 “Kouseki” – a super finishing whetstone made in 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” is a super finishing whetstone that replaces the 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 has received praise for being effective in sharpening stainless steel and cobalt cemented carbide barber scissors, razors, and the like.
Whetstones manufactured by the magnesium oxide method need only a bit of water to start sharpening with high grinding power. On the other hand, in light of aspects such as deterioration due to continued immersion in water or cracking due to temperature changes and drying, we received requests from our users to overcome these shortcomings without changing the excellent feel in sharpening. So after many long years of research and development, we have succeeded in making this product “New Kouseki (Improved based on customer feedback)” that overcomes these flaws with its no. 10000 (over 1 micrometer) ultrafine particle material and its original vitrified manufacturing method (firing method).
Its sharpening feel and grinding power far surpass the original.
Enjoy “New Kouseki (Improved based on customer feedback)”, which was made without any compromise to its quality.
