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. The Autonomy 2 s blade is full-flat ground from LC200N a nitrogen-enriched alloy that is extremely corrosion resistant. Its iconic leaf-shaped profile provides a keen, slightly curved cutting edge and an acute, utilitarian point. Like the original, the auto-opening blade is powered by a corrosion-resistant coil spring contained within a removable module. This patented feature allows the module and spring to be easily removed with the tool in Spyderco s spring replacement kit without disassembling the entire knife. To ensure convenient carry and immediate access, the Autonomy 2 includes a lanyard hole and a broad-based hourglass clip that is reversible for left or right-side tip-up carry.
