A Short History of the Swiss Army Knife

The story begins in 1891 with Karl Elsener, owner of a company that made surgical equipment. He founded the Association of Swiss Master Cutlers, to supply pocket knives to the Swiss army, who at this time were using German-made ones. It took Elsener five years to come up with what he called the "Soldier's knife" (known today in Switzerland as the "Offiziersmesser"). With suggestions from an engineer friend, Jeannine Keller, the original model had a wooden handle, and came with a blade, screwdriver, can opener, and a punch. It was actually made available to the army before 1896, but Elsener was not happy with the device, and eventually was able to put blades on both sides by using a special mechanism using a single spring for both blades. This allowed him to also add a corkscrew.

Elsener's company, Victorinox, was the single supplier of multi-function pocketknives until 1893. A company in the French-speaking area of Switzerland called Paul Boechat & Cie began to market a similar product. The company was later bought by its general manager, Theodore Wenger, and the company name changed to Wenger. By 1908, the Swiss government decided to split the contract for knives between the two companies, partly to appease German and French-speaking factions in the country, and partly to stimulate competition (and lower the prices of the knives). The two companies came to an agreement over marketing, with Victorinox using the phrase "The Original Swiss Army Knife" and Wenger using "The Genuine Swiss Army Knife". The following year (1909), the Swiss army began decorating the knives with the Swiss national symbol (a white cross). Victorinox uses a shield with bilateral symmetry around the cross, while Wenger uses a slightly rounded square with quadrilateral symmetry. The Swiss army uses knives with a simpler bilaterally-symmetric shield.

Victorinox switched to stainless steel blades and tools in 1921. It is believed Wenger did so as well around the same time, but company sources are inconclusive about the exact date. The knives were sold in PX stores on US army bases from 1945 to 1949. In fact it is believed that the term "Swiss Army Knife" was coined in English by American G.I.s during World War II, because they couldn't pronounce the Swiss name "Offiziersmesser".

Today, Swiss army knives contain a multitude of tools, including: several blades, a bottle-opener/screwdriver/wire stripper, can opener/small screwdriver, tweezers, toothpick, corkscrew, phillips-head screwdriver, nail file, scissors, saw, hook, magnifying glass, ballpoint pen, fish scaler, pliers, keychain, USB flash memory, digital clock, digital altimeter, LED light, laser pointer mp3 player, and a brass spacer in the official army model, which allows assembly of the SIG 550 and SIG 510 assault rifles (with the screwdriver and reamer extended, the knife becomes a restraint to the firing pin during the lock assembly). Wenger has a special model which contains all the tools they make. The device is nearly twice as wide as it is long, and retails for around $1,200.

The knives are also available in many other colors besides the traditional red. Black, blue, white, pink, camouflage, phosphorescent yellow and many others, in both opaque or transparent. Also metal and wood cladding. The model actually used by the Swiss army is in fact aluminum, and not red at all.

On April 26, 2005, Victorinox acquired the Wenger company, becoming again the single supplier of knives to the Swiss army. The company intends to keep the Wenger brand alive for knives sold to consumers.

Green Laser Pointer Attracts More and More Young People in US

I heard over 5mw green laser pointers are prohibited in US and Australia, but one can see American and Austrialian people holding green laser pointers nearly everywhere. I came to realize that it’s just illegal to purchase or produce high powered laser at home, while they have the greatest freedom to purchase it from abroad, esp. China, a laser power country. That also can explain why Laserto.com and Highlasers.com are winning more popularity in US, England, France and Germany.

I once wondered why so many over 40 ys old male in US are so crazy about green laser pointers, but the fact that some well-known laser companies such as Laserto.com states that 75% of their customers are 35-45 age group. The 2007 survey set by Laserto.com proves that 65% of this group are just for entertainment uses, such as use a green laser to burn stuffs, pop balloons, cut plastic tapes, light matches or light cigarettes, or simply holding this amazing gadget makes them feel young and refreshed by the laser beam. 20% of the people use it for more pro uses, such as for astronomical, military, or medical uses(some use it for better dental treatment, some for acupuncture,ec.)For this group, Gehenna series 200mw green laser is their favorite used laser, for this high-end and high-powered laser can enable them to do what they want for both dummies and pro uses.

