The whetstone we often use can be divided into two kinds: natural and artificial whetstone.
In the market, there are three common whetstones: terrazzo, sharpening stone and diamond.
Terrazzo and sharpening stone are natural whetstones.
Diamond and ceramic whetstones are man-made whetstones.
As we know, before sharpening the knife, the whetstone must be lubricated with water or oil.
Terrazzo and sharpening stone are among those that need lubrication.
Some artificial whetstones can be lubricated or used without lubrication, such as diamond and ceramic whetstones.
But there is one thing in common between the artificial grinding stone and the natural whetstones.
That is, they all have different mesh numbers, which is what we call coarse grinding and fine grinding.
However, it should be noted that different steel and hardness require different thickness and fineness of grindstone to polish, and sometimes even different grindstone materials to polish.
