Spyderco's award-winning Autonomy literally revolutionized automatic knife design. Developed to meet the demanding mission needs of U.S. Coast Guard rescue swimmers, it features a number of unique engineering advancements, including an oversized firing button, integral button spring, and a patented kick spring module that allows easy spring replacement without disassembling the knife. All these features complement the knife's highly evolved design and rustproof construction to make it impervious to the elements.

The original Autonomy, designed specifically for carry in a dedicated pouch on a rescue swimmer's vest, featured high-visibility orange G10 scales, but no button safety or clip. To adapt the knife to the needs of the rest of the tactical community, Spyderco modified its design to include a button safety, reversible wire clip, black G10 scales, and a non-reflective black coating on all metal parts.

Based on popular demand, Spyderco is proud to introduce a third version of the Autonomy that walks the line between the first two. Like the original version, it boasts a satin-finished H-1 blade and bright orange handles; however, it also includes a firing button safety and a reversible wire clip to make it suitable for pocket carry. The button passes through both stainless steel handle liners, stabilizing it and increasing the blade's lock strength. The button's spring is also integral to the stainless steel liner, providing increased tension and eliminating any cavities within the handle that could retain water. The knife's open construction allows it to be easily cleaned and dried, making it the ideal tool for waterborne rescue operations. Winner of the prestigious "Most Innovative American Design" award at the 2012 Blade Show and International Cutlery Fair, the Autonomy features orange G-10 scales, a satin finish on the blade and all hardware, and a secondary safety to prevent unintentional operation of the opening button. For service personnel who don't require a tactical black finish on their knives, this version of the Autonomy is truly the best of both worlds.