A survey by Laserto.com this year reveals that green laser pointer is eyeing for the kids market, coz some kids green laser lovers say, they clamour for green laser pointers because they make them feel cool and grown-up .That’s true.

The report shows that 15% of youngsters aged 16-25 now use laser pointers.

Improving your Air Quality With an Air Purifier

Did You Know?

According to a 2002 survey by the American Lung Association and 3M, the Environmental Protection Agency (EPA) ranks poor indoor air quality among the top five environmental risks to public health. Interestingly enough, five out of ten Americans are not aware of this fact.

Indoor air quality (IAQ) has greatly deteriorated over the years due to stringent laws enacted during the 1970s in response to energy shortages throughout the nation. As a result of these conservation efforts, homes and offices alike have been constructed to be air-tight, therefore trapping dangerous pollutants such as dust, pollen, gases, and microorganisms into homes and offices. Because of this, indoor air is contaminated, and this, in combination with the fact that Americans are now spending up to 90% of their time indoors, has resulted in an alarming increase in symptoms associated with asthma, hay fever, and other respiratory problems.

Indoor exposure to contaminants in the workplace, tobacco smoke, mold and biological pollutants, hospital pollution, and pet dander and odors can trigger disorders like multiple chemical sensitivity (MCS), as well as asthma and allergies.

In fact, exposure to airborne particulates is one of the primary triggers for asthma attacks. Indoor air pollutants have also been shown to cause and exacerbate symptoms such as eye, nose, and throat irritations; headaches; fatigue; and dizziness. Long-term exposure to such pollutants can even cause heart failure, cancer, and other severe, debilitating, and/or even fatal diseases. Because of this relatively recent evidence showing the effects of indoor air contaminants, air purifiers have become increasingly popular for both home and commercial use. Even the EPA has noted that air purifiers and cleaners are an effective way to remove particles and pollutants from indoor air.

Consequently, with this increased interest in air purification technology, there has been a surge of air purifiers flooding the market, and choosing an effective air purifier may seem like a daunting task. With several air purifiers utilizing technologies such as HEPA filtration, ionization, ozone, and ultraviolet (UV) light, it is not surprising that many consumers may feel overwhelmed when shopping for an air purifier.

Generally, air purifiers clean the air by any one of these three ways or by a combination of these methods: by attracting and collecting particulates using either mechanical or chemical filters, by emitting ions via an ion generator to charge and attract particles, or by passing airborne particles through a UV lamp to change the DNA of microorganisms, which render them harmless and unable to reproduce. When deciding on an air purifier, it is important to choose a purifier with a filtration system that is designed for your specific problem, such as allergies, pet dander, tobacco smoke, or mold/mildew. As well, the noise level of an air purifier, the energy the purifier consumes, and the square footage of the area being purified should also be considered.

Whether you're an asthmatic looking to decrease the amount of dander in your home, or whether you need to maintain germ-free air for your clean room, an air purifier can help keep the air you breathe contaminant-free.

Laser Pointer & Portable Laser Safety

Safety with high powered laser pointers is a critical issue that cannot be overlooked. Despite their brilliant beams and ability to burn, high power laser pointers and portable lasers are only a danger to your eyes. The danger that laser pointers represent to your eyes though is very serious. The visual receptors in your eyes are part of your central nervous system which means if our eyes are damaged, they do not heal or recover. Ever.

As far as power output, laser pointers do not release that much power. Especially not when compared to a normal 75mW or 100mW light globe. What makes the light from laser pointers so dangerous is that it has two unique properties.

1-Coherent and focused. The energy is focused on a very small area similar to the way a magnifying glass focuses the sun

2-Collimated. The light does not spread out from a laser, it stays in a focused narrow beam that makes laser pointers almost as dangerous at a distance as close up.

