Friendly advice: Don't put any money at risk on you figuring out the difference in a blind test... I could understand anyone here feeling confident that could tell a super-steel from a Chinese "mystery" steel after passing hundreds of blind tests... But the fact is none of you have the means to ever make any blind tests, or even have the slightest conception of how they are necessary to even begin to talk the way you do... And yet you speak as if you had made it through hundreds of blind tests and passed them with flying colors...
Let me put it this way, given the colossal amount of variables, and greater still potential for user-induced bias, not to mention the lack of microscopes to check the true condition of the edges you are comparing, or the materials they are cutting, what do you think would be a scientist's likely opinion of your pronouncements?
The best clue that you are clueless is this: Among the largest variable of any steel's edge holding ability is probably the basic cleanness of the edge material... Depending on source, you could have the same steel clean or dirty, and it will still pass basic industry standards (which you don't know what they are anyway): Yet NEVER on this forum have I seen the issue of steel cleanness discussed..
Why? Because none of you have the means to evaluate steel cleanliness to begin with, which requires an expensive lab, so the issue doesn't even exist for you... Yet for aircraft performance you can bet they do check aluminium for cleanness... That is why it is called "aircraft quality aluminium".
Because doing that boosts the costs to aeronautical levels, $1500 bolts and so on, I'll break shocking news to you: Your knives get basic industrial crud, but some industrial crud is cleaner than other, and you ignore it because you have no means to check for any of it anyway... That's how confident a scientist would be that you'd make it through a blind test...
