Usage Instructions:
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.
* To maintain the stone’s ability to sharpen, please clean the whetstone with water and restore the surface with the diamond dressing stone included in the set after each use.
