SHAPTON Glass Stone High Carbon 6000 grit, 2.45 micron 210mmX70mmX10mm(stone 5mm/glass 5m) for Fine Finishing Whetstone for High Carbon Cooking Knife
There is two different SHAPTON Glass Stone 6000 Grit. One is regular hard type(white color) that is called High Rockwell Series (HR). The other is softer version (light gray color) that is called High Carbon Series (HC). High Carbon Series is little bit cost more than High Rockwell Series, but it is excellent for sharpening high carbon edge knife and single bevel edge flat side that is called Uraoshi by used and proved professional. We feel HC much softer than HR, but it does not mean wear faster. I have used it a lot for three years, but I think I can use it more than another three years.
I really love to use it as razor finishing hone too. I have also use #16000, but #6000HC gets better result for final sharpening for razor blade.
