Tanaka TOISHI WA #3000 Michibiki is a traditional Japanese water whetstone from Kyoto. It is a soaking stone that requires approximately 10–15 minutes of soaking before use.
Product dimensions may vary slightly. I measured two stones, and both were as follows:
Grit: #3000
Length: 218 mm
Width: 85 mm
Thickness: 31 mm
NOTE!
This whetstone is a so-called soaking stone. It works best after 20-30 minutes of soaking. After sharpening, immediately wipe the stone clean with a towel. This will give the stone a clean look and start the drying process. Place the stone to dry in a position where it does not touch a solid surface. For example, place the stone on top of a pencil. Allow the stone to dry slowly without additional heating. Do not place the stone in direct sunlight. Do not allow the stone to freeze when wet. It takes more than 24 hours to dry. Store the stone protected from dents, e.g., in its box.