This not to say you should be afraid of laser pointers or avoid using them. What you should do how ever is to treat laser pointers with respect, be aware of their dangers and follow some basic guidelines to ensure your safety.

Guidelines 1- Never point your laser at another person, especially their face.

2- Never under any circumstances look directly into the laser beam. Even if it is a low powered laser pointer, you don’t want to take chances with your eyes

3- Always be conscious of and aware of reflective surfaces such as mirrors, polished metal or glass. A reflected beam can also harm your eyes.

4- Only use laser pointers in a controlled environment

5- Do not let other people use your laser pointer unless they are fully aware of the dangers of laser pointers

6- Laser pointer beams can go for miles so never randomly use your laser pointer outside

If you adhere to these guidelines and exercise simple common sense and care, you will be able enjoy and use your laser pointers in complete safety.

Presentations And Lectures Will Surely Benefit From Having A Green Laser Pointer

In today’s marketplace, lasers have a lot of practical uses, including working as a pointer for presentations and lectures. Green lasers are a type of laser pointer that became available around the year 2000. These green lasers fall under the class of DPSS lasers, or diode pumped solid state lasers. Traditional red laser pointers are not all that complex. Compared to those, green lasers have a much more intricate state of complexity.

Presentations and lectures will surely benefit from having a green laser pointer, especially if the presentation uses a projection screen or other visual aid. Green lasers have a wider range and are often used to highlight certain key points. Where ever the green dot is, the eye will follow. It is a way to keep the person listening engaged in the discussion and what is going on.

It is a way to keep the person listening engaged in the discussion and what is going on.

If you need to purchase a laser pointer you have several options. They come in red, green, and blue. But green lasers are a good choice because of how new they are. Some manufacturers are also starting to sell blue lasers and these are very similar to green lasers. But green lasers are currently a little more common because more manufacturers are making them.

There is a serious benefit to green lasers of their older red lasers. Green lasers are more versatile than their older cousins. Green lasers can be used at longer ranges and also outdoors. This means that they can be used on outdoor projects and presentations as well in situations like at construction jobs. Imagine this scenario: the supervisor wants something to get done. Instead of pointing or physically walking over to the spot that needs attention, he or she can u se the green laser pointer to highlight the areas and give a visual clue to the workers.

When it comes to lasers, green lasers are amongst the most versatile. They can be used both indoors and outdoors. In addition to their many practical uses, they can also be used for fun. Cats and kittens delight in chasing the dot around the room. It makes them crazy knowing that there is something there that they just can’t touch so it makes them go even crazier with it. Since a lot of cats and kittens tend to be indoor animals, giving them reasons to exercise is a good thing.

Buy High Quality laser pointers rather than "Cheap" laser pens

Many laser lovers complain about their defective laser pointer pens purchased online, but they're just out of luck or careless in getting them.

The never-loosing frowns at those "shoddy" lasers gradually ruins the name of all laser products. In order to help global laser lovers find the genuine laser that lasts for years and meanwhile do justice to the decent laser business, we're here to help you tell the "wrong" from the right.

We know it pays to be cutting edge, and to put aside the laser power or beam, one could tell if the laser is "bat out" or really refinedly made from the shell or casing.The shoddy laser pointers' shell are generally made out of  low quality metal or even plastic. Like the Classics series 1 to 150MW green lasers at our site are all of pure aluminum, silver, or special metal hardened/anealled alloys. The special air cooling method has also been adopted. A high powered DPSS laser module usually generates a lot of heat that needs to be dissipated by the shell while the low-end shell will not able to release the heat as easily and the normal function of a laser will be deteriorated. The heat that builds up can even burn out the laser diode.

