I'm curious about this stuff. Clearly you guys are using the nagura-type honing on a hard, high grit finisher. And equally clearly, this approach dishes the finisher so that you need to lap it, is that right? Or is this simply that people don't like nagura scratches on the surface of the finisher and so lap it more often?

I haven't "lapped" my stones since their first use, so I wouldn't say this method causes significant dishing.
