The only way that we've found is to have a metallurgical testing lab do a chemical analysis. Expensive, but accurate.

That isn't entirely true. A PMI, with a quality analyzer, can give you a pretty accurate breakdown of the element content. If those particular alloys are in the library, the database, it will give you a match. If it is not, the data can be compared to known formulas. Every steel producer provides those. In addition, using a known and trusted source can provide further evidence. Spyderco's S35VN looks pretty much like everyone's S35VN. The same steel doesn't mean it is the same quality. I recently Rockwelled a fairly known, cheap knife that was supposedly S35VN. It was...at 52.5 HRC!
The biggest reason I started doing tests for reviewers, was to find those dishonest companies and out them. Not just the steel but Rockwell, too. That is all I can do. Other's are doing the cut tests, trying to put some clarity on heat treat quality. I work pretty hard for my money, and I know most do. I'm trying to make sure people are getting what they pay for. As for what they cost, I don't care. The consumers have to decide that for themselves.
