Nothing wrong with it. Used to be my "go to" steel for stainless. I like CPM 154 better, but nothing wrong with ATS-34. Far as that goes, nothing wrong with any knife steel for an EDC folder, provided the heat treat is spot on. More arguments and blame are laid at one steel's type or the other when it should be the heat treat. In the real world there is not a huge difference in performance, some people can notice a difference, but a lot won't. More difference will be noticed between a good heat treat and a poor heat treat, far more than two different steels with excellent heat treats.
