Why are scissors and kitchen knives polished in different ways?
Grinding refers to putting a knife on a stone and rubbing it repeatedly with water to make the blade thin and sharp. When the blade is too thick to be ground on a stone, an alloy cutter is needed to cut the blade into the next layer in advance and then grind it on the stone.

This profession flourished in the last century, mainly because the material foundation was weak at that time, and ordinary people worked hard for their livelihood and went out to do farm work. They usually put a knife on their body so that they can see what they need at any time and then take it home with a knife. Firewood is used to make a fire and cook, and wild vegetables are used to supplement the shortage of food. Because of the high utilization rate of knives, the blade is easy to wear and the mouth is not sharp, so we can only spend money to buy knives to grind people. Because they have a set of tools for shoveling frosting, scissors are just like new ones, the knives are particularly sharp, and the metal pieces ground by sand are smooth and burr-free. Especially during the Spring Festival, every household kills chickens and sheep.

Hearing the shouts of sharpening scissors and kitchen knives, half the sky will take out its own knives and spend a little money to ask craftsmen to help renovate them. Due to the development of the times, it is difficult to see the traces of these craftsmen now, because every household in the vegetable market is cutting vegetables, and only a few need to cook by themselves, and the knives are not sharp, so they are discarded and bought new ones. In the past, the scene of farmers doing farm work with knives also disappeared, because natural gas from gas stoves replaced litter and briquettes. So now people celebrate the Spring Festival and can't hear the voices of these craftsmen at all.

In the past difficult times, people's living standards were very low. They are short of food and clothes. Eating wild food, wearing rags, kitchen knives and scissors are common tools in their family life. When eating wild vegetables, you need to chop them up every day and use a kitchen knife. Therefore, the car will be unhappy because of the excessive use of Lai Dao. Because of poverty, few people have grindstones, and even if they do, they may not be able to grind them out. I often hear people say that the more unhappy I am,

Living conditions have improved now. Steamed bread, steamed bread, fire and noodles are all made by special people. You don't have to do it yourself, you can buy it with money. As for Lai, you can buy it in supermarkets and restaurants. So you use fewer knives and don't need to use them often.

In the past, because of poverty, people made their own clothes, and scissors were often used when clothes were broken, so scissors were easy to wear. Grinding scissors is a technology and a science. Only those who wait can sharpen scissors, but ordinary people can't.

Times have changed. Broken clothes are gone, and people don't want to wear old clothes. Some people don't even use clothes once or twice, and scissors are rarely used.

Due to the progress of society and the improvement of people's living standards, the industries of grinding scissors and kitchen knives have become a thing of the past and remain in the memory of that generation. However, when we face today's happy life, we should know how difficult it is, which is the result of several generations' efforts. Let each of us cherish life, cherish the present and always have a grateful heart!
