How about giving someone a knife?

Analysis:

This is a good gift, especially a "Swiss champion". Very elegant.

Shopping malls sell more than 700 "Swiss champions" and buy more than 300 on bags. It's cheap because it's smuggling.

You can look at the following information and get to know it.

There are only two brands of real Swiss army knives in the world (we usually refer to two kinds of Swiss army knives, one with a shield and the other with a round mark), namely Victorinox and Wenger. Victorinox is currently the largest tool manufacturer in Europe, located in the small town of Ibaco, Schweitz, surrounded by mountains in central Switzerland. 1884, the knife maker Karl elson established a knife-making workshop here, which is the predecessor of today's Victoriano company. 1909, Elsanna's mother passed away. In memory of her, the factory was named after her name Victoria. The local stainless steel (Inox) appeared after 192 1, and the word "stainless steel" was added to the company name, thus forming the well-known Victorinox brand. After more than 100 years of wind and rain, the company has developed from a manual workshop with only more than 20 people to a large tool factory with more than 1000 employees, producing more than 100 knives every day, 90% of which are exported abroad. The company's products have also developed from the initial 1 to more than 800 kinds at present, and the current chairman is Carl elson III, the grandson of the founder.

Vickers saber:1invented in 884.

Vexcor is not only a world-famous saber, but also a "multifunctional tool", which is widely used in tourism, mountaineering, diving, model airplane sports, bicycle repair, automobile repair and daily life.

Victorinox, a Swiss army knife, is a good gift and the pursuit of perfection is a consistent tradition of Victorinox, a Swiss army knife. After years of research and innovation, every part of the knife has reached the best shape and perfect function. Therefore, it was chosen as a White House gift by many American presidents, and the handle was engraved with the president's signature for the guests. NASA also listed it as a portable tool for astronauts. In addition, many multinational companies and banks in the world carve their names or trademarks into advertising materials and conference souvenirs for customers.

Vigo Saber: Pure Swiss Saber was born in 1893.

1900, with the cooperation of Mr theowinger and Mr Henri Sandas, president, Swiss Vigo company was formally established. For a century, Swiss Vigo Company has continuously enriched, enriched and perfected its famous products with a long history of 100 years. Today, Vigo has become a leader in the world tool industry and a very competitive product in the world tool industry. Vigo's pure Swiss army knife is also known as "a high-quality tool product made by watch technology".

How to distinguish the authenticity of Vichy Swiss army knife;

First of all, look at the English of the main knife root

The following lines will be written in English on the front of the root of the main blade of the authentic VICTORINOX Swiss Army Knife:

mauricio victorino

Switzerland

rustproof

Rostefi

Generally speaking, they are in the first four rows, but recently I have occasionally seen the styles in the last three rows. (Most 58, 74, 84, 9 1,11mm sabers are like this. )

mauricio victorino

Swiss made

rustproof

1 1 1mm saber with the number beginning with 0.84 is basically the following three lines of English:

mauricio victorino

Switzerland

rustproof

Rostaffy has no top row.

Most vexcor Swiss army knives also have English on the back of the main blade root (58mm, 74mm, 0.695438+00, 0.85438+00 is not available):

84mm, 9 1mm saber has a small umbrella-shaped thing painted on the back of the main blade root, and there is a "+"sign on the lower left of the umbrella. Below this pattern are two lines of English:

police officer

Switzerland

1 1 1mm saber has two kinds of English on the back of the main knife root. According to the different locking methods of the main knife, the English is also different, namely:

The saber with unlocked back is written on the back of the main blade root:

patent

Blade root unlocked saber (commonly known as thread lock) is written on the back of main blade root:

Degeneration

9305297

There is also a special case here, that is, the knife on the card of Swiss Army Knife doesn't have any English, so it can't be said that this knife is fake.

In the past five years, the authentic Vichy Swiss Army Knife will have the above English words on the root of the main knife. Those who fail to meet the above requirements can basically be judged as imitations or fakes. Don't think it is easy to type these English words. As far as small factories in China are concerned, it is difficult to type these words properly. Forgery doesn't care about such details when pursuing profits. If the Swiss army knife is completely copied with steel, the cost will be quite high, and there will be no market in China, because the cost may exceed the imported authentic Swiss army knife.

