---------------------------------------------------------------------- Less than 20km northeast of Tobe Town, Ehime Prefecture, which is known for Iyoto. A majestic and beautiful columnar joint cutlet that can be found deeper in the mountains than Sakurasanri on National Route 11. This is a whetstone cut from Matera ore, which was discovered on an unprecedented scale. We have received a lot of praise as a result of the trial distribution distributed to various professionals. Also, now that we have a plan for production and quality control, we would like to widely recruit test pilots who can use the product at a limited price. It is difficult to get slime on the surface and it is easy to maintain clean conditions. It is an igneous stone whetstone that exhibits unparalleled alkalinity and is resistant to rusting during sharpening. It has strong antibacterial properties, surpassing silver in terms of powder, salmonella, and E. coli. Approximately 75x80x25mm 360g Rich in feldspar and mica, it has a very good sharp taste as long as it is soaked in water for 5 minutes before use. The grain size is higher than it appears visually, so it speeds up the finishing process later on. You can restore the grinding ability by polishing it with a diamond whetstone or by rubbing it with a similar stone made in Italy, so please prepare small pieces and a whetstone. They are classified by variety and size, but there are individual differences in pattern and color. For more information and trial sharpening information, please see below https://bit.ly/3E6BvtE
