A razor is a bladed tool that people use to shave hair from various parts of the body. There is evidence indicating that razors were in existence before the Bronze Age. Obsidian and bronze were the major materials used to make these tools in most ancient worlds. They were oval-shaped with tangs protruding from the short end. The ordinary razors in use today were invented in the eighteenth century, with electric models coming up in the 1960s.
These products have evolved a lot because of technological advancements. The modern market has a lot of cheap razor blades one can pick from. Some great examples of these products are electric razors, straight razors, and disposable razors. The invention of the various types of razors occurred at different times and they have also evolved differently into what they are today.
Before the advent of the twentieth century, the most common kind of razors were the straight razors, which are also known as cut-throats. These razors are composed of a blade that is sharpened on one edge. The blade is made of two main materials, that is, stainless steel or carbon steel. Stainless steel holds an edge longer and is slower to strop and hone. One the other hand, carbon steel hones and strops faster, but the edge is less durable.
Both stainless and carbon steel razors continue to be manufactured even today. However, those made of stainless steel are rarer. Cut-throats razors revolve between protective scales on pins. The purpose of the scales is protecting skins from being cut and the blade from be damaged when one folds the tool. Bone, mother-of-pearl, wood, celluloid, plastic, and ivory are some of the materials used to make handle scales. However, ivory is no longer used.
Disposable blade straight razors are similar to straight razor in their use and appearance. However, they use disposable blade, which may be single-edged or double-edged blades cut into half. These variants also do not need stropping and honing. The razors also wear out faster, but the useful blade life can be made to last longer through proper care. Care usually include drying the blade thoroughly after use.
Safety razors are designed to protect the skin from cuts from all parts of the equipment, but the edge. Jean-Jacques Perret is credited with inventing it in 1762. Safety razors have similar designs as straight razors, with the difference being that their blade is enclosed in sleeves. The skin is protected by safety bars in modern varieties. Double-edged and single-edged models are the two types of safety blade in existence.
Electric razors also go by the name electric dry shavers. These models have an integral oscillating or rotating blade. They run on tiny DC motors, which derive their power from either batteries or electrical energy from the mains. Water, shaving cream, and soap are not necessary when using these devices.
Invention has led to the development of new electric razors that rely on rechargeable batteries for power. Rechargeable batteries may be alternated with electro-mechanical oscillators that are driven by AC-energized solenoids. The oldest models of electric razors were powered by hand. Flywheels in the devices were driven by pulling a cord by hand.
