First of all, look at the appearance. There is a circular concave mark on the upper and lower joints of the genuine Zippo lighter. The two circular marks on the hinges on the casing are indeed difficult to make exactly the same on imitation machines. It can also be used as a basis for judgment. The bottom of the Zippo has the year of manufacture. From 1932 to 1956, it was written in block letters; from 1957 to 1976, it was written in italics; from 1977 onwards, the trademark shape with a flame pattern was used. In addition, starting in 1957, the base of all ZIPPO lighters has been engraved with a mark representing the year of manufacture to facilitate collectors' identification. Products before this can only be identified by S number or design type. There are four types of symbols representing the year of manufacture, namely [·] (used in 1957), [ | ] (used from 1966-1973), [ / ] (used from 1974-1981) and [ \ ] (used from 1982-1986 use). Each mark is used for 8 years. There can be a maximum of 8 of these marks, engraved on the left and right sides of the ZIPPO trademark (ie, a maximum of 4 on each side). And adopt the method of decreasing year by year, at least there is only 1 left. Beginning in 1986, in addition to the year, month symbols were added. The Roman numerals on the right side of the trademark represent the year of manufacture (II stands for 1986, III stands for 1987, and IV stands for 1988); the English letters on the left stand for the month of manufacture (A stands for January, B stands for February, and C stands for March). Among the above characteristics, fake Zippo lighters generally lack or are incomplete, and the printing is also rough. The performance, quality, and appearance are all incomparable to the real Zippo. In addition, we can also compare the actual use of real and fake Zippo. First: Weight: Genuine Zippo lighters are generally lighter than counterfeit ones. This is because fake Zippo lighters are made of steel or iron materials, not Zippo-specific materials; some unscrupulous manufacturers increase the thickness in order to pursue a harder shell. Second: Check the flame and heat resistance. Zippo counterfeit products emit green smoke when burning, and the flame flickers on and off. The entire fuselage is completely burned within 4 minutes of burning. A real Zippo lighter will burn until the fuel is exhausted and will not ignite the fuselage. This is because the fake Zippo steel outer cover is too thick and has poor heat dissipation effect; the oil storage cotton core inside the machine is of poor quality and is prone to oil leakage. Third: Windproof ability. Place the real and fake Zippo 40 cm away from the electric fan and turn the fan to the maximum wind power. The flame of the real Zippo lighter still cannot be extinguished. The fake Zippo lighter was blown out when the electric fan was only turned on the minimum wind power. This is because the windproof wall of real Zippo lighters is high; the design of the vents is scientific and reasonable; and the special fire core absorbs oil well. There are many styles of zippo. I personally think that most mature men will like more personalized styles. I bought a zippo with gray and black matte surface for my father as a birthday gift. After using it for many years, the quality is still very good. Black is a very mature and charming color, and the matte surface looks very classy. I think this style is very suitable for older men. If you are a young office worker, around 30 years old, you can choose a style with brighter colors to highlight your personality without losing stability. There are various patterns printed on many Zippo. It depends on the style of clothes the person you want to give, hobbies, and personality. Combining these factors, you will definitely be able to choose a lighter that is absolutely suitable for him. Finally, I would like to introduce you to Zippo’s official website.
