The material of this product is cast by cold iron. Cold iron is born in extremely cold places, and is bred by thousands of years of cold ice. Its texture is incomparably hard and has a natural chill. Its color is jet black, faintly emitting a faint light, which is comparable to ordinary iron.
The products made of cold iron are quite heavy. Under the same volume, they are more than several times heavier than ordinary iron products. When held in hand, they feel cold at first, and then the chill penetrates the bones. If ordinary people hold it for too long, they may not be able to withstand the bone-piercing cold and hurt the meridians.
This product is abnormally sharp. Cold iron has been tempered by skilled craftsmen, and the edge is polished as thin as a cicada's wing. It is not a problem to blow hair and break hair. And because of its special texture, when it intersects with other blades, it can often easily cut off the opponent's weapons, and the sharpness is far better than that of ordinary swords.
Furthermore, this product has excellent toughness. Although cold iron is hard, it is forged by a unique process. It is not blindly hard and easy to fold. Instead, it is rigid and flexible. When it is subjected to a strong external impact, it can bend and deform without breaking. When the external force is removed, it can be restored to its original state. This characteristic makes it more advantageous in actual combat and can adapt to various fierce struggles without damage.
In addition, cold iron also has certain strange characteristics. Under certain circumstances, it can echo the cold air between heaven and earth, as if it becomes a carrier of cold, causing the temperature to drop sharply within a certain range, which has a deterrent and interference effect on the enemy. Products made of these materials are rare treasures in the world.

The chemical properties of this product are particularly important, and it is also related to its use.
From the perspective of its properties or stability, it is not easy to respond to other things in various environments, and its quality is maintained. Such as gold, it is left empty for a long time and does not rust quickly. The cover is stable because of its chemical properties, and it is less responsive to oxygen. If this product has this property, it can be stored for a long time without deterioration. It is convenient for the user to change and cannot be used.
It may also be active, easy to combine with other things and generate new substances. Just like sodium in contact with water, it responds quickly, starts fire and deflates. If this product is active, it can be used in the chemical industry to produce other substances. With its ease of response, it can produce a variety of useful materials.
It is also soluble, either soluble or insoluble in water or other agents. If it is soluble, it can be made into a liquid product, which is easy to disperse and apply. If salt is soluble in water, it can be used as a seasoning or a solution. Insoluble, or in a solid state, it has its own special use, such as pottery material, insoluble in water, and can be used as a container to hold things.
Its acidity and alkalinity are also important. If it is acid, it can be mixed with alkali, neutralized and raw salt and water. If vinegar contains acetic acid, it can be descaled because of its acid and alkali in scale. If it is alkaline, the same is true, and it can be mixed with acid. If this product has acidity and alkalinity, it has its own uses in cleaning, cleaning, chemical processing and other industries.
Furthermore, the redox property should not be ignored. Those who are easily oxidized need to be prevented, such as iron rust easily, which is dissolved by oxygen. If this product has such concerns, it should be protected by law, such as painting, gold plating, etc. Those who are easy to reduce can be used in the metallurgical industry to make the oxygen of gold pure gold.
In short, the chemical properties of this product are all kinds, stable activity, dissolution, acid-base, redox, etc., all depend on the wide and narrow use of it. The method of preparation is crucial in the fields of industry, agriculture and health.

The production process of this product is quite delicate. At the beginning, the materials must be carefully selected, and all materials need to be of high quality. For example, when smelting a good tool, the ore mined should be pure and free of impurities, which can lay the foundation for the subsequent process.
Then, in the shaping stage, the craftsman uses his exquisite skills, either casting or forging, to gradually form the material into the desired shape. Casting requires controlling the heat, so that the molten iron or other materials are melted without coking, poured into the model, and precise, in order to obtain the prototype. The forger, the hammer is powerful, the rhythm is orderly, and the material is dense and rigid under the repeated tempering.
Furthermore, the surface treatment is also crucial. Or polish it to make it as smooth as a mirror and feel warm to the touch; or add lacquer, chisel and other techniques, lacquer it will be bright in color and new for a long time, and the pattern formed by chisel will be fine and subtle, lifelike, increasing its beauty and artistic value.
And in the production process, every step has strict rules. Craftsmen need to strictly observe the process and must not be slack in the slightest. Each link is closely interlocked, such as a chain that is interlocked. If one chain is damaged, it will be completely discarded. Therefore, through such a complicated and rigorous production process, this excellent product can be obtained, which is both practical and ornamental. It is really a combination of craftsmen's heart, blood and wisdom.

Today's products are in the market, and their competitiveness is related to various factors.
The quality of the husband's products is the first to bear the brunt. If the quality is not high, although the rhetoric is used to decorate it, it is difficult to hold on to the market for a long time. In the past, there were good workmanship tools, which were carefully selected materials and carefully carved, and did not dare to slack in the slightest, so that the best products could be handed down. Today's products, if they want to be competitive, must be based on quality, like the strength of gold and stone, which cannot be broken.
Furthermore, their efficacy should be appropriate to the needs of the times. The world changes with time, and the needs of the people also change. Ancient utensils, whether for farming or for war, are made in time. Today's products should also have insight into the needs of people at the time. If they meet the needs of people's convenience, comfort and intelligence, if they are needed against the times, the quality of the product will be useless.
The beauty of the appearance cannot be ignored. Everyone is beautiful, and the shape that is pleasing to the eye can often attract customers to stop. In the past, there were craftsmen who painted splendid pictures on the utensils, engraved with exquisite patterns, so that the utensils are both practical and beautiful. Today's products should be integrated with aesthetics and design, and the beauty of the shape is touching.
Whether the price is appropriate or not is also competitive. If the price is high, the customer is rare, and the price is low and the profit is thin. It is necessary to weigh the quality, work, capital and the supply and demand of the market, and ask for a suitable price. Just like the merchants of ancient times, they observed the prosperity and deficiency of the city, and observed the dignity and inferiority of things. They sold them at the right time, so that they could reap great profits. The pricing of today's products should also be based on the situation and make the price worthwhile, so that they can be accepted by the city.
Furthermore, the reputation of the city is also heavy. Only when everyone praises it can they be trusted by customers. If there is suspicion of deception, bad deeds will destroy their reputation in one fell swoop. The good merchants of ancient times built the world on trust, and the children were not deceived, so they could flourish for a long time. Today's products should be valued for the reputation of the brand and based on integrity, so that they can win the trust of customers and the recognition of the city.
To sum up, if this product is to be competitive in the market, it must be of high quality, suitable for work, beautiful in shape, suitable for price and good reputation. All elements complement each other and are indispensable. In this way, it can stand firmly in the torrent of the city and travel unimpeded.
