One of the most remarkable features of Spyderco's award-winning Autonomy automatic knife is its removable spring module. This patented feature allows the knife's kick spring to be serviced or replaced without having to disassemble the entire knife.

This kit contains all the parts and tools necessary to replace the coil kick spring of the orange Autonomy automatic knife (with or without button safety), including a module wrench, protective blade guard, Torx wrench, two replacement kick springs, thread-locking compound, a spare pivot screw, and step-by-step illustrated instructions.
