As a knife guy, this hurts to say, but you don't buy Case or Victorinox knives for the steel. Their steels are OKish, they're appropriate for the intended purpose of the knives and price point considering the build quality, but neither of them use steels that approach modern standbys in edge retention. Both of them have great geometry though, so as long as you aren't looking for a steel to geek out over you should be fine with what they offer.
Also with collecting Victorinox many of the devils are in the details, they are all variations on only a few frame sizes and a couple of designs with different tool and blade options, but they are also one of the most consistent manufacturers in the knife world. I don't believe I have ever encountered a Vic with an issue or flaw that seemed related to a production mistake or inconsistency, for a given frame they're nearly identical across years and layer counts.