Secondly, look at the Peugeot of Swiss army knife.

1, metal inlay, which is the favorite manufacturing method of most saber lovers. It uses optical technology to embed metal chromium into plastic handle and then fasten it by pressure. This Peugeot is particularly beautiful and shines in the sun. Most of the sabers numbered 0.6 series, 0.3 series, 1.3 series, 1.4 series and 1.6 series are of this Peugeot. Some exceptions are 0.6 series and 1.4 series with lights.

2. Hot pressing, which uses copper molding to prevent metal foil, temperature and pressure engraving. The carving is deep and difficult to erase. 1.4 series sabers, such as 1.4733.72, 1.3653.72, 0.69 10 Peugeot, have done this in some batches.

3. lettering is basically what we often call the economic edition. That is to say, a shield-shaped pit is first made on the front of the handle with mechanical equipment, and then special silver paint is sprayed inside, which will wear off after a long time, leaving a shield-shaped pit at last. Most sabers engraved with Peugeot are frosted, such as 3.3703, 2.3803 and so on. 2.6223 is an exception, its handle is very smooth and has a beautiful etching. Careful buyers will find that the economic version of Peugeot and the standard version of Peugeot are not exactly the same. The cross in the standard version is connected with the shield frame, while the cross in the economy version is not connected with the shield frame. The reason is that the metal version of Peugeot is embedded in the handle of a metal plate. If the cross is separated from the shield frame, it is not easy to align when embedding. Therefore, the cross in the standard version is connected to the shield frame.

4, rolling, that is, we often say printing. 1 1 1mm sabers are mostly like this. This kind of saber is more wear-resistant, but it will fall off if it is scratched with sharp tools for too long. The Peugeot of the sword card is also rolled. The "German Saber" model is an exception. Its Peugeot is an eagle with an integrated handle.

There is also a camouflage handle, and a buyer friend said, why not a metal Peugeot? Camouflage handles are different from the above models. They are made in the molding process and injected directly into the handle, so they are not made of metal. I think there is another reason. Vichy manufacturers want Peugeot to match the handle, so they also integrate Peugeot's color into the main color of the handle.

Luxury hilts and Peugeot are not discussed in this post, such as high-grade wooden handles, shell handles and pure silver and gold handles.

Look at the workmanship. Most fake Swiss army knives cost only a few yuan, or even less. Generally speaking, the material is iron, which is easy to rust. The joint is not aligned, and there are many metal corners or burrs. The material of the shell is low-quality plastic at first glance, which can be seen at a glance from the appearance and workmanship accuracy, and it is easy to distinguish.

The story of the Swiss army knife

Founder of Swiss Army Knife: Karl

Charles elson, the fourth son of the shoemaker Balthha elson Ott, is determined to be a tool worker. After working as a worker in tuttlingen in southern Germany for several years, he returned to his hometown at the age of 24 and opened his own factory in Ibach near Schwartz in 1884.

At that time, there was hardly any industry in Schwiertz, so many young farmers were forced to emigrate to North America, Australia or New Zealand. In order to create new employment opportunities, Karl elson initiated and founded the Swiss Tool Industry Mutual Aid Association in 189 1. Its main purpose is to make soldiers' knives, which the Swiss army must buy from solingen. 189 1 10 in June, the association made the first saber for the Swiss army. After that, Karl elson began to make other beautifully designed knives. He used names such as student knife, officer knife and farmer knife, and did not use numbers to distinguish them. Soldiers' knives are big and heavy, so Karl elson specially made a lighter and more beautiful knife for officers. This knife has a small blade and a bottle opener besides all blades, awls, canned screwdrivers and screwdrivers on soldiers' knives. This new model with six blades on two springs is called "officer's knife" by Carl. This design has been officially registered in 1897.

