If you modify that phrase to instead read:
"Maximum achievable sharpness with low to medium skill level"
Then you start to view individual steels for their real world characteristics as experienced by most people. Even with blades sporting more obtuse edge geometry. These steel types have the ability for easier sharpening.
So with this lens its easy to understand why many people gravitate and love steels like AS, White #1, or Blue #2.
The ability to sharpen your sticks to near a "razor sharp edge" or past is very desirable to most people.
Crappy Walmart, target, or big grocery chain stainless blades do not have these qualities.
Again, its important to understand steel as they actually function in the real world with use and sharpening... Not just as stats on a spec sheet.
I say this all with extensive real world R&D testing of things in real use vs. theoretical capabilities as theorized, hoped for, and told to us by those who engineered the items.
Real world always shows the truth of a product-- especially those meant for continual use and abuse.
