I just got a new zdp calypso jr. in the mail, and just like my previous one, its the sharpest knife I've ever had. It struck me that this knife, like almost all new pocketknives, has an unpolished bevel. Instead, it's sharpened on a belt I assume, and you can clearly see the scratch lines all along the edge in a single bevel (no micro bevel).
When using a sharpmaker though, its considered important to use the smooth stones to approach having a polished bevel. When using waterstones it's also considered very important to have a polished bevel.
So what gives? Does a polished bevel actually do anything? And if so, why is a new knife with an unpolished bevel so extremely sharp, and specifically how is this different than the edge achieved sharpening on the rough sharpmaker stones for example?
