Exactly. Hence you are never going to get a night and day difference between steels that all perform at well above average. S30V nor XHP deserve to be anywhere near the level of "low end" just because there is a buffet of fancy steel compositions out there now days. There are too many factors that play a part in edge holding. If any of us here got given S30, M390 and XHP on random unmarked blades i bet you a million dollars none of us would notice a difference in real world use. Whoever says they can, well...you just keep on thinking that

I primarily carry M390 on my contego, S30 on a millie and XHP on a CS recon 1, and i can tell you at 18-20 degrees per side you could
not tell them apart if the blades had no markings. That's on wood, cardboard, drywall, thick plastic and cutting heavy duty electrical wires on a very frequent basis.
