Information On Cheap Razor Blades

By Deborah Anderson


A razor refers to a bladed tool primarily used to remove undesirable hair on the body, shaving. Razors existed in many cultures in the ancient world before the Bronze Age. In Bronze cultures, this tool was made using obsidian or bronze. They were had an oval shape, with the short end having a small tang protruding. The modern razors were invented in the 18th century and the 1960s saw the invention of the electric razors.

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.

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 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.
