A razor is a bladedtool primarily used in the removal of unwanted body hair through the act of shaving. Kinds of razors include straight razors, disposable razor, and electric razors. While the razor has been in existence since before the Bronze Age the oldest razor like object has been dated to 1. B. C. 2, the most common type of razor in current usage is the safety or electric razor, though other kinds are still in use. HistoryeditRazors have been identified from many Bronze Age cultures. Agilent Lab Advisor. These were made of bronze or obsidian and were generally oval in shape, with a small tang protruding from one of the short ends. Various forms of razors were used throughout history, which are different in appearance but similar in use to modern straight razors. In prehistoric times clam shells, shark teeth, and flint were sharpened and used to shave with. Drawings of such blades were found in prehistoric caves. Some tribes still use blades made of flint to this day. Excavations in Egypt have unearthed solid gold and copper razors in tombs dating back to the 4th millennium BC. Several razors as well as other personal hygiene artifacts were recovered from Bronze Age burials in northern Europe and are believed to belong to high status individuals. The Roman historian Livy reported that the razor was introduced in ancient Rome in the 6th century BC. Lucius Tarquinius Priscus. Priscus was ahead of his time because razors did not come to general use until a century later. The first modern straight razor complete with decorated handles and hollow ground blades was constructed in Sheffield, in England, the centre of the cutlery industry, in the 1. Benjamin Huntsman produced the first superior hard steel grade, through a special crucible process, suitable for use as blade material in 1. England. Huntsmans process was adopted by the French sometime later albeit reluctantly at first because of nationalist sentiments. The English manufacturers were even more reluctant than the French to adopt the process and only did so after they saw its success in France. Sheffield steel, a highly polished steel, also known as Sheffield silver steel and famous for its deep gloss finish, is considered a superior quality steel and is still used to this day in France by such manufacturers as Thiers Issard. In the 1. Daily shaving was not a widespread practice in the 1. The custom of shaving every day among American men is a 2. World War I. Men were required to shave daily so their gas masks would fit properly and this became much easier with the advent of the safety razor, which was standard issue during the war. In the 1. Sheffield, England and Solingen, Germany produced a variety of razors. Razor made of bronze from the first Iron Age. Straight razors were the most common form of shaving before the 2. Barbers were specially trained to give customers a thorough and quick shave, and a collection of straight razors ready for use was a common sight in most barbershops. Barbers still have them, but they use them less often. Straight razors eventually fell out of fashion. Their first challenger was manufactured by King C. Gillette a double edged safety razor with replaceable blades. Gillettes idea was the use of the loss leader concept, in which the razors were sold at a loss, but the replacement blades earned a high margin and provided continuous sales. They were immensely successful because of advertising campaigns and slogans denigrating the straight razors effectiveness and questioning its safety. These new safety razors did not require any serious tutelage to use. The blades were extremely hard to sharpen, and were meant to be thrown away after one use, and rusted quickly if not discarded. They also required a smaller initial investment, though they cost more over time. Despite its long term advantages, the straight razor lost significant market share. And as shaving became less intimidating and men began to shave themselves more, the demand for barbers providing straight razor shaves decreased. In 1. The first such blades were made by the Wilkinson firm, famous maker of ceremonial swords, in Sheffield. Soon Gillette, Schick, and other manufacturers were making stainless steel blades. These were followed by multiple blade cartridges and disposable razors. For each type of replaceable blade, there is generally a disposable razor. In the 1. 93. 0s, electric razors became available.

Straight razorsedit. A straight razor manufactured by DOVOStraight razors with open steel blades, also commonly known as cut throats, were the most commonly used razors before the 2. Straight razors consist of a blade sharpened on one edge. The blade can be made of either stainless steel, which is slower to hone and strop, and holds an edge longer, or high carbon steel, which hones and strops quickly, but has a less durable edge. At present, stainless steel razors are harder to find than carbon steel, but both remain in production. The blade rotates on a pin through its tang between two protective pieces called scales when folded into the scales, the blade is protected from damage, and the user is protected. Handle scales are made of various materials, including mother of pearl, celluloid, bone, plastic and wood. Once made of ivory, this has been discontinued, although fossil ivory is used occasionally. Disposable blade straight razorsedit. A simple shavette razor with disposable blade inserted. These razors are similar in use and appearance to straight razors, but use disposable blades, either standard double edged cut in half or specially made single edge. These shavettes are used in the same way as straight razors but do not require stropping and honing. Although the blades of disposable razors wear quickly, useful blade life can be extended with proper care, including drying the blade after use. Safety razorseditThe first safety razor protected the skin from all but the very edge of the blade and was invented in 1. Frenchman, Jean Jacques Perret,1. Perrets design was essentially a straight razor with its blade surrounded by a wooden sleeve. Around 1. 87. 5 a new design with a smaller blade placed on top of a handle was marketed by the Kampfe Brothers1. Removable blade razorsedit. A modern double edged safety razor. The term safety razor was first used in 1. The edge was then protected by a comb patterned on the head to protect the skin. In the more modern day produced safety razors, the comb is now more commonly replaced by a safety bar. There are two types of safety razors, the single edged and the double edged. The single edged razor is essentially a 4 centimetre 1. The double edged safety razor is a razor with a slant bar that can be used on both sides, with two open edges. The blade on the double edged safety razor is slightly curved to allow for a smoother and cleaner shave. In 1. 90. 1, the American inventor King Camp Gillette, with the assistance of William Nickerson, patented a new variation of safety razor with disposable blades. Gillette realized that a profit could be made by selling an inexpensive razor with disposable blades. This has been called the razor and blades business model, and has become a very common practice for a wide variety of products.
