Who invented the first double-edged disposable safety razor and founded the company that still bears his name?

King C. Gillette is the answer. The American inventor and businessman developed a shaving system built around thin disposable blades, a double-edged safety razor, William Emery Nickerson’s manufacturing work, and the Gillette Safety Razor Company, which helped move everyday shaving away from straight razors that needed regular sharpening.

King C. Gillette’s Razor Idea

King C. Gillette’s key idea was a safety razor that used thin, replaceable blades. The concept addressed a common shaving problem: straight razors required sharpening, stropping, and careful maintenance. Gillette’s design gave customers a way to shave with a handle they could keep while replacing the blade when it became dull.

The Double-Edged Safety Razor

The Gillette razor used a double-edged blade held inside a safety razor handle. That design exposed the cutting edges while giving the user more protection than a traditional straight razor. The double-edged format also made the blade useful from both sides, which became part of the product’s practical appeal.

Turning the Blade Into a Manufactured Product

William Emery Nickerson played an important role in making Gillette’s idea workable as a manufactured product. Producing very thin steel blades that were sharp, consistent, and inexpensive enough to replace created technical problems that had to be solved before the razor could succeed. Nickerson’s manufacturing work helped turn the disposable blade concept from an idea into a practical shaving product.

The Company Built Around Replaceable Blades

Gillette founded the Gillette Safety Razor Company, which became strongly associated with his name and shaving products. The business model depended on selling a durable razor handle along with replaceable disposable blades. That blade-replacement system became one of the most important parts of Gillette’s success because customers did not need to buy a new handle every time the cutting edge wore out.
