This is a special large size not generally sold.
It falls into the medium-grit to coarse-grit category.
We believe it is suitable for rust removal and for agricultural tools such as sickles.
Any surface can be used for sharpening.
As this is a natural stone, there may be hard and soft spots, air bubbles, speckles, or minor chips. Air bubbles are often preferred as they hold the slurry. The stone may rarely crack. We cannot offer compensation for this. Please purchase only if you understand the nature of natural stones.
Stones with distinct and beautiful wood grain patterns are more likely to crack from the darker areas.

[Reference Information]
Amakusa Whetstones are mined from the island of Kamiamakusa City, Oyano Town, Kumamoto Prefecture, a place associated with Amakusa Shiro's war funds.
They have long been favored for sharpening knives, carpentry tools, and agricultural tools.
Recently, due to the prevalence of artificial whetstones and the aging of producers, they have become less common in the market.
This time, we are delivering them directly from Amakusa to those who can use them.

◎Chushira (Special Binsui): Between red and white, Chujiro
