The Best on the Market
I've owned dozens of automatic knives of different makes and models from Benchmade, Microtech, and Spyderco. I also own the Spyderco Tusk, SpydieChef, and now the Autonomy with LC200N steel. The design of the Spyderco Autonomy makes it the most advanced and durable on the market. It's heavy-duty lock and the ability for the owner to replace coil springs is exclusive of the model. A spring kit is available which contains the special tool to disassemble the spring module. The LC200N blade steel is remarkably corrosion-proof, yet it still holds an excellent edge and is easy to sharpen. The steel is so impressive, it represents a revolution in knife blade steel. The edge retention is better than the corrosion-resistant H-1 steel used on the Autonomy USCG knife. The configuration of the Autonomy 2 is very close to that of the Paramilitary 2 (PM2) which is perhaps the most popular knife in the Spyderco line up. The advantage of the Autonomy folder is that the automatic mechanism locks the blade in the closed or open position. Although the PM2 is perfectly safe to be carried in the pocket, having the ability to lock the knife closed may be something you find value in. Summary: This knife is the best automatic knife from a mechanical engineering perspective, and has revolutionary blade steel that's impervious to rust and corrosion. The final attribute is that the configuration of the handle and blade shape are very close to the popular Paramilitary 2, which is very popular in the Spyderco line of choices.
