"Kouseki" — a super finishing whetstone made by the magnesium oxide manufacturing method, used for polishing blades for hairdressing in place of natural whetstones. We reproduced the hard, tightened, and smooth sharpening and grinding power by our original firing method. It is a high-quality whetstone with no worry of deterioration or cracking.
As one of Suehiro's trademark brands, "Kouseki" replaces high-quality natural whetstones, which have long had issues of quick depletion. It is made by the magnesium oxide method, a natural cementing method from the '70s that combines ultrafine abrasive particles and magnesium oxide (MgO), and is effective in sharpening stainless steel and cobalt cemented carbide barber scissors, razors, and Japanese razors. After many years of R&D, we made this product "New Kouseki (Improved based on customer feedback) SRK-10000," which overcomes the flaws of immersion-related deterioration and cracking with its no. 10000 (over 1 micrometer) ultrafine particle material and original vitrified (firing) method. Its feel and grinding power far surpass the original.
