According to Takeda's literature, his handheld sharpening stone are WA1200 and C800. Presumably that is the grit rating? Or can someone help decipher those numbers?
I am in the process to find new sharpening stone. I can produce an edge that slices nicely through printer papers most of the time with My good old el cheapo stone from local market. But it feels rough when I slice newspaper; either my knife doesnt bite well or just not sharp enough. Any suggestions?