The laser beam of the green lasers is Always and only green because green light is the most visible color to the human eyes.  However, shoddy green laser pointers do not just give out green light, they also give out infrared light. Infrared light cannot be seen by the human eye so the beam from these shoddy laser pointers is not as bright as it should be and is also most dangerous to the eyes. You can damage your eyes and not even be aware of it until to late. All the laser pointers from LaserPointerPen.Net guarantees the non-IR green laser beam, while the supporting of Infrared (IR) protection 1064nm laser goggles and Near Infrared (IR) 750-850nm protection laser goggles nearly provide a Double Insurance of the eye safety of the eyes. Moreover, we often provide these laser safety goggles for free, esp. for those over 200mw green laser clients.

Many laser retailers cheats their customers on wavelengths, and some confuse the commonplace 433nm blue laser pointer with the 473nm blue laser pointer pen. These years, the 532 nm green laser being the most commonly seen, in September 2005, handheld blue laser pointers at 473 nm have also become available. The portable blue laser pointer is not only related to blue laser, blue laser diode, blue laser sight, blue laser power and blue laser module, but also introduces the DPSS laser, laser optics, laser module, laser diode, diode laser, fiber laser, laser power, solid state laser, laser technology, yag laser, laser show, laser light show, laser marking, laser printer, semiconductor laser, eye laser, laser light, laser gun, laser welding, etc.

Some laser lovers are attracted to many shoddy lasers just because they use high powered rechargeable batteries, and that's why most "bulky" all-solid-state laser modules are often neglected. Actually, the high-end laser technology has little to do with the batteries though the power supply counts. On the other hand, even high powered batteries could not make a ultra bright beam as it should be if it happens to be a shoddy laser.

 

You may be asking why a shoddy laser pointer can have a power of 200mW but be less bright than a 50mW green laser from LaserPointerPen.Net. Here is the trick. As we just said, these laser pointers give out a lot of infrared light which you can't see making them less bright. Laser power meters however cannot distinguish between green light and infrared light. The 200mW power level of a shoddy laser pointer will normally be made up of mostly infrared light. For example a combination 25mW green (532nm) and 175mW infrared (808nm). A 50mW dragonlaser will be 50mW green with virtually no infrared.

So run to genuine lasers from now on and do the laser itself justice!

How Can a Laser Correct Your Vision?

 

Not all lasers could correct your vision. Some could destroy it. There are a great many different types of laser, all man-made for different purposes. The one used for vision correction is called the Excimer laser – a name which means little to anyone except the people who first developed this type of laser. They made the word up, from two other words: excited and dimer. The story as to why is not relevant to the exciting world of LASIK.

Eye surgery, like every type of surgery, has been transformed by lasers. The excimer laser which does Custom LASIK, PRK, IntraLase, LASEK, and epi-LASIK procedures comes as part of a system of sophisticated technology and is a major investment for the eye surgeon.

How is a Laser Different From Other Lights?

Laser lights:

· Travel in rays that are parallel to each other;

· Are directional; and

· Have a single vibration.

Lasers are focused lights, rather than scattered like headlights or flashlights. That is why they make good classroom pointers. It’s also why they are excellent for eye surgery, because they can be made to come to a microscopically tiny focus.

Lasers and Heat

All lights generate heat and all hot things give off light. Light and heat are two aspects of the same energy. Some lasers are so hot they can slice through a block of steel. Some lasers used in dentistry and medicine are referred to as “cool” lasers, and the excimer laser is one of those. Cool lasers are both inherently cooler than some other types of laser, and also deliberately cooled for medical use.

Lasers and Color

Since all lasers have just one vibration level, they are a single color. Some have visible colors and some are infrared or ultraviolet – their vibration is beyond our visible color spectrum. Excimer lasers are ultraviolet.

How the Excimer Laser Works

The total vision correction system containing the excimer laser includes a patient bed, a computer and monitor, a tracking device to keep the laser targeted on each eye’s treatment area, a microscope for the eye surgeon to see your eyes highly magnified, a seat for the surgeon, and some tools and implements.

