I just wondered as many of us here at the forum think it's a great steel. I wondered if anyone knows why they stopped using it?
I know the SS Dragonfly still is sold with an ATS-55 blade but that's all I know of that is.
My ATS-55 Delica out cuts the VG-10 Delica and also the S30V on the Native I had. It also holds an edge longer and is easier to sharpen.
If anyone knows why Spyderco stopped using this steel or if it will ever be used again please feel free to chime in.
