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.
In years before the 20th century, straight razors were the commonest kinds of razors in existence. They are also called cut-throats. They are made of handles, which have one sharpened edge. Two major kinds of materials are used to make them, that is, carbon steel and stainless steel. Stainless steel strops and hones slowly and holds edges longer. On the contrary, carbon steel have less durable edges and they strop and hone faster.
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 resemble straight razors in appearance and use. However, the blade they use is disposable. The blade may be single-edged or double-edged blades which are cut into half. There is no need for stropping and honing in these varieties. Razors wear out faster, but useful life of the blade can be lengthened through goo care. Part of good care involves drying well after 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 are also referred to as electric dry shavers. These models incorporate an oscillating or rotating blade. These devices operate on small DC motors that are powered by either mains electricity or batteries. There is no need for using water, soap, or shaving cream when using these kinds of razors.
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.