By the time you are on the patient bed for your vision correction, your two eyes have been precisely diagnosed as to their refractive errors. That is the first part of a Custom LASIK surgery, done before the day of your treatment. Your treatment plan is based on two 3-D maps generated by the diagnostic Wavefront equipment. They are microscopically exact maps of each eye’s contours and shape.

The excimer laser is programmed to follow these two maps during treatment, subject to your eye’s surgeon’s control. First a thin flap of surface tissue is folded back on the cornea (front transparent part of the eye), to expose the next layer down, the stroma. Then the excimer laser is directed on the pre-determined treatment area, and quickly vaporizes tiny pieces of unwanted tissue, at pre-set depths.

A New Corneal Contour

Your eye doctor planned the tissue vaporization so as to reshape the cornea. The cornea bends (refracts) light entering the eye, and in a 20/20 eye focuses it on the retina (“camera film”) at the back of the eye. Modifying its curvature changes the cornea’s degree of light refraction.

· If you are nearsighted (myopic), your eye surgeon will use the excimer laser to remove pieces in the center of the cornea. That slightly flattens the corneal curvature, and now light will not be refracted quite so much. You will have clear distance vision.

· If you are farsighted (hyperopic), your eye doctor will remove tissue from the periphery of the cornea, to slightly steepen its curvature. Now light will be refracted a bit more and you’ll have clear close-up vision.

· If you are astigmatic, your eye surgeon will remove tissue in an individual way according to your eye’s particular oval shape, to create a more round shape. An astigmatic eye is like a football, with a lengthwise flatter curvature and a crosswise steeper curvature. After it is made round, light will be refracted in only one way instead of two.

Lower and Higher Order Aberrations

No treatment plan is as simple as the above makes it sound. Many people are both astigmatic and myopic, for instance; and we all have tiny imperfections called Higher Order Aberrations. They are subtle defects like halos around light sources, poor night vision, and ghosting – faint duplicate images.

Myopia, hyperopia and astigmatism are the three Lower Order Aberrations. Custom LASIK corrects both higher and lower order aberrations. That allows you to (a) see more, because you have clarity at all distances; and (b) see better, because none of those subtle defects get in the way.

If you are considering a LASIK procedure, the best thing you can do to obtain excellent results is to choose a well-qualified eye surgeon. The best LASIK surgeons screen their patients very rigorously because it is in nobody’s best interest to perform a procedure on somebody who is a poor candidate for it. So do some homework before you choose your LASIK surgeon, and choose one who has many years of experience and has done several thousand procedures of the type you need.

Hair Removal Laser Equipment

People tend to fear what they do not understand, and there is perhaps no more misunderstood technological advancement in the past couple of decades than lasers. When we think of lasers, our imaginations go wild with all kinds of sci-fi and fantasy visions. Lasers cutting people open, a la James Bond in Goldfinger. Lasers used as futuristic weaponry like lightsabers and blaster pistols in Star Wars. Lasers even make us think of new weaponry projects like the missile defense system currently being constructed.

For some reason, lasers have a certain bond with death and destruction - a problematic assumption that laser hair removal equipment manufacturers and specialists have to deal with day after day.

However, not all lasers are bad. Take laser pointers, for example. These are low wattage, completely harmless beams of light that are emitted from a device powered by a lowly battery. Those lasers certainly aren’t capable of slicing people in half or shooting down missiles. And so is the case with laser hair removal equipment. Such devices are completely harmless and are designed for one purpose and one purpose only - to remove unsightly or bothersome hair anywhere on your body.

Instead of simply telling you that the laser hair removal equipment that will be used during a laser hair removal procedure is completely harmless, let’s present some facts about hair removal with the use of lasers instead. The laser, almost always based on a ruby or another mineral known as alexandrite, shoots a beam of light that is not powerful enough to damage your skin but is perfect for destroying the hair follicle and the hair bulb - preventing hair growth in areas hit by the laser. This laser, through excellent targeting and low power consumption, simply cannot damage a person’s skin - no matter how long it shines on the same spot.

