Spyderco Autonomy Auto Folding Knife 3.65" H-1 Black Serrated Blade G10 Handles - C165GSBBK

The Autonomy was developed based on the demanding mission requirements of the U.S. Coast Guard's rescue swimmers. The SpyderEdge rescue-style blade is the first American-made knife to be ground from H-1 steel, a nitrogen-based steel that is completely immune to saltwater corrosion. Its automatic opening is powered by a coil spring nested within a unique removable shroud that allows the spring to be serviced without disassembling the entire knife. An oversized firing button enables quick indexing by tactile sense—even while wearing gloves or suffering diminished dexterity due to cold. 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 black G-10 scales, a non-reflective black coating on the blade and all hardware, and a secondary safety to prevent unintentional operation of the opening button.
