Okatsune Sharpening Waterstone

 This Sharpening Waterstone by Okatsune uses only water as a sharpening agent. Slight round radius on one side on stone. Great for pruners. Medium grit waterstone.  Made in Japan.

   First soak the stone in water for about 3 to 5 minutes, then move the stone back & forth in about the same distance while pressing the stone surface along the blade angle. Splash water especially around the contact area between the blade & stone to create muddy droplets, for that does the sharpening, don't wash away or wipe the muddy droplet when sharpening.
