Because I don't know the specific product, the following is an example of "compass", imitating the classical style of "Tiangong Kaiwu" to answer:
Today there is a thing, which is exquisitely made, used in all things of travel and navigation, and has great functions. It is called the compass.
The compass of the husband, originated in the ancient Sinan. Its shape, at first like a spoon, was made of a magnet, placed on a smooth copper plate. The guide of the magnetic spoon handle, then it is a tool for distinguishing direction. After evolution, the shape gradually changed. There are needles that are magnetized, pierced through the wick grass, floating in the water vessel, and the needle is always north and south. There are also needles that are suspended with silk thread to make them turn lightly. When still, the needle is clear to the south and north.
The essence of this device lies in the nature of a magnet. A magnet attracts iron and has a guide to the north. The craftsman takes the magnet, finely grinds it, and makes it into a needle shape. After ingenious craftsmanship, the needle is magnetized. Or rub the steel needle with a natural magnet, or calcine the steel needle near the magnet, and wait for it to cool, the needle contains magnetism.
Its use is also in the vast sea, traveling thousands of miles, with rough waves, clouds and fog covering the sun, and the direction is difficult to distinguish. Holding a compass, you can set the course and keep the boat moving forward safely. In the mountains and wilderness, a traveler is lost, and according to the compass, he can also find the right way.
The ancient navigators relied on this device to travel across oceans and open up foreign territories; military expeditions, between mountains and rivers, determined the road of march with this. The benefit of the compass benefits the world, and it is indispensable for the world to travel and explore.

The ideal quality of this product is related to materials, craftsmanship, uses and many other aspects.
When it comes to materials, it is important to be fine. Like good gold and jade, the texture is firm and pure. If you make a sword, choose iron to seek its essence, and there are very few impurities, so that you can forge a sword with a sharp edge and a combination of rigidity and softness. Using good wood as a material also needs fine texture, solidity and durability. If you make utensils, it can be guaranteed for a long time.
Looking at its craftsmanship, it needs to be exquisite and delicate. In the past, all the craftsmen had stunts, and they poured their efforts into the carving of utensils. When casting bells, the heat was precisely pinched, and the molten copper was not bad, so that the bell could be loud and clear, and spread far away. The art of embroidery, exquisite needles, silk thread shuttle, embroidered flowers, birds, fish and insects are lifelike, as if they are agile and want to fly.
As for the use, it must be practical and convenient. The purpose of the carriage, horse and boat is to travel far, when it is stable and light, and it is convenient to carry people and goods. The food utensils need to be of suitable size, reasonable shape, and easy to hold and use, so as to support the needs of food and drink. The study utensils, such as the edge of the pen, are moderate, the color of the ink is rich, the paper is flexible and absorbs ink, and the inkstone is delicate and inky.
In short, products of ideal quality, with excellent materials, exquisite craftsmanship, and practical uses, are rare and good in the world. They can be passed down for a long time, praised by the audience, and are beneficial to life, skills, and other aspects. They are treasures of the world.

The method of making this product is as follows:
First take the best quality material, its quality needs to be strong and tough, and the color is warm and moist. Use an axe to cut the chop to remove the unevenness and unevenness, so that the material is straight and the size fits. The craftsman upholds the heart of specialization, examines every texture, and applies force according to its direction, without violating the wood.
Then, it is prepared with all kinds of exquisite tools. For sawing, the blade is sharp and the teeth are dense, and the broken material is precise and unpleasant; the planing is as smooth as a mirror, which can make the wood surface shine. In the system of mortise and tenon, it is particularly critical. To cut the mortise, the depth is shallow and wide, and it is all in line with the rules. The mortise fits perfectly with it, as if it were made in heaven.
Furthermore, paint with various colors. Choose a natural paint and grind it to make it elegant, or scarlet solemn, or green and quiet. When applying the paint, it should be thin and even, and each layer should be painted layer by layer, and then the next layer should be made. After the paint is dry, wipe it carefully with a soft cloth to make the utensils glow with a soft luster, which not only enhances the appearance, but also protects the wood for a long time.
And when making, it must be at the right time and place. When the weather is dry, the material will crack easily, and when the weather is wet, the paint will be difficult to dry. Therefore, when the wind is gentle and the sun is beautiful and the dry and wet are appropriate, this excellent work can be achieved. In the workshop, the craftsmen have no distractions, and they have become the trend. With the techniques of inheritance, they have injected their efforts into every detail, and finally achieved the synthesis of this excellent product.

When using this utensil, many matters need to be paid attention to.
First, check its quality. When using it for the first time, check the texture of the utensil carefully to see if it has any flaws or cracks. If the texture is not good, it may be damaged suddenly in the process of subsequent use, and the user will be at a loss, or other objects may be damaged. For example, porcelain utensils, check whether the glaze surface is uniform, whether there are bubbles or lack of glaze; metal utensils, check whether they are well-cast, whether there are trachoma or cracks.
Second, understand their use. All kinds of utensils have their own specific uses, and must not be misused or abused. If cooking utensils are used for cooking, if they are misused for other purposes, it will not only be difficult to achieve the expected effect, but also may cause damage to the utensil itself. For another example, a special measuring tool, when used for accurate measurement, should not be used in other ways at will, so as not to lose its accuracy.
Third, operate with caution. When operating the utensil, be sure to exercise caution. If you use too much force, it may cause damage to the utensil; if you don't use it properly, it will be difficult to achieve the desired effect. If you handle a knife, the posture of holding the knife must be correct, and the force of carrying the knife should be uniform, otherwise it is easy to hurt yourself, and the knife is also easy to wear. When using fragile utensil, you should handle it with care and beware of falling to the ground.
Fourth, proper maintenance. After use, proper maintenance is essential. Different utensil maintenance methods vary. Wooden utensils should be protected from water and moisture to prevent deformation and decay; metal utensils should be protected from rust, washed and dried after use, and protective oil can be applied if necessary. Regular inspection, cleaning and maintenance of utensils can prolong their service life.
Fifth, suitable environment. The use environment of utensils should not be ignored. Special environments such as high temperature, humidity, acid and alkali may have adverse effects on utensils. Such as electronic products, should be avoided in high temperature and high humidity; containers for chemical products should be placed in a suitable environment according to their characteristics to avoid damage to the container due to corrosion and cause danger.
