Iyomeito is a whetstone with Iyome wood grain, which, as its name suggests, looks as if it was carved out of the trunk of a large tree. It was once called "Tiger" and was treated as a third-class product, but since the mountain it is mined from has changed, it has become a highly popular whetstone, not only for its appearance but also for its high quality. Compared to other Iyomeito, it is of medium hardness, so if you are looking for a medium whetstone, this will be your only companion.
