Flattening Stone 600 (for #800~2,000 stone)

> Learn How to Use Diamond Stone Flattener 

All NSK Kogyo's Diamond stones are made with a special formula to create the best cutting edge on the blade, which is the most amazing thing ever. They are made from NSK's many years of their experience and knowledge of producing grinding stones.

• For flattening in the middle of sharpening, maintenance with the Stone resurfacers #120, Large (for below 1500 grit diamond stone) is effective.
  
• For heavy sharpening of diamond stones of under 200 grit, the Stone resurfacers #120, Small (for below 200 grit diamond stone, metate) can be used for metate to revive the cutting speed.
