For carriers who want black styling on a proven CobraTec frame, the CobraTec Diablo 3.5-inch Black Automatic Knife delivers the Diablo line’s usual speed and fit (CobraTec part no. BLKDIABLOAUTO). It pairs a 3.5-inch blade in D2 tool steel with G-10 construction. Deployment is side-button automatic folder — the button fires the blade out the side of the handle rather than the front, and a sliding safety guards against accidental deployment. Between range days, work, and everyday tasks, it’s built to come out of the pocket ready.
