My VG-10 experience(6-7 spydies I think) so far, is that it holds an edge about 30% longer than ats-55 before it's butterknife dull. As I never let them get to that point(had to once just to see how long it took), thats not a concern. If you are comparing PE on them, the vg takes a finer edge, with a smaller grain structure then ATS-55. Plan to shave with it?
ATS-55(about 9-10 so far) takes a sweet edge, is soft enough to allow manipulation(convexes nicely, or thins nicely) and I have yet to have a problem with rust(and I eat off it and cook with it, as well as use it at work). My ss pe 'fly has been wet a *few* times, has gone through the laundry once(came out smelling spring fresh, but the LSA 0-158 killed that smell}, and stayed under my shirt in a neck rig when I was sick in early august(21hrs in bed) and the sweat did nothing to it.
