ATS-55, the offspring of its parent steel, ATS-34, which was the popular high-carbide Hitachi-made stainless steel of the 1990s (which followed the very similar American steel, 154CM). To create ATS-55, the molybdenum from ATS-34 was removed, making it a non-high speed steel (certainly not needed in a knife blade), with the side benefit of being more economical to produce. ATS-55 is reported to have better edge holding and toughness than its parent, ATS-34. In Spyderco knives, ATS-55 was replaced by VG-10 [year?]. Rumored to be a difficult steel to heat treat properly. Found in Spyderco's recently discontinued Cricket and Goddard. Taken from the spyderco.com forums and reprinted with kind permission from author [1]
