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.
