Kagemitsu Saikō no combination stone #1000/ #4000 -XL-
Kagemitsu Saikō no combination water stone,
Extra large and high quality water stone, can be used on both sides with a Japanese grain size of 1000 and 4000.
Characteristics:
- Dimensions of the stone: 200 X 75 X 30 mm
- Grit: # 1000 / # 4000 grit
- Synthetic resin bound
- Abrasive: Aluminum oxide (Al2O3) (white corundum)
- Includes two silicone anti-slip mats
- China made
Particularities
- These stones have a relatively high moisture absorption. The stone must first be immersed in hard-warm water for at least 15 minutes.
- Allow to air dry after use and do not expose to temperatures below 0 or above 40 degrees Celsius.
- Steel residue and slurry do not have to be rinsed off during grinding, this has an extra grinding effect.
- These stones work best in combination with a Nagura stone
- During sharpening, the stone should be regularly sprinkled with water.
Grain size (Grit)
The grain size of Japanese sharpening stones is expressed in a number. The higher the number, the finer the abrasive grain and the sharper the result. Basically 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 with depends on the time you have and the condition of the knife. If the knife is really blunt or damaged, you start with a sharpening stone. Then a whetstone can be used to refine the cut. With a less blunt or undamaged knife, 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 to get the blade razor sharp. The combination of a whetstone (1000 or 1200) with a 4000-8000 polishing stone is an ideal starter package in our opinion. Polishing stones above 8000 grit do not necessarily produce a sharper result, this is also due to the type of steel.