Unique design: the birth of "Swiss champion"

This convenient multifunctional knife quickly became very popular and began to receive more and more orders from abroad. The function of the knife is constantly improving, and soon tools such as wood saws and scissors are added to the knife. Soon, the big screwdriver was added with a bottle cap screwdriver, and the can screwdriver was added with a small screwdriver. Then nail file, toothpick, tweezers, metal saw with metal file, scale remover with hook and scale, cross screwdriver, key ring and magnifying glass were added to the knife. Today's Swiss army knife can have 100 multiple combination functions. Among all kinds of sabers, the "flagship" is the "Swiss champion" with 3 1 function. The total weight of all tools and tool box of this knife does not exceed 95g (6.5 ounces), so it is easy to carry. The Museum of Modern Art in new york and the German Museum of Applied Art in Munich both collect VICTORINOX's "champion" as "excellent industrial design". "Swiss Champion" consists of 64 independent parts, which need to go through more than 450 processes in the production process.

Mother's Monument: Victoria (Victoria)

1909, after Karl elson's mother died, he took his mother's Christian name victory as his trademark. Stainless steel is found in 192 1. Therefore, after the stainless steel knife was made in Ibach area, the word INOX was combined with VICTORY to form the trademark of VICTORINOX, which has been used ever since. Today, VICTORINOX has more than 950 employees. It is the largest industrial enterprise in Schwiertz and the largest tool manufacturer in Europe. 1945- 1949, VICTORINOX pocket knives were sold in large quantities to the specialty stores of the American armed forces, which also made the Swiss army knife famous all over the world. For American officers and soldiers, the name "Offiziermesser" is too difficult and taboo, so they call it "Swiss Army Knife" for short. Now this name has become a household name in English-speaking countries and regions. Known as "Couteau Suise" in France and "Schweizer Messer" in Germany and Austria, both refer to Swiss knives. US President lyndon johnson once presented 4,000 knives with his initials engraved on them to his guests at the White House. Later, Presidents Ronald Reagan and George Bush followed this tradition.

World-recognized "quality trump card".

Swiss diplomats and senior military officials often present Swiss army knives to the host countries they visit. Swiss army knives are particularly attractive to pilots. 1960, after FRANCIS GRAY POWERS, the pilot of the U.S. U2 reconnaissance plane, was shot down over Russia, the Russians made all his belongings public, including the famous red Swiss army knife. The Nigerian Air Force has ordered a large number of Swiss army knives with curved blades, which can be used to cut the ropes that bind parachutes and escape at low tide. Because the Germans also bought Ibach's saber from 1976, the Swiss "+"bears the German Eagle on the olive-green scabbard. NASA also listed the Swiss Army Knife as standard equipment for the space shuttle Columbia. "Swiss Army Knife" is often copied in Germany, France, Spain, the United States, Japan, China and other foreign countries, but the quality is not as good as the original. Unfortunately, however, many foreign copies were printed with Swiss crosses, which had to be stopped by mediation ordered by the Swiss ambassador and the court. Criminals drew a cross on the saber to confuse the authenticity, but only two Swiss manufacturers, VICTORINOX and WENGER, were officially authorized to use the cross on the saber.

Some of these names are used to explain the "figure" of the Swiss army knife. Swiss army knives generally have three specifications according to their length (handle). Take Vickers Saber as an example, there are three types: small, medium and large, which are 5.8 cm, 9. 1 cm and11cm respectively. Knife is suitable for women or teenagers in combination function, and it is carried with a key chain, which is mostly used in home life, such as "Boy Scout" and "Mini Champion". Because of its moderate length, medium-sized knives can be used as a common tool for outdoor travel and a good helper for home life and work, such as "chairman". However, broadsword usually holds the handle and feels comfortable. It often appears in some "big scenes" such as field trips and mountaineering expeditions, such as "hunters" and "work champions".

In addition to the design differences in size, the Swiss Army Knife mainly combines hundreds of models with different purposes and uses, such as campers, climbers and enthusiasts for outdoor travel and adventure mountaineering, fishing kings and fishermen, car enthusiasts and craftsmen, and managers specially designed for managers.

