Thread: Anyone for NAD?

So a totally innocent question in my honing video thread ("Is that stone a Nagura or a Nakayama") sent me on a truly wild chase. It sort of drove home that I did not, in fact, know what a Nagura was. So I decided to find out.

And boy, did I bite off a lot to chew. The cool thing is, it's lead to a lot of new depth of understanding in my search for True Ultimate Honing Powah!

The not-so-cool thing is, I might be developing Nagura Acquisition Disorder...
