Blades have always come with some sort of “profile” on them. Whether or not they matched from the factory, or players did anything to maintain or update that profile is dependent on that player.
On this site you have a bunch of nerds who overthink everything and are insistent on all the latest technology an trying new stuff. On the other hand, you have people skating on skates from 1997 with steel you can barely see, and they are still good players.
Lots of people, myself included, would advocate that it’s worth profiling your steel and spending the time and money to maintain it. But, if you’ve never thought about it and you don’t feel like you’re missing anything, maybe that time and money is better spent elsewhere.
That’s a total non-answer, haha, but I do think we tend to overcomplicate things sometimes.
