Gokumyo Flattening Whetstone/#220 Coarse Whetstone GC200-GMSV

This durable, fine whetstone is produced using the Gokumyo method and can be used for surface restoration and edge sharpening.

The slitted side is suitable for surface restoration (especially for Gokumyo products and our other non-absorbent whetstones).
This surface restoration whetstone is just as solid and long-lasting as premium “Gokumyo” whetstone products.

The flat side can be used as alternative to the #220 coarse whetstone.
Compared to other existing products, this whetstone has smoother finish but can be used for quick edge sharpening.


This is a unique use of the “gokumyo method” that cannot be experienced with ordinary whetstones.

Wet lightly and it’s ready to use as this product is high density with fine perforation. Dip the whetstone into water or apply to the surface by hand, then start whetting. Product quality does not change under normal conditions (including temperature difference between summer and winter) or by soaking in water.

To use as surface restoration whetstone


Please use the slitted side for surface restoration.
To achieve a level surface, please wet both the whetstone and the surface restoration whetstone and rub them together

To use as a coarse whetstone

Please use the flat side as a coarse whetstone.
Before use, pour some water onto the whetstone. This product is for correcting chipped blades. If necessary, please use a medium and finishing whetstone afterwards.
