A few months back I picked up a nice, very very hard full sized Kiita awasedo. Recently, I have been playing around with a Tsushima black nagura I have had for quite some time thats been lying around the house. Needless to say, I like the results Im getting. Not anything fast, but It is steady with sort of a linear slurry breakdown. The clay or mud binder seems to have a little diffrent quality to it that I like a lot. I am thinking about picking up a full sized stone and wanted to know from those with more experience and or opinions. My guess would be that Im getting more breakdown on my awasedos than I would using the tsushima full size stone. But maybe Im wrong and that stone would bring something else to the table Im missing?
