Hand sharpening under 200 grit or less requires a more powerful cutting speed. This stone can be used when you feel that the speed has slowed down. In the Metate process, which involves making the sharpening stone surface rougher to revive abrasiveness, this stone can effectively restore cutting speed.
We recommend using NSK Kogyo's Flattener to flatten the stone before starting sharpening, and using this stone for Metate on 200 grit or under Daimond sharpening stone.