Now compare the laser hair removal equipment used by laser hair removal specialists to other kinds of hair removal techniques. Previously, one of the most effective ways to remove hair was by using a sort of hair removal cream. You’ve probably seen these products advertised on television as “completely harmless.” But why would you want to rub a cream on you, made of unknown and unpronounceable chemicals, that makes your hair fall out and not return for months on end. It could be anything in those products - even chemicals that are dangerous or deadly when used for prolonged periods of time.

Compared to the harmless laser hair removal equipment that modern hair removal specialists are now using, the choice seems clear. Why would you risk your life using a hair removal cream when you could simply visit a laser hair removal specialist and receive a treatment that is totally harmless and uses only the newest, most high tech equipment available. There is simply no reason to fear the new laser hair removal equipment when what you should have been fearing all along was the pain of waxing and plucking, the harsh chemicals used in various hair removal creams, and the cost of purchasing drugstore hair removal product after drugstore hair removal product because none of them worked as well as advertised.

Capacitive Sensors are Hot Topic Today

From touch screens in cars, touch screens at the bank and on your phone, more and more touchable screens and other devices are coming on the market using capacitive sensors.

 

What is Capacitive Technology?

A capacitive touch screen panel is coated with a thin indium tin oxide material that conducts continuous electrical currents across a sensor- say a touch screen of an iPhone. So it exudes a controlled electronic field in both a vertical and horizontal axis and therefore is capacitive. In order for the capacitive technology to function, it must be touched by something else that also exhibits electricity- like the human body. When a person’s finger touches a capacitive screen, it sends an electric current to then form a mathematical function which signals an action. Then, you suddenly get an image, make a payment or access your GPS system all at your fingertips. But why capacitive touch technology over other forms?

 

Capacitive sensor technology is the pricier cousin on resistive touch technology but capacitive technology delivers a better product. But, resistive touch panels are less expensive and have a shorter lifespan than capacitive panels. Most everyone has used a resistive touch screen panel without knowing it and a huge majority of us have used resistive technology today either with our fingertips or with a stylus pen when buying a shirt at the mall or even a pack of gum at a convenience store.

 

Capacitive technology’s sudden populatiry could be due to Apple’s successful iPhone. The world got hooked on the touch screen technology and manufacturers began looking to capacitive sensor technology more seriously. If consumers would pay for a better product, then it would be worth the investment, This increased manufacturing of capacitive panel makers, making the capacitive panels less expensive then previously priced. Technology sources believe it could soon be the mainstream touch panel model.

 

 

Could The Age Of The Computer Mouse Be Eliminated?

What happens to everyone’s computer mouse if everyone’s computer screen suddenly becomes touchable? All computers, laptops and hand held PDA’s will soon be touchable and therefore eliminate the need for a computer mouse to maneuver a pointer to access controls.

 

Less is more when it comes to developing marketable technologies. For example, the size of new technology is constantly shrinking, minus huge plasma televisions, but cell phones, laptops and portable devices for accessing the internet are all shrinking. People want MP3 players that fit on their ear or in a shirt pocket. People want Blue Tooth head sets and simple and clean technologies. Therefore, eliminating the computer mouse is just another way technology is getting sleeker and smaller and delivering greater performance.

 

Besides all of the time saved using touch screens, there are so many other reasons touch technology is booming:

 

• Reduced paper use, like checks
• Compact and simple
• Eliminating the computer mouse, which removes a lot of chronic injuries
• Efficient
• Instant database storage capabilities

 

How many touch technologies have you used today? How many more will you use once the day is out? People are not just talking about these technologies, they are using them too.

Shoddy green laser pointer – What to Expect

Working in the field of lasers, I met a lot of complaints from buyers all over the world about shoddy green lasers. To help customers understand the dangers of shoddy laser pointers and clear up some misunderstandings that have laser sloppy information below.

