Title: Zippo
Content:  Zippo wicks contain a weaving of thin copper wire which provides physical stability but also acts as a heating element for the fuel source as the flame burns. The heat warms up the lighter fluid increasing its vapor output. A Zippo lighter in colder conditions may hesitate to ignite and give off the impression that it is exhausted of fuel due to the lighter fluid condensing, multiple strikes of the flint wheel maybe be required and once the flame is established it will usually start off smaller and grow as the fuel vapor stabilizes. Over fueling as well as little or no fuel can cause ignition problems. An overfilled Zippo lighter can also build up too much fuel vapor within the chimney while the lid is closed, this reduces oxygen supply to the wick. A brief flashover can occur upon striking the flint as the excess vapor is burned off.

Content:  modern Zippos, not on older models prior to late 1992) are the words, "LIFT TO FILL," to indicate one must lift the felt away from the "cotton" in order to refuel it. The fuel, light petroleum distillate or synthetic isoparaffinic hydrocarbon (commonly referred to as lighter fluid or naphtha), is poured into the rayon balls (sometimes called the "cotton," or the "batting"), which absorbs it. It also contains a tube that holds a short, cylindrical flint. The tube has an interior spring and exterior cap-screw that keeps the flint in constant contact with the exterior flint-wheel. Spinning this rough-surfaced wheel against flint results in a spark that ignites the fluid in the wick. All parts of the lighter are replaceable. The Zippo lighter requires 108 manufacturing operations.

Content:  an easily recognizable "clink" sound for which Zippo lighters are known, and a different but similarly recognizable "clunk" when the lighter is closed. This noise is produced by the spring-loaded toggling cam, a little lever that keeps the lid closed or opened securely. Unlike disposable lighters, newly purchased Zippo lighters do not contain fuel. Instructions for safely fueling the Zippo are included in its packaging. Zippo also offers for sale a name brand lighter fluid. In the United Kingdom other brands of universal lighter fluid can be used instead of Zippo branded. These other brands include Ronson, Swan and Clipper, alternative brands of wicks and flints also exist. The availability will vary by country.
Title: Zippo
Content:  Zippo lighters, which have gained popularity as “windproof” lighters, are able to stay lit in harsh weather, due to the design of the windscreen and adequate rate of fuel delivery. A consequence of the windproofing is that it is hard to extinguish a Zippo by blowing out the flame. However, if the flame is blown from the top down, it will be easily extinguished. The proper way to extinguish the lighter is to close the top half, which starves the flame of oxygen, but unlike other lighters, this does not cut off the fuel supply. One of the recognizable features of Zippo is the fact that it burns with a wick. Opening the top lid

Thousands of different styles and designs have been made in the eight decades since their introduction, including military versions for specific regiments. Zippo lighters have been sold around the world and have been described as "a legendary and distinct symbol of America". In 2012, the company produced the 500-millionth unit.

Content:   The cases of Zippo lighters are typically made of brass and are rectangular with a hinged top. On most models, the top of the case is slightly convex. Inside the case are the works of the lighter. The insert contains the spring-toggle lever that keeps the top closed, the wick, windscreen chimney, flintwheel, and flint, all of which are mounted on an open-bottom metal box that is slightly smaller than the bottom of the outer case, and into which it slips snugly. The hollow part of the interior box encloses five rayon balls (similar to cotton balls) which are in contact with the wick. The bottom of this is covered by a piece of felt approximately 1/4 of an inch thick. Printed on the bottom of the felt

Content:  a chimney cap with holes in it to make it more windproof. The Zippo lighter and company were invented and founded by George Grant Blaisdell in 1932. The Zippo was noted for its reliability, "Life Time Warranty" and marketing as "Wind-Proof". Most early Zippos used naphtha as a fuel source. In the 1950s, there was a switch in the fuel of choice from naphtha to butane, as butane allows for a controllable flame and has less odour. This also led to the use of piezoelectric spark, which replaced the need for a flint wheel in some lighters and was used in many Ronson lighters. In modern times most of the world's lighters are produced in France, the United States, China, and Thailand.

Edwards stated: "when you say level a village, you don't use torches. It's not like in the 1800s. You used a Zippo. Now you would use a Bic. That's just the way we did it. You went in there with your Zippos. Everybody. That's why people bought Zippos. Everybody had a Zippo. It was for burnin' shit down." "Zippo squad" became a phrase of American military jargon for being assigned to burn a village. The M132 Armored Flamethrower was referred to as a "Zippo".
