Shobudani 8-layer, Daigoku quality finishing natural whetstone

Size 20.7 x 7.8 x 3.2 cm
Weight 1,250 g

This stone has a glued cleavage, but it still has a long way to go. If the performance is below average, it would be discarded, but
since it has eight layers, it can be sold. The grinding layer was finished digging about 200 years ago
, but of course it actually exists here.

An eight-ply whetstone was very popular for sharpening artistic swords during the Edo period. The reason for this seems to be that due to the low amount of polishing, there are fewer imperfections and the polishing can be done with fine adjustments. In the Taihei era, swords were not only killing tools, but had already established themselves as works of art.

Even now, when I visit sword sharpeners that have gone out of business, I sometimes come across a variety of eight-layer whetstones. Among them, Nakayama 8 layers are sold at very high prices.

Due to the above features, it is perfect for adjusting the surface of knives, finishing chiseled and planed planes.
Although you don't want to, I think it's safe to say that the probability of encountering eight-layered stones in the future is almost zero.
Quality guaranteed.
