CKF/Rotten Evolution 2.0 (dark Ti handle, ZircuTi pivot collar, Zirc backspacer, ZircuTi clip, M390 handrubbed satin). Your best mid-size pocket knife ever.

Evolution 2.0 designed by CKF partner Jonny Rotten of Rotten Design. The Evolution is a ergonomics-driven folder with a mid-size cleaver blade. A modified cleaver shape blade shape takes center stage on the Evolution. Blade 3.6 inches in length. The profile exhibits the squarish, wide, angular traits of a cleaver, but with some tweaks: namely a pronounced belly on the edge and a twice-dropped tip that still rises to an adequate point. There is no flipper tab on the Evolution; instead it is opened via thumb cutout. The blade steel is CKF’s go-to M390 stainless. The result is a definite visual change compared to recent CKF outings. Company Founder Mike Kulygin tells us that seeking out fresh styles is a core tenet of the CKF philosophy. “We’re always trying something new, or new styles,” he explains. “I would like to try lots of new designs from different people – who knows what will be the next.”
