Spyderco Autonomy Automatic Knife 3 75 Black Serr C 165 GSBBK

The Autonomy was developed to meet demanding mission requirements of the U.S. Coast Guards 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 senseeven while wearing gloves or suffering diminished dexterity due to cold. The button passes through both stainless steel handle liners, stabilizing it and increasing the blades lock strength. The buttons spring is also integral to the stainless steel liner, providing increased tension and eliminating any cavities within the handle that could retain water. The knifes open construction allows it to be easily cleaned and dried, making it the ideal tool for waterborne rescue operations. 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. Winner of the prestigious "Most Innovative American Design" award at the 2012 Blade Show.
