Grinding Japanese stone Suehiro GMN 150 Gokumyo 15,000 grit on a blank 163x20x3mm.
The top line of Gokumyo sharpening stones from the well-known manufacturer of sharpening stones from Japan Suehiro Co., Ltd is the latest development of this company, the brightest, breaking the stereotypes about Japanese water stones as soft sharpening bars that quickly lose their geometry. The Gokumyo series was able to combine seemingly completely opposite qualities in one stone - high bond hardness and a record-breaking abrasive ability at that time, and realized a line of stones with extreme parameters that combined exceptional edge resistance with ultra-high work productivity.
The Gokumyo stone range is the result of many years of painstaking research and experimentation, which made it possible to realize a phenomenally narrow range of abrasive grain sieving and, as a result, a high density and uniformity of abrasive particles on the working surface. The technology has also been improved to realize the ideal microstructure of the abrasive stone bond material inherent in SUEHIRO products. The implementation of this technology makes it possible to obtain an extremely thin and at the same time extremely homogeneous capillary structure of the inter-abrasive space. In addition, the resulting capillary structure is impregnated with a special inter-abrasive impregnation, which makes the stone practically non-absorbent for moisture. This further improves the consumer qualities of the stone, resistance to abrasion, and also eliminates the loss of the geometry of the stone in contact with water, allows you to start working with the stone without pre-soaking, simply by wetting the surface of the stone.
In the Gokumyo series, all stone parameters have been fully optimized to obtain the best results in ultra-fine finishing. The abrasive ability of the stone is reduced to a minimum (although the stone will remove the metal, as evidenced by the active blackening of the working off of the bar), the hardness of the bond has been brought almost to the level of alumino-ceramics. The composition of the bars of the Gokumyo series introduced many components that improve the cleanliness of the treated metal surface, including natural alumina and polishing elements. The response of the Gokumyo honing stones during operation is more like contact with hard plastic than with stone. However, the resulting result makes this series of stones the absolute leader in the field of ultra-fine finishing of cutting tools, especially when working with straight razors.
