My only experience with automatics was when I was a kid in the '70s I carried 2 POS switchblades for self-defense, a medium-sized one and a very large one, both with stiletto blades.
Thankfully I never needed one in either self-defense nor any other life-saving emergency situation (mine or others). Besides the blades being as sharp as butterknives, the larger one one day stuck closed, and thereafter I could never even force it back open. The smaller one still works, but has considerable blade play...probably from a combination of poor quality to start with, plus the constant force of being snapped open.
I know there are MUCH higher-quality offerings in automatics now, but the same principle IMO still applies: If there are more things to go wrong with something, they will. As tools, there is no advantage an automatic has over any manual one-hand folder, or in the wilderness a fixed blade.
