The original butterfly knife was named after a small town called Balisung in Batangas, Philippines. The people in this town are famous for the production of butterfly knives. According to the old people there, the skill of making this unique knife is theirs.
Passed down from generation to generation by ancestors, literally, "bali" means split, and "song" means horn. The handle of the early butterfly knife was carved from the horn of an animal, which is a split horn knife.
When fully closed, it symbolizes 3in1forpeace (peace). When half-open, it represents the three geographical areas of the ancestors. When fully open, it symbolizes 3in1forbat (battle).
The length of the butterfly knife is 29cm. This length is not randomly customized. In the Philippines, this length is the famous "veintinueve" (29). In an ancient Philippine legend, a warrior who practiced Philippine martial arts used a knife to fold it.
The knife killed 29 enemies.
Early butterfly knives were made of readily available materials and were very rough compared with Japanese knives. Butterfly knives did not need to pierce thick armor like Japanese knives. In a tropical climate,
The target of the butterfly knife is usually a nearly naked human body. For this purpose, this is enough.
Early farm workers immigrating from the Philippines brought the original butterfly knives to the United States, and they were immediately bought back as war souvenirs by American soldiers. The soldiers called them "click-click" knives because of their peculiar and noisy sound.
For the same reason, Filipino-American youths of this period called them "bali-songs" - "bali" meaning to break, and "song" referring to the "song" produced by the knife.
". Stockton, California and other places, in the eyes of young people in the United States, butterfly knives are as popular as baseballs. Children as young as 5 know how to open it, although they may not know how to use it.
In the 1950s, switchblades became infamous due to the rampage of the Biker Gang, and butterfly knives disappeared for a time. Any knife is a dangerous weapon as long as it falls into the hands of criminals, lawbreakers and Biker Gangs, so the federal government began to pursue them with excuses.
Suppress these gangs. It became illegal to produce, import or carry switchblades across the border. In fact, during that period, even the image of motorcycles was adversely affected. Honda spent millions of dollars on advertising to get people to
Accept "hog".
The resurgence of the butterfly knife is attributed to a Filipino movie star. Just like China has Bruce Lee, Jackie Chan and Jet Li, the Philippines has Danyrusando, who is engaged in Filipino martial arts performances, film and television performances, and Danyrusando began to practice in his Philippines.
Butterfly knives were used in martial arts teachings and movies, hoping to help lift restrictions on butterfly knives. On September 28, 1970, butterfly knives were declared non-switch knives and the ban was lifted.
He designed a butterfly knife sequence in the 1975 movie "The Killer", but it was completely cut out during editing. The film crew felt sorry because "that was actually the best shot ever shot."
". Later, the butterfly knife appeared in Jackie Chan's "The Killer". In this movie, Dan served as the behind-the-scenes director. Since then, the butterfly knife has appeared in movie scenes many times.
In the 1970s, when the ban on butterfly knives was lifted, a company called Lesdeasis used aerospace technology to create the best butterfly knife in history, following Danyulu Santo's pioneering role in the butterfly knife. The knife world was in an uproar.
The butterfly knife he designed was named the best American design of the year by Blade Magazine. Now, he is the president of Pacific Knife Company, and Pacific Knife Company is the only manufacturer authorized to produce bali-song, the only registered name of bali-song.
The owner of the butterfly knife has since left its own reputation in the history of world knives.
In jargon, butterfly knives should be classified as atypical folding knives. Typical folding knives refer to common pocket folding knives. Although the butterfly knife itself is an old concept, in terms of its appearance and function, it is really quite good.
Compact. It completely eliminates the need for a scabbard. It can be conveniently and safely folded into half its length, and the handle has a dual role, serving as a sheath and can be rotated to form a sturdy handle.
The butterfly knife is an improvement on the typical folding knife because it can be opened with one hand. Additionally, the raised handle provides protection from slipping your hand onto the blade. For many years, knives have used carbon steel for their blades.
It is easy to sharpen and sharpen. However, carbon steel is easy to rust and lose its luster. So stainless steel blades appeared, which can maintain a good appearance, but are difficult to polish and keep sharp. Nowadays, most knives are made of high carbon
Made of stainless steel, it combines the characteristics of carbon steel that is easy to crack and stainless steel that is easy to maintain and does not rust.
The craftsmanship of butterfly knives has not changed much, except that the temperature measurement is more accurate than before. All knives are started from purchased steel bars. These steel bars are forged - heated and then hammered
Beat until it is close to the required thickness and shape. Forging is a slow process, during which the steel bar may need to be reheated several times. Butterfly knives are relatively powerful knives, and some butterfly knives can even pierce thin steel plates.
The following procedure is "precision forging", a more refined forming technique. Precision forging is followed by "tempering" which increases the hardness of the metal. Tempering is controlled by temperature and the length of time the steel is in the fire. The blade should last
Heating it to red hot (1500 to 2000 degrees Fahrenheit), and then putting the heated metal into water, oil or other substances to cool it immediately, this process is "quenching". Tempering is a delicate operation.
In ancient times, this was considered a kind of witchcraft, often accompanied by spells and mysterious cooling solutions. In fact, the function of this mysterious solution is just to keep it at a certain temperature, and this method was obtained completely by accident.
.It takes a certain amount of time to recite the incantation, which unintentionally standardizes the heating time.
