Just thought I'd share some photos of two hones that I'm using a lot these days.
The first is a Nakayama Asagi that I got from Alex Gilmore. It doesn't have any stamps or other markings, but according to Alex it is a true Nakayama stone. It gives off a very white slurry when rubbed with a diamond stone and leaves a very nice, well-polished edge. It cuts very slowly.
The second stone is a nice Escher that I bought recently. The label was in horrible shape so I sealed it with polyurethane, which makes the stone much nicer to use now because I don't have to worry about damaging the label further. It cuts and finishes similar to other Eschers.
Thanks for looking, and enjoy!
