Water Roll Sharpener

Natural whetstones have a unique polishing property. A Japanese sword sharpened with a natural finishing stone will have a luster and a beautiful blade pattern. On the other hand, natural whetstones have impurities that can damage the blade during sharpening, they naturally crack, and their hardness differs from one to another, making them very expensive. As a result of their research towards developing a whetstone that anyone can afford to purchase and handle safely and easily, Suehiro has developed the synthetic grinding stone of today. Compared to natural grinding stones, synthetics may seem to lack value, but in terms of quality, synthetic grinding stones are superior up to the limit of medium-grade grit stones. Suehiro has developed finishing stones that have the same sharpening performance as natural whetstones. To ensure the best performing material and product, the whole process, from design to manufacturing, is done in-house.
