How to tell the grit of a sharpening stone & recommendation
I have a sharpening stone that I inherited from my Dad, and I have no idea what grit it is so I'm not sure if I should use it on my Christmas-gifted Masakagi Kiri Gyoto chef's knife. The only things I have to go on are the "Norton" stamp on one end and the letters "B6 IN XT6" on the box lid. It is definitely dual grit, as it has a dark side and a light side, but without knowing the grits, I'm loathe to use it. Do those markings mean anything to anyone here? If I cant sufficiently identify this, anyone have a recommendation for a good dual grit stone to keep this thing as razor sharp as it was when I got it?
