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 look like straight razors and are used in the same way. The main difference is that razors are disposed after use. They may be designed to use a single-edged blade or double-edged blade. These varieties do not require honing or stropping. The razors are prone to wearing out fast. The useful life of blades can be prolonged by providing proper care such as cleaning and drying well when not in use.
The design of safety razors allow them to protect the skin from being cut by any part of the blade except the edge. Safety razors were invented by Jean-Jacques Perret in the year 1762. They have similar mechanism of use and appearance as straight razors. The difference is that safety razors have sleeves enclosing the blade. Modern varieties protect the skin by including safety bars. Single-edged and double-edged models are the two types of safety blades.
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.
