Before the plastic razors we know today, people used a safety razor (metal razor). Until the 17th century, straight razors were used so people had to be shaved by experienced barbers. Then the safety razor came along, and it got much easier for people to do their own shaving. It really started to gain mass popularity in the 20th century, when it became possible to change its double-edged blade.
What are the benefits of a metal razor?
One blade for greater results
Single-use plastic products’ introduction into the market led to them invading our homes and, especially, our bathrooms. The competition sparked between the leading razor manufacturers, who started differentiating their products by adding more and more blades.
However, more blades does not necessarily mean a better shave. Skin irritations and cuts are caused by the blades passing over the skin, which worsens with the number of blades. Therefore, single-blade razors are less harmful to the skin and reduce the risk of pain after shaving.
Moreover, replacement razor heads with multiple blades are often much more expensive than double-edged blades. As a result, people tend to use them too long, even when they are dull. This is a bad habit because dull blades are prone to irritate the skin and create ingrown hairs and shaving bumps. Since single blades are much cheaper, they help you take care of your skin because you can change them as soon as they start to wear out.
