This is a high-quality whetstone that does not require you to worry about deterioration or cracking. One of Suehiro's trademark brands, ``Mitsuishi'' was manufactured in the 1970s as a super-finishing whetstone to replace the high-quality natural whetstones that were in danger of running out.It was manufactured in the 1970s using the naturally cured cement method (MG method), which uses ultrafine abrasive particles and magnesium oxide (MGo) as a binder, and was well-received as a whetstone suitable for polishing barber scissors, leather, Japanese razors, etc. made of stainless steel and cobalt cemented carbide. Grinding wheels manufactured by the MG method can be started by simply sprinkling them with water, and are characterized by extremely high grinding power. However, on the other hand, they require care when handling, such as deterioration due to being left immersed in water, and cracking due to temperature changes and drying. We have received requests from users to overcome these shortcomings without changing the excellent sharpening quality. As a result of many years of development, we have overcome defects such as deterioration and cracking due to the ultrafine particle material of #10000 (1μ or more) and the unique vitrified manufacturing method (sintering method) of this product. We have commercialized the super finishing whetstone as ``Custom-made Koishi''. Its sharpness and grinding power surpass the original. Please enjoy the ``Betsuyoshi Koishi'' created without any compromise.
