Razors refer to bladed tools used for shaving the body. Archeological evidence reveals that razors have been part of the human society long before the Bronze Age. People in the ancient worlds used bronze and obsidian to make their razors. Historical razors were oval in shape and had one shorter end that contained a tang. It was not until the 18th century that razors in use currently were invented. The 1960s led to the invention of the electric models.
Technological advancements have led to a lot of evolution in these products. Today, there are many different kinds of cheap razor blades on the market. Some major examples include disposable razors, electric razors, and straight razors. All the types of razors were invented at different times in history and have evolved differently to 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 carbon steel and stainless steel blades are in production by various companies, but stainless steel blades are much harder to come across. The razor rotates between two protective scales on a pin. The scales protect the user from injury and the blade from damage when it is folded. Handle scale may be made from celluloid, mother-of-pearl, wood, plastic, or bone. Ivory was in use some times back, but its use has been discontinued.
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.
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 dry shaver is the other name for electric razors. They have a blade that rotates when they are working. DC motors are the main sources of power. The DC motors derive power from mains electricity or rechargeable or maintenance free batteries. Electric razors are more convenient because one does not need water, shaving cream, or soap to use them.
There new models of electric razors that have come up, which use rechargeable batteries. An alternative to rechargeable batteries is an electro-mechanical oscillator that is driven by AC-energized solenoid. The earliest models were powered by hand. This involved someone pulling a cord that drove a flywheel.