Take the "Swiss champion" as an example. The big (small) knife is the most commonly used tool, which is very sharp and suitable for cutting ordinary objects.

Multi-purpose hook-afraid of the heavy bag pulling the delicate fingers beyond recognition? Then hook the handle of the bag with this hook, and just hold the comfortable handle tightly. It is not a problem to lift heavy objects.

Magnifying glass-an essential item for studying maps. Ballpoint pens are used to take notes.

Bottle opener-For the health of teeth, please use more bottle openers and less brute force.

Pin-a small thing that is usually used for other things. It can be turned into a fish hook at a critical moment and become a weapon for survival in the wild.

Turn the screwdriver-there's something wrong with the home appliance, so it's too much trouble to find someone to fix it. Then do DIY yourself. Large and small screwdrivers, cross screwdrivers, wire stripping slots and pliers can handle most situations, unless you want to disassemble the car.

Nail file —— Long-term outdoor activities can easily damage long nails, and toenails may also stab feet and cause wound infection.

Scaler- I finally caught a fish while camping. I scraped the scale clean with a scale scraper, and it was not embarrassing at all.

Wood saw-what if there is no tableware in the wild? Just use a wooden saw to saw some bamboo, so that you can use the bamboo tube as a rice bowl, and you can also saw bamboo chopsticks and forks. The picnic of new human beings is no longer a lot of pots, pans, knives and forks.

Ruler-can be used to measure the surface soil quality and soil thickness. There is a fork like a fork in front, which is a hook unloader.

It is usually dangerous to remove the metal hook by hand, and this tool can solve the problem safely without much effort.

Saber maintenance

After an outdoor activity, the inner groove of the folding handle holding the blade will always hide the filth and shelter the filth. Although cleaning is very troublesome, if you want your precious knife to work normally next time, please follow the following steps and take the time to clean it carefully!

1, wash with warm water, add some detergent or soap powder, carefully wash the salt, grease and dirt on the tools thoroughly, and then wash them with clean water.

2. Wipe clean with a cloth, wipe the cutter with a soft cloth, wrap a thin bamboo stick or cotton swab with a cloth to thoroughly wipe the details, or directly wipe with a cotton swab. Finally, you can use a hair dryer to blow with cold air to ensure complete drying.

3. Inject lubricating oil into the rotating shaft, and finally ensure that the tool can be unfolded when it is used next time for lubrication; In principle, it is suitable for lubricating oil used in precision machinery, and WD-40, the most common rust removal lubricant on the market, can also be used. Don't overdo it when refueling. If it is contaminated by a non-rotating shaft, it must be wiped clean to avoid cutting food with it during activities.

Finally, before engaging in outdoor activities, be sure to check your knives again!

Swiss army knives are generally used for 20 years without grinding. If the knife is damaged or not sharp. Be sure to use special equipment, or directly ask dealers and agents for help. Use a special whetstone to grind the tool in one direction, not in the opposite direction. In addition to the above suggestions, you can also choose sewing machine oil (the oil must be extremely thin) and gun oil (because I like knives, I can get some from time to time). The biggest advantage of this oil is that it doesn't matter if you eat it. You don't have to worry that too much oil will cut into food.

Finally, before engaging in outdoor activities, be sure to check your knives again!

Special attention: Knives coming back from the seaside must be wiped, treated and oiled with clean water. Seawater is extremely corrosive, and the rotating parts left in the tool will affect the normal use!

Tool grinding and maintenance

Using polished steel is a good way to maintain knives, especially the commonly used straight handle knives, such as kitchen knives. Regular use can keep the blade sharp.

Experts suggest that tools should be polished frequently during frequent use, at least once before and after each use. In fact, grinding steel does not really sharpen the blade, but corrects and cleans the edge of the tool.

