless that anchors Kunwu's steel program with corrosion resistance approaching immunity and a fine grained edge that holds its bite. Our guide to every major knife steel shows why Vanax earns its premium.