Infrared (IR) light green (532nm wavelength) is the color most visible to the human eye and any green laser you buy should be light green and ONLYgreen light. Our Viper laser pointers and Hulk portable lasers, for example, only 532 give the green light. Laser poor even if given the green light and infrared dangerous (IR) light. Infrared light can not be seen with the naked eye so the beam of these shoddy laser pointer is not brilliant as it should be and is also very dangerous.

You might wonder how a shoddy laser pointer laser, but may have a power of 200mW, less Brilliant 55MW ViperPointer. Here is the trick. As we said, these laser pointers give an amount of infrared light, you can see that makes them less bright is not enough. Line laser measuring devices is not easy to distinguish between green light and infrared radiation. The transmit power of a 200mW shoddy laser pointers are typically infrared light, composed of everything. For example a 200mW shoddy laser pointer is probably a combination of infrared 25mW green (532nm) and 175mW(808nm). A Viper laser pointer 55MW 55MW green lights are virtually infrared light.laser pointer green

All genuine green laser pointers and portable lasers have infrared filters inside that block infrared light. Shoddy laser pointers have this filter removed. Without this filter, laser pointers are very dangerous because the infrared light can damage eyes and you would not even be aware until it is too late.laser pointer green

So if you have aHigh-power laser pointer that is not brilliant, it is likely that many IR dangerous as this, you use it with extreme caution, or better yet, destroy it.laser pointer green

cases of poor quality / shells

Another problem with laser pointers is their sloppy case or shell. Their skin is often of poor quality standard metal or plastic. High-performance DPSS laser module generates much heat that Shell should be removed from the file. If ShellPoor quality material, the heat of the laser can be released and not very fast build. This will cause the accumulation of the burning heat of the laser diodes, which completely destroyed the tank Both Viper laser pointers and Hulk portable laser diode laser from a metal alloy, the laser is very effective in heat dissipation and protection. If a 95mW Viper laser pointer is 60 worked forSecond, the hand can feel the heat has been released from the shell as a laser is kept cool -laser pointer green

Why Give Away Wholesale Key Chains for Promotional Giveaways?

When a company has a promotional giveaway, the powers that be often think that they need to have a big product to give away or their customers will not want what they offer. This is not the case. The truth is that something as simple as wholesale key chains can be an effective way to promote your company to customers through a promotional giveaway. With simple promotional items, you reach your customers effectively and you save money while doing so. For example, let's look at two scenarios involving promotional items.

If you give away a television with your company logo on it, you spend $500 for the product and one customer gets it. That one customer can show off the television and they will probably be in the paper. This means your company reaches about 200 to 300 people thanks to the promotion of the product and the people who see the product at the customer's home.

Now, say instead you give away 100 five dollar wholesale key chains. Now, you have reached 100 people, all of whom use their key chain for years. They won't be in the paper, but if an average of 100 people per person sees the key chain and your company logo on it, then 100 key chains reach 10,000 people. So, for the same price, but with more quantity and less price, you reach 10,000 people instead of only 200 to 300. That means a lot more promotion and a lot more companies who feel loyal to your company. The one customer who wins the television will keep shopping with you. However, those who lost may not. Now, with wholesale key chains you have 100 people who will keep shopping with you, earning your company thousands of dollars in sales thanks to a five dollar key chain.

Wholesale key chains may seem like a simple gift for your customers that won't yield many results, but the truth is that it will. It will yield a massive amount of results for you thanks to the quantity of customers you can reach. You can even have your key chains engraved or include a laser pointer on them to make them more appealing to customers. This costs more, but you will have a better chance of a customer using the key chains with the more features you put on them.

If you are going to have a promotional give away, then don't go with promotional gifts that are expensive and can only be given to a few customers. You will want to give your customers something small so you can reach more customers and wholesale key chains can do exactly that for you. They are effective and easy to distribute. Plus you can put your company's name on the key chain and be able to reach even more customers thanks to those customers seeing your company name on the key chain. Sometimes big isn't always the best, and this is the case with promotional items and promotional giveaways.
