Suehiro "Gokumyo" GMN150 Finishing Whetstone #15000

by Suehiro


The Suehiro "Gokumyo" series super finishing whetstones are some of the smoothest whetstones you can find on the market. These high density ultra-fine fire-baked ceramic whetstones give the blades a very smooth, sharp edge, pushing the limit of what synthetic stones can give. Comes with a durable plastic whetstone rack and a whetstone surface restorer.

How to use:

This well-made whetstone has a dense concentration of ultra-fine air pockets and can be used immediately by lightly wetting it. Before using the whetstone, either briefly submerge it in water, or wet the surface with your hand, then begin sharpening. Under normal circumstances (summer or winter temperature variations, immersion in water), there is no risk of a loss of quality. It can be used in the same manner as conventional (kiln-fired) whetstones.

How to clean:

To maintain the stone’s ability to sharpen, please clean the whetstone with water and restore the surface with the restoration tool included in the set after each use.
