Japanese Water Stones

The Japanese water stones are considered to be one of the top ranked in the globe and perhaps the reason for that is the following- the Japanese have been using only natural sharpening stones and they lubricate it with water, not oil. Because if lubricated with oil, the result will be times less effective. Japan is a great manufacturer of water stones as even its land is made for this purposes – the land is made up of stones that include silicate particles and are surrounded by clay. The Japanese system is to combine natural water stones with usual ones. As they are synthetic, they are of course softer but in no case it is a disadvantage. On the contrary, it is a huge plus as the sharpening process goes better and smoother. Also being soft means being not loaded with the knife or any item one decides to sharpen. Apart from all these pros, there is one more – when the water stone wears down, new particles expose and the stone can keep performing the same excellent job. Softness, water and material it is made of- are 3 main key factors for extraordinary sharpening and polishing.
