The Autonomy 2 takes all the groundbreaking features of the original Autonomy automatic knife, which was developed to meet the demanding needs of U.S. Coast Guard rescue swimmers, and incorporates them into a design optimized for utilitarian use. Its ergonomic, open-backed handle is built with full stainless steel liners flanked by textured G-10 scales. The easily indexed oversized firing button includes a sliding safety to prevent unintentional activation and extends through the opposite-side liner to maximize lock strength.
