Information On Cheap Razor Blades

By Deborah Anderson


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.

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 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.

Safety razors protect the skin from all parts of the tool, except the edge. It was invented by a Frenchman named Jean-Jacques Perret in 1762. The design resembles straight razors only that the blade has wooden sleeves surrounding it. Modern varieties have safety bars included to protect the skin from cuts. Two main types of safety razors exist, that is, double-edged and single-edged.

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.

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.
