Absolutely nothing, but....

What's wrong with laughing at a comment you find hilariously funny?

Another reason I'm not into shiny blades (mostly the ones with a mirror finish) is that I'd be afraid to use it. Such surfaces are beautiful and almost artistic. With the shiny knives I've owned, I would cringe every time I seen a scratch on the blade. Each time I used it, my eyes would go straight to that mark. I wouldn't use the knife to its full potential simply because I was avoiding putting a blemish on it. Also, any time I used my mirror finished knife, I could be seen obsessively polishing it back to its original luster.

With non-reflective finishes or coatings, I seem to be less concerned about blemishes on the blade. They just kind of add to its charm, kind of like a well used Jeep. Even if it's a coated blade, I'm not concerned about losing that coating over time. That's not to say that I don't take good care of my knives either. I still keep them clean, sharp, and oiled.
