The Rock Star recipe creates stones that are slightly harder and finer than the Kuromaku stones. It’s a small difference and it will come down to user preference as to whether you prefer it. For those who know the Shapton Glass stones, Shapton considers the Rock Star to be a thicker version of the Glass Stones without a glass backing.
