Natural water stones

Japanese natural sharpening stones, in Japanese ten nen toishi 天然 砥石 are widely known in the world as the world's best natural abrasives, for sharpening any cutting tools including blade (hazard) razors. These stones were found near the city of Kyoto, and have been used as abrasive materials for centuries. There are many mines near the city of Kyoto where toyishi is mined, which in turn vary greatly in price and quality. All mined stones can be divided into two large groups, these are "Eastern stones" in Japanese hagashi mono 東 物, and "Western stones" in Japanese niches mono 西 物. Oriental stones, which are more expensive and more popular, include nakayama, ozuku, narutaki, shoubudani, okudo and others.
Due to the large number of unfamiliar names and the inability to understand how the stones differ from each other, the question always arises as to which stone to buy. The stone for sharpening razors must have two important properties - the stone must be hard and the stone must be finishing. Knife stones are easier - almost all stones are suitable. Finishing sharpening is done on natural stones, and a smooth, sharp cutting edge is obtained. The grain size of Japanese lapping stones is a rather relative concept. Japanese natural stones have such properties, because the quality is influenced not by the size of the abrasive particles, but by the shape. This is confirmed by a study by the University of Tokyo. SiO2 abrasive particles are in the form of rounded flakes. They do not abrade, but remove steel like sod, especially on suspension. The hardness of the stone is an individual trait, although very often Kiita stones are usually softer than Asagi stones, this knowledge can help a little when choosing a stone. But the only reliable way to determine whether toysey is suitable for sharpening bladed razors or just knives is to test the stone and there is no other way. Each stone is individual, even from one shaft and one layer.
Japanese natural sharpening stones are often used only as finishing stones, that is, only for fine sharpening of the cutting edge, at the end of the progression, starting from coarse to small stones (that is, sequential sharpening on stones, 1000-3000 - optional (optional) 6000- 10,000 Japanese grit, and then the finishing natural Japanese stone.But, besides this, the Japanese often do all the sharpening on only one stone, honzan (本 山), while using different nagura to create different suspensions. It is impossible in a short article to describe all the delights of the work on toyishi, but the nature is definitely worth buying.
