The Autonomy was developed to meet 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.

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.

Perfect Missing Item For U.S. Military Collection
Michael S.
I have wanted one of these to go in my U.S. Military collection for a very long time. I was told that the U.S. Coast Guard had first priority and none would be sold until that first contract was filled. I think I have waited several years to get one. It was well worth the wait and lives up to the hype.

This automatic has many unique features not found on other knives. The salt water resistant H1 steel is only one of them. The large oversized firing button is another, but not just because it is easily accessible.

This knife is also designed so the the back-plate on the button can be removed to replace a broken spring without disassembling anything else. It makes it field repairable vs only doing it at home due to the small Torx screws and parts that can fall out and get lost unless working on a well lit table. The action is very strong and what you would expect coming from anything Spyderco. No blade play is present and it locks up like a bank vault. Although originally developed for the U.S. Coast Guard, it fits very well in any U.S. Marines personal collection. This is one cool knife for sure!

Unique auto

It's just so different than any other auto I own. You just have to buy one to understand. I bought mine for collectible reasons but It's built like a tank. Made for very hard use.
Very Sweet

Very well made, great snap, super tight lock up. Made to fit every need from EDC to tactical. As always there is also spydeco's famous serrated blade.This is a knife built to handle any need. I would have gave it 6 stars if it came with a sheath. Very Awesome....
Buy one before they're sold out
Clifford S.
This is a big Spyderco automatic, Endura sized, wth a great oversized button. The skeleton pocket clip is tip up only, right or left hand carry.Beautiful, all business looking knife. Get one before they're gone.
Best Knife I've Ever Owned!!
Josh L.
This knife is by far the best knife I've ever owned! First off, this knife is so sharp! Plus, the button is very easy to push with gloves on. I work construction, and have yet to find a more practical knife. I hope this knife is never discontinued.
Ninja knife
Spyderco does it again! Love this knife! Excellent automatic knife. The action is super fast and smooth. The blade comes out with authority. The deployment button is extra large and works well with gloved hands. The detent has a nice secure snap. Super sharp. Made out of H1 Steel which is perfect for salt water environments. The grip/scales G10. Fits well in the pocket. Not too heavy. Made in the USA. Overall 5 Stars. BladeHQ shipped it out fast!
