The Spyderco C165GSBBK Autonomy Automatic Knife H-1 Salt Black Serrated Blade. The Autonomy was developed to meet demanding mission requirements of the U.S. Coast Guard’s rescue swimmers. The Spyderco Edge rescue-style blade is American-made knife 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.
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.
