So, after hearing a bunch about shiro suitas from maruoyama, particularly how Milan likes them for kasumi, I decided to give one a go. What I really wanted to see was how it would vary from my other stone from maruo, my shiki uchi, as I can not find a ton of info on that stone online. Decided to have a little bit of fun with my yanick, both sides were prepped with chosera 800, then 3k, then the finishers.
Here are my findings...the shiro suita is much softer than the shiki uchi. It gives a much mistier kasumi, while the shiki uchi goes much darker, and interesting enough gives more detail on the wrought of my Yanick. I know shiki uchi is known for giving kind of a dark and heavy kasumi, but interesting to see how much detail still remains with it. The uchi is def a bit harder, while still being a soft stone. It's hard for me to define "fineness", but I would say the shiki is a bit finer, being able to draw out a little more detail. I still really enjoy the lighter misty kasumi of the shiro suita though. Finally I have a shot of my hakka suita, which is harder than both, and also a tad finer. It seems to be in the middle of the 3 stones, it has the detail of the shiki uchi, while being a little lighter like the shiro suita.
Please note this isn't going to be the same for every stone of these varieties of course, this is just a comparison between these examples.
This is a quick shot of the polish from the shiro suita:
