Straight razor

technology Maturity 11-13 Next article →

A straight razor is a manual tool designed for shaving hair.

These tools are also known as open razors or cut-throat razors. The defining feature of a straight razor is a blade that can fold into its handle. This handle is not actually a handle in the traditional sense. It consists of two protective pieces called scales. These scales protect the delicate cutting edge from damage when the tool is not in use. They also serve as a safety feature to prevent accidental cuts.

To understand the mechanism of a straight razor, one must look at its specific anatomy. The blade rotates on a pin known as the pivot. The narrow metal end of the blade that extends beyond this pivot is called the tang. The tang acts as a lever to help the user raise the blade from the scales. A user can also rest fingers on the tang to stabilize the razor during a shave.

The top, non-cutting side of the blade is the spine. The sharp side opposite the spine is the cutting edge. The curved lower part of the blade between the shank and the edge is the shoulder. The point where the shoulder meets the edge is the heel. The tip of the cutting edge is called the toe.

Straight razors vary significantly in their design and construction. The blade's performance depends on its grind, which refers to how the metal is shaped. Grinds range from a thick "true wedge" to various levels of hollow grinding.

A hollow grind means the blade is curved inward. As the grind becomes more hollow, the blade becomes more flexible and the edge more delicate. This allows for a closer shave but requires much more skill to use and sharpen. Blades are also categorized by their point shape. Common shapes include the round or Dutch point, the French point, and the American or square point.

Some specialized versions include the Spanish point or the Spike point.

Humans have used various tools for shaving throughout history. In prehistoric times, people used sharpened flint, shark's teeth, or clam shells.

Ancient Egyptian tombs have revealed razors made of solid gold and copper from the 4th millennium BC. During the New Kingdom, craftsmen produced bronze razors with fixed handles. In the 6th century BC, the legendary king Lucius Tarquinius Priscus reportedly introduced the razor to ancient Rome. The modern era of the straight razor began in Sheffield, England. In 1680, manufacturers there produced the first steel-edged folding razors. These "Sheffield wares" were exported as far as the Gulf of Finland, roughly 1,200 miles from their origin.

Technological advancements changed how these blades were manufactured. By 1740, Benjamin Huntsman began producing razors with hollow-ground blades made from cast steel. He achieved this using a specialized steel-making process that he invented. Although the French adopted his process, they were initially reluctant due to nationalist sentiments. English manufacturers were even more hesitant and only adopted Huntsman's method after seeing its success in France.

These steel-edged razors became the primary method of manual shaving for over two hundred years. They remained in common use until the mid-20th century.

The market for straight razors changed with the invention of new technologies. In the late 19th century, King C. Gillette introduced the double-edged safety razor. Unlike the straight razor, the safety razor used replaceable blades that were meant to be discarded after one use. This required a much smaller initial investment for the user. As shaving became less intimidating and more people began to shave themselves, the demand for professional barbers also decreased. Electric razors further reduced the market share for straight razors, particularly after the 1950s. However, a 1979 study by Dutch researchers found that straight razors shave hair approximately 0.002 inches shorter than electric razors.

Interestingly, the popularity of the straight razor has seen a recent resurgence. Since 2012, following its appearance in the James Bond film *Skyfall*, global sales have increased. Many users now view the straight razor as a more sustainable and efficient product. For example, the German company Dovo reported a massive shift in demand. In 2006, their production was below 8,000 units per year. By recent years, they have been selling 3,000 units per month. This surge has also revitalized associated trades, such as bladesmiths and leather craftsmen. Today, manufacturers continue to produce these tools across Europe, Asia, and North America.
