Japanese Natural Whetstone Iyo Meito *Kokuzo* 1601g - Grit 3000 from Ehime  *Free Shipping*


The history of Iyo whetstones dates back to as early as 760 AD, when they were recorded as being used to carve a statue of the Avalokitesvara Bodhisattva. This marks the first mention of a whetstone in official documents, making it the oldest in Japan. However, the extraction of Iyo whetstone, renowned as Japan's oldest natural whetstones, came to an end around the late Showa era. The decline in demand for sharpening stones, coupled with fatal accidents from successive collapses, led to the cessation of mining activities. Entering the Heisei era, to preserve Japan's beautiful cultural heritage, the production of Iyo whetstones was resumed about 50 years after the closure of the original quarry. However, instead of mining from the original mountain, extraction commenced from a new location several kilometers away, leading to a rebranding as iyo-meito from iyo-toishi. This is the Iyo-Meito, which encapsulates 1,300 years of history and the workings of the eternal earth. The whetstones from Iyo in Ehime Prefecture, made from lava, are not only excellent for sharpening but are also admired for their natural beauty, with varying colors and patterns. A sharpening test showed a continuous black slurry like a finishing stone. The density is firm, it resembles the feeling of sharpening with a dense Suita. The line on the sharpening face, it's not Suji ( Toxic Line ), it won't hit when sharpening. Please note that these are not for beginner sharpeners since they're harder to use.These are natural stones meaning that every single one of them are different so my measured size are not accurate. This is a life time investment for people who lives sharpening their knives and tools, do not hesitate to ask me your questions.
