There must be a knife in the engraving, and the engraving knife is an extremely important tool for engraving the seal. For the primary printing friends, the tungsten steel knives can be said to be more suitable for quick start "knife pen". It can be your partner on the road, accompanying you and growing up with you. For the old Indian friends, it is like an old friend. Of course, I believe that the Indian friends also know that the engraving also needs to work hard in terms of lettering, law, rules, and knives.
As the saying goes, "If a worker wants to do something good, he must first sharpen his weapon." As an engraved enthusiast, having a good "printing knife", it is a must, of course, the "slaughter knife" is not used. This is like the ancient literati and the literati have a preference for pen and ink, and today's author is also eager to see this "pen". I hope that the Indian friends of the world will have such a tungsten steel engraving knife, and they will be able to "catch the world" and sit on the "world".

For the primary Indian friends, may not know what is the tungsten steel engraving knife? Next, the author will take you to know. Tungsten steel knives, also known as carbide knives, are a common type of knives. They are generally made of tungsten carbide as the main raw material and processed by a series of processing techniques using powder metallurgy. Its Mohs hardness is about 7. The Mohs hardness of the four famous stones (Qingtian Stone, Balin Stone, Shoushan Stone, Changhua Stone) is generally 2~4. That is to say, the use of tungsten steel engraving knives for engraving does not require much effort, and there is no problem with ordinary stone materials. Common knives also include carbon steel knives and white steel knives. Carbon steel knives have a Mohs hardness of 4 or less and a crisp texture. The white steel knife has a Mohs hardness of about 6, the hardness is high, and the toughness is slightly better, but its knife size is not very good. For the price of these "printing knives", among the three, tungsten steel knives > white steel knives > carbon steel knives. In India, you can choose according to your needs and economic ability.

Due to the characteristics of tungsten steel raw materials and the exquisite craftsmanship of the engraving knives, the tungsten steel knives have better wear resistance, longer service life and corrosion resistance, so there is no need to worry about not being durable or rusting. It only needs a little maintenance. Of course, this depends on how often you use it. It depends on your habits, and the Indians who prefer blunt knives are another matter. And the white steel knives, you need to oil it, but also pay attention to keep it away from the water, but also regularly polished, it is more troublesome. However, everything has its advantages and disadvantages. The toughness of tungsten steel is not as good as that of white steel, so it is not easy to fall off the ground.
Why do you need to know the engraving knives of these different materials? Because the raw materials used in the knife and the size, weight and purity of the knife will directly affect the expressive power of the engraving.
For the primary Indian friends, you can also find out what the knives such as "flat knife", "boxing knife", "tweezing knife" and "golden knife" are what? First of all, what do you know about the imprinted objects? Stone, wood, jade, crystal, porcelain, ivory, rhinoceros, gold, silver, copper, etc. The quality and form of the knife are therefore different. "Ping Knife" is named for its flat head and double-sided appearance. It is also called "carved stone knife", which is mainly used for engraving stone seals. The "fist knife" is named after the knife is like a fist, also called "carved wooden knife", mainly used to engrave the wooden seal. "Carved jade knife", its knife is dry and the knife edge is square. The blade is attached with a wooden handle and fixed with iron hoop. It is mainly used to engrave the jade seal. The “tweezing knife” is named after it is used to remove the printing base after double hooking with a flat knife. It is also called “carving angle knife”. The blade body is thin and the blade edge is beveled. It is mainly used for engraving teeth. Horny seal. "Golden knife", its knife edge is thin, single-sided out, the middle part of the blade is round, also known as "engraved metal knife", mainly used for engraving metal seals such as gold, silver and copper.
For the blunt effect of the engraved pen, it can be properly ground. You can use a harder diamond disc to grind the tungsten steel knives, which is not only fast, but also effective.

Maybe the Indians also know the word "blunt knife hard", but they can't tell the concept of it. In fact, the "blunt knife hard into" is a knife method, because the knife used is blunt, you need to increase the strength of the wrist, and choose the hard method. The density of tungsten steel knives is large and sharp, and it is heavy. It has a texture in the hand, so the control of the knives and seal lines will be better controlled, and then it can be carefully crafted.
It should be noted that the tungsten steel knives are only suitable for engraving stone seals and plexiglass seals. They are not suitable for hard materials such as jade seals, porcelain seals and crystal seals. When engraving the seal, please do not hit the tail of the knife with a hoe or the like to prevent the blade from cracking or even breaking. Tungsten steel knives should also prevent falling on hard floors such as cement and tile floors to prevent damage to the cutting edge. If the blade is inadvertently damaged and a small piece of chipping occurs, it is recommended to replace it with a new one or use a diamond disc for grinding. When grinding, the direction of the general grinding is the same as that of the engraving knife, and the grinding is performed forward or backward to ensure the smoothness of the blade.