Tempering makes the tool very hard, but also very brittle. To correct this problem, the tool needs to be reheated at a lower temperature. Once the appropriate temperature is reached, remove the tool and allow it to cool slowly.
The longer it is in the fire, the more elastic it becomes.
The tempered steel can be finally shaped after grinding. In fact, the appearance and performance of a knife are determined by grinding. Grinding is performed with different types of grinding wheels according to the tool design. Small grinding wheels are used
Grinding a small concave edge, while a large flat edge requires a larger diameter grinding wheel or belt. After grinding, the tool is sharpened and polished.
While the blade is being made, the handle is also made in its own process. Typical steps are cutting, drilling, adding metal lining and polishing.
Finally, the blade and handle are connected, and the knife lock is assembled at the same time. Butterfly knives require many testing procedures to ensure that all parts fit tightly and work properly. The blade must be retracted into the handle at the correct angle, not touching the edge, and must be flat when opening and closing.
.Maintain proper clearance, balance and smooth operation. Every butterfly knife of Pacific Knife Company has to go through about 24 hours of work and 85 manual and mechanical processes before leaving the workshop.
The butterfly knife Luo Tian holds in his hand is called Starlight Butterfly Wing. Although it is light and compact, the blade is sharp and as beautiful as a butterfly spreading its wings. However, this beauty is fatal. All the murderous intent is in the butterfly wing.
It is completely hidden underneath. Once the prey relaxes even a little bit, it will become a dead soul under the knife. The prototype of the Star Butterfly Wing is the famous butterfly knife. As an atypical folding knife that can be opened with one hand, the Star Butterfly Wing
Wing's scabbard and handle are integrated. By simply folding, the scabbard can be easily turned into a handle. This knife is relatively high-priced among knives. Due to its craftsmanship, it is very valuable for collection.
The most attractive thing about the butterfly knife is that although it looks simple and plain, it is actually very lethal and often appears in international movies. Its origin, extinction, re-emergence and development are very legendary. As a man,
He said that people are born with imaginations about knives and firearms, and Luo Tian was no exception, so when he was playing with this butterfly knife, he completely forgot about the time. When he glanced at the clock on the wall, he was also shocked.
Big jump, I quickly stopped playing with this butterfly knife and wrote down the identification results.
Of the next five items, four are fakes, including three jades and one bronze. This method of counterfeiting is quite popular, but if it is really applied in practice, it will take some time to accumulate experience and suffer a loss.
People will become smarter as they go through more times. The remaining piece is an imitation of the blue and white porcelain from the Kangxi period of the Qing Dynasty in the early Republic of China. It is an old imitation and the craftsmanship is exquisite. It has a certain collection value and is passable.
The next thing Luo Tian looked at was a pattern of silver. This pattern of silver is also called "foot pattern". The legal standard of silver in the Qing Dynasty was fineness. The Qing court stipulated that payment of money and grain should be based on patterned silver.
The reason why grain silver is used as the currency unit is that the silver actually circulating in ancient China was of different fineness and had many names, such as "Yuansi", "Qingsi", "White Silk", "Water Silk", "Xiqiu" and "Shiqiu"
", "Willow", "Camellia", "fennel", "single tilt", "double tilt" and other names and colors. These different types of metallic silver need to be converted into a unified unit of measurement across the country in order to facilitate tax statistics.
Wen Yin is not an actual silver tael, but an accounting currency unit used to convert metallic silver of various qualities, that is, virtual silver tael, including Guanping, Kuping, Shiping, and Caoping types. According to the official standards of the Qing Dynasty,
The fineness of silver with full grain patterns is 93.5374%, which is called "full grain". The Qing Dynasty regulations stipulated that one tael of grain silver was equal to 1,000 coins. However, after the Qianlong Dynasty, due to the increase in privately minted bad money and the outflow of silver, money often became cheap and silver was expensive.
The phenomenon.
The Qing system stipulated that one tael of silver was equivalent to 1,000 coins. However, after the Qianlong Dynasty, due to the increase in privately minted bad money and the outflow of silver, money often became cheap and silver was expensive. After the Opium War, silver taels and silver dollars were circulated in China at the same time, but the official
Kuping liang and Guanping liang silver are still used as units of measurement when collecting taxes, formulating budgets, and making external reparations. In 1933, the Kuomintang government announced the abolition of the two currencies and the reform of the Yuan, and the silver was withdrawn from circulation.
Grain silver is usually mixed with 92.5% silver and 7.5% copper. Due to the addition of copper, the luster of the finished product after polishing is more dazzling and beautiful than pure silver, and because of the addition of copper, it will fade over time.
Red, so the real grained silver will definitely be reddish in appearance. This is one of the important criteria for judging grained silver. Secondly, judging from the fineness of the grained silver, this piece of grained silver is genuine.
In fact, nowadays, there are also many "grained silver jewelry". It also has a more popular name - 925 silver jewelry, which is named according to the silver content of the grained silver. Nowadays, young people only know about 925 silver, but they don't know this.
The source of 925 is that it only contains 92.5% silver and is a mixed silver.
After Luo Tian wrote down the identification results of the grained silver, he saw an envelope with two big words written on it - please open it carefully. Luo Tian saw that the envelope was flat and expected that there might be something like stamps inside.
I opened it gently and took a look. It turned out that there was a bookplate inside!
