A grindstone with diamond particles fixed to the metal surface by plating. |
A grinding stone made by combining diamond particles with a binder and sintering them under high temperature and pressure. |

| Good |
・The particles stick sharply to the blade, providing a high abrasive power. |
Compared to electroplating, the scratches are shallow and can be easily removed. |

| Bad |
Diamond particles are simply attached using a plating process, so they don't last very long. |
・Abrasive power is slightly weaker than electroplated type. |