One of the most basic polished steels is a metal bar with a handle, and straight grooves are distributed on the metal bar. The polished steel is magnetized, which can attract the molecules of the cutter and rearrange them in a straight line. The steel after tool friction polishing can be corrected and some tiny scratches can be eliminated. Unmagnetized ceramic polished steel also has this effect. As a new trend, diamond polished steel is becoming more and more popular in kitchen utensils. Its surface is covered with a layer of single crystal diamond, which has the same good effect as traditional polished steel, but it is more durable, lighter and faster than traditional polished steel.

When using polished steel, the blade touches the top of polished steel at an angle of 20 degrees, and then the whole blade gently strokes the whole polished steel to the bottom, as if cutting a polished steel with a knife. Every time, the front and back are polished alternately, so that both sides of the blade are polished evenly. A simple way to judge whether a tool has been polished is to gently touch it with your thumb along both sides of the blade. If both sides feel the same, you have polished it. If one side feels slightly rougher than the other side, then gently polish this side, comparing each time until both sides feel the same.

Polishing tool using natural grindstone

First, we list the types of natural grindstones that can be used for grinding and their particle size equivalents (grinding capacity):

Waxita stone)-looks like marble, and its particle size equivalent is 300-350. A good rough stone can remove small scratches and form an inclined outline.

Hard Arkansas)-white or light gray, the particle size is equivalent to 500-600. Used to perfect the edge at the end of grinding.

Black hard Arkansas)-black or dark gray, and its particle size equivalent is usually 800- 1000. It is a very good polishing stone, which can be used to polish sharp blades. Over the years, this kind of stone has been almost exhausted, and only a few places still produce this kind of stone. This kind of stone is generally not needed for sharpening knives. At first, only people who used folding razors liked to use it to sharpen their knives.

Generally speaking, we choose a tile stone and a hard Arkansas stone as natural grindstones, and the size of the grindstone depends on the length of the blade. For example:

Portable knives -3-5 inch long grindstones

Hunting knife -4-8 inch long grindstone

Chopper -6-8 inch long millstone

The use of sharpening oil can prevent tiny metal chips from being embedded in the grindstone. Don't use ordinary lubricating oil, it will block the concave hole of the grindstone. When sharpening a knife, the contact angle between the blade and the grindstone is the most difficult part to grasp. Lay the knife flat on the grindstone, and then slowly lift the back of the knife until the inclined plane of the blade is parallel to the surface of the grindstone. Lifting it too high will blunt the blade, and lifting it too low will not sharpen the blade. You can try a 20-degree angle grinding. When grinding, cover a lot of sharpening oil on the grindstone, and do not dry grind it, because metal chips will be scraped off and embedded on the surface of the grindstone, damaging the grindstone and the blade. Start rough grinding with Washtar grindstone, with the blade facing the grindstone surface and the back facing yourself, so that the knife surface forms a 20-degree angle with the grindstone surface, and then push the knife forward as if to cut a small piece from the front end of the grindstone. Repeat this action 2-3 times from bottom to top, then reverse the knife so that the blade faces you, and then polish it at an angle of 20 degrees with the grindstone surface for the same number of times. Pay attention to grinding both sides the same number of times. When this grinding process is completed, you can get a clear bevel line, so you can prepare for the final grinding process. We use hard Arkansas grindstones for fine grinding. Similarly, we need to apply a lot of sharpening oil to the surface of the grindstone and repeat the rough grinding until you get the sharpness you expect, so the grinding is completed.

Please note that the grindstone should be cleaned with cloth after each grinding, and once a year, you should thoroughly clean the grindstone with special solution and wire brush to make the holes in the stone clear and clean. Remember: a blunt knife is more dangerous! In fact, a knife with a perfect sharp blade is safer than a blunt knife, because it is easy to cut, and you don't need to exert great strength or look clumsy at work, so it is more efficient. No matter how expensive and exquisite the tool is, it is impossible to keep yourself sharp, so you must regularly polish and maintain the blade to keep it in the best condition.

Use DMT diamond whetstone polishing tool.

First, put a little water on the diamond surface of the sharpener, so that the back of the knife is facing you. The blade contacts the surface of the abrasive tool at an angle of 20, and pushes the knife from one end of the abrasive tool to the other. For example, turning the blade from side to side.
