It's one of the better stainless steels, used by Jerry before INFI was found.. It's tough (not sr77 tough!) can take rockwell 61 and is good all round stuff. Great for smaller sharp slicer knives. sr77 or INFI are probably better for big 'uns! (Due to ATS34's lesser impact toughness- due to the chrome content perhaps?)

JYD #3 Poor, but still dreaming of a sage and black SOD CG...
