Spyderco's page says that it is ATS-55 steel, but I was under the impression that the new model lightweight delica AND endura both had vg-10 blades. spyderco.com only lists the delica as having vg-10 though.
as for other stores online, I have seen them labeled as aus-6, ats-55, and vg-10 depending on where you look.
also: The stainless steel endura is thinner than the FRN endura correct? does the frn's handle have much flex to it? my ladybug has quite a bit of give when you squeeze the handle but I always chalked this up to it being so small.
thanks,
