Not a fan of auto knives
I don't think auto knives are as good as a one hand operation non spring activated knife. I have better grip and control over the knife when I don't have to loosen my grip to push a button. I prefer a good quality knife that I can open with one hand but has a solid lock that moves in front of the blade, not a little notch on the back of it. I really don't want the lock to fail if I need it. My favorite is a Benchmade stryker with a half serrated blade. It opens with very little effort once you get use to swinging it correctly and I don't have to worry about a spring failing, or a legal problem. If auto knives were perfectly legal everywhere, I would still opt for a manual opening knife. There are many high quality knives made similar to the one I posted here, but the design is solid.
