SJ-250 Japanese Waterstone | which standard is used to specify the grit?

What standards does Tormek use when specifying the grain of Japanese waterstone? Is it the JIS or FEPA? Because if the grain 4000 FEPA is given, then it corresponds to the 16000 water stones according to JIS?

  • Hej Eduard

    The Japanese Waterstone is specified to JIS and all our other stones to FEPA.
    I hope this answers your question.
