Particularities
These stones have a relatively large moisture absorption. The stone must first be submerged for at least 5 minutes in hard-warm water.
Allow it to air dry after use and do not expose it to temperatures below 0 or above 40 degrees Celsius.
Relatively hard stones so few problems with "bite" and extra long life.
Steel residue should not be rinsed during grinding, this has an extra grinding effect.
These stones work best in combination with a Nagura stone
During grinding, the stone must be sprinkled regularly with water.
Grain size (Grit)
The grain size of Japanese grinding stones is expressed in a number. The higher the number, the finer the abrasive grain and the sharper the result. In principle there are 3 types of stones:
- Sharpening stones (Japanese grain size 80-400)
- Whetstones (400-3000)
- Polishing stones (3000-30,000)
Which stone you start depends on the time you have and the state of the knife. If the knife is really blunt or has damage then you start with a grindstone. Then a whetstone can be used to refine the cut. With a less bone or undamaged blade, you can immediately start with a whetstone (for example a 1000 or 1200 stone). It is essential to finish with a polishing stone (normally between 4000 and 8000 grit), this is intended to get the blade razor sharp. The combination between a whetstone (1000 or 1200) with a 4000-8000 polishing stone is in our opinion an ideal starter package. Polishing stones above 8000 grit do not necessarily produce a sharper result, this is also due to the steel grade.
