Guest post history of the shaving razor – the truth about knives electricity test physics


Several times a day I get requests to post guest content from unusual sources. Usually it is some niche blog that discovers something I wrote in passing, like mention of my garden or training a hunting Lab. I really don’t need to fill space with entire posts dedicated to organic gardening, just because I use my knives to make homemade salsa. Sometimes, I am not even sure if he requests are coming from real people and not bots. I was about to discard a request from, when I had a idea – Maybe he could write something on the history of the shaving razor, which would be very much on point for the blog.

Historians, studying cave art, speculate that the practice of shaving has existed since prehistory, when early man used seashells, sharpened bone or cracked flint to accomplish the task. Using carbon dating, scientists have discovered that the appearance of these tools corresponds with a reduction in the presence of pre-historic lice in the hair of human remains. The practice of shaving was most likely a response to insect infestation!

The first refined shaving implements appeared in the Bronze Age as humans discovered the magic of metallurgy. Razors of this era have been found with various designs. Some examples are long and flat like a primitive Bowie knife; others are crescent shaped or simple oval disks. Bronze Age razors have been found in Egypt dating to 2000 B.C. and earlier. In this period, the cultural practice of shaping body hair began its long association with personal style as a form of expression. Razors had become invaluable status objects, and those owned by society elites were elaborately designed and decorated.

The greatest advocates of shaving technology were often military in nature. Since disease is so often a companion to war, there is little doubt as to why. History suggests that Alexander the Great encouraged the practice of shaving among his troops so that their beards couldn’t be used against them in hand to hand combat, but avoiding disease and lice, the motivating survival concern of early man, was a likely factor as well.

Although razors would adopt advances in metallurgy, they would take the same basic form until advancements in England in the late 18th century produced the first examples of the modern straight razor with hollow ground blades. These blades, utilizing Sheffield silver steel, were legendary for their brilliant polish and high quality steel.

Even with these advancements, shaving had yet to become a daily practice. Because of the high cost of materials and the steep learning curve in the use of razors of that era, shaving regularly was still relegated to the wealthy who could afford regular trips to a barbershop or to be shaven by servants.

The first example of a safety razor, a straight razor with a protective sleeve that held the blade at the proper angle, was invented in 1762 by a Frenchman named Jean-Jacques Perret. The Kampfe Brothers, German immigrants to the United States, developed and successfully marketed an innovative design in the late 19th century featuring a shortened blade attached to a handle in a wedge shape. These razors still had a fixed blade, and it wasn’t until King Camp Gillette invented the safety razor with a removable blade in 1895 that shaving razors had the chance to hit the main stream market.

Gillette had obtained a contract to supply U.S. troops with his removable double-edged safely blades during World War I. After the war, the returning veterans kept their razors and brought home the practice of shaving regularly. There was a significant demand for disposable razor blades for the first time. Gillette seized this opportunity to dominate that growing industry for half a century.

New technologies created new opportunities for creative entrepreneurs. Although the first patent for an electric razor was filed in 1898 by John O’Rourke, it wasn’t until Jacob Schick, an army Colonel and veteran of World War I, patented his electric razor in 1930 that Gillette’s disposable razors saw their first real competition. Schick’s dry shave electric razors would briefly dominate the market, selling millions of the devices, and electric shavers would enjoy widespread popularity until the 1960s.

In 1960 Gillette launched an innovation that radically change the market once again: the introduction of stainless steel blades. With longer lasting blades, disposable razors became more convenient than their electric counterparts. Although electric razors are still popular today, the introduction of stainless steel blades would insure the continued success of disposable razors into the present day.

Today, the razor complex and diverse. With a resurgence in the use of classic shaving technologies and many consumers looking to reduce the waste associated with disposable blades, straight razors are enjoying a moment of renewed popularity. Single-bladed double-edged safety razors, which use razors that are often cheaper than multi- blade disposable options, are in common production as well. Innovations in disposable blades continue, with brands offering three, four, or five bladed models. As a technology that has existed since the dawn of human culture, one thing is certain: Shaving razors will continue to evolve to meet the demands of the changing marketplace, and new innovations are always around the corner.

Well, like you, I was researching straight edged razors because I was fed up with paying too much money for replacement cartridges for my Mach3 (and getting a sub-par shave in the process) and stumbled across a few useful sites, but nothing that really looked to me like what I am trying to do here. There were a few vendor-type sites and a few informative articles to whet my appetite.
