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.
Technology has evolved how these products are made. The market today has a huge variety of cheap razor blades to choose from. Straight razors, disposable razors, and electric razors are examples of razors on the market. Each variety was invented at a different time.
Straight razors were the dominant types of razors in use before the advent of the 20th century. Cut-throats is the other name for straight razors. They consist of handled with a single sharpened edge. Carbon steel and stainless steel are the two most commonly used material in making them. Stainless steel blades are durable but hone and strop more slowly. Conversely, carbon steel blade hones and strops faster but does not last long.
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.
Other models of electric razors use rechargeable batteries. Another option besides rechargeable batteries is electro-mechanical oscillators which are driven by AC-energized solenoids. The initial electric razors used to be powered by hand. One had to pull a cord which drove a flywheel.
