Gillette's disposable blade (1904): the original razor-and-blades business model

Around 1900 American men either struggled with stropping and honing a straight razor or paid a barber for every shave. Gillette, a traveling salesman for Crown Cork and Seal, kept hearing from his employer William Painter — inventor of the disposable bottle cap — that the real money is in a product "which once used, is thrown away, and the customer keeps coming back for more."

Split shaving in two: a razor you buy once and a blade so cheap to make it can be thrown away dull — the profit moves from the one-time sale to the refills.

Gillette sketched a disposable-blade safety razor in 1895; it took MIT-trained engineer William Emery Nickerson six years to work out how to mass-produce thin stamped steel blades. The American Safety Razor Company was founded in 1901, the patent was granted November 15, 1904, and the company was renamed Gillette Safety Razor Company. In its first year it sold 51 razors and 168 blades; the next year, 90,884 razors and 123,648 blades.

The 'razor and blades' model became eponymous. Gillette seeded a generation of customers by selling razor sets to the U.S. military in World War I — 3.5 million razors bought in 1918 alone — and veterans came home already holding the disposable-blade habit. Printers' ink, coffee pods and game consoles would all later run on the same logic: the durable is the door, the consumable is the business.

King C. Gillette was a traveling salesman hawking bottle caps when his boss, William Painter, handed him the brief that shaped his career: invent a disposable product people use once and keep buying. In 1895, standing at the basin one morning, Gillette realized the answer was in his hand — a razor whose blade could be replaced instead of resharpened.

Turning the idea into steel took six years and one crucial hire: William Emery Nickerson, an MIT-trained engineer who built the machinery to grind thin sheet-steel blades at scale. The American Safety Razor Company — renamed Gillette Safety Razor Company in 1904 — received its patent on November 15, 1904. The economics flipped the product inside out: as Gillette himself put it, the blade was 'so cheap to manufacture that its cost to the consumer would permit of its being discarded when dull.' The first year sold 51 razors; the second, 90,884.

Gillette then industrialized the habit. He put professional athletes in his advertising and made sure American soldiers went to World War I with government-bought Gillette sets — 3.5 million razors in 1918 — and returned home as lifetime blade customers. The durable razor was the entry ticket; the discardable blade was the business, and the model now carries the brand's name.

The creative move was redefining the product: the razor became a holder, and the blade became the sale that repeats for as long as the customer shaves.

A dull blade had been a maintenance problem — stropping, honing, barber visits — and disposability converted that chore into a purchase.

The military order turned 3.5 million soldiers into trained users at the government's expense, converting a product into a default habit overnight.

Every later razor-and-blades business — ink, pods, consoles, razors by subscription — is running the loop Gillette closed in 1904.

Price the durable as the door and own the refill: recurring consumable revenue beats one-time sales, and a habit handed to customers early pays off for decades.

Imitators flooded in, but the head start held: by 1905 Gillette had a London sales office and a Paris blade plant, and by 1906 a Canadian plant and European distribution. When the original patent expired in 1921, the company relaunched the classic razor at a dollar. Gillette stayed the blade category's defining brand into the cartridge era, and Procter & Gamble bought it in 2005, creating the world's largest personal-care business. Its descendants run from printer ink to coffee pods to game consoles — every business whose real product is the refill.
