Gillette and the trick of giving away the handle to sell the blades

In the early 1900s, shaving was a commitment. You used a straight razor that had to be sharpened regularly, and one slip meant a cut on your face. Then King Camp Gillette showed up with a simple idea: a disposable blade you toss when it wears out. But what really made him rich wasn't the blade itself. It was figuring out how to charge for it.

Cheap handle, expensive blade

Gillette's move boils down to a line every business owner should remember: the goal isn't to sell the device once, it's to sell the refill a thousand times. The razor handle was cheap and durable. The blades wore out fast and had to be bought again and again. That was where the real money lived.

The popular story says Gillette gave the handles away to hook people. The truth was messier: for years he sold them at a fair price. But the principle held anyway. Once the handle is in your bathroom, you're married to its blades. And nobody buys a new handle just to switch blade brands.

Give away the handle and sell the blades: the device is the bait, the refill is the business.

Why it works so well

The model is called "razor and blades," and it works because it changes the moment you make your money. You don't earn it on the first sale; you earn it through the steady drip of repeat purchases. That gives you something incredibly valuable: a customer who comes back on their own, without you having to convince them all over again.

Three things make the trick so powerful:

• The entry barrier is low: the customer steps in almost without thinking because the device is cheap.
• Switching costs money: once you're in, leaving for a competitor means buying the base device again.
• The income is recurring and predictable: instead of one big occasional sale, you get many small, steady ones.

Where you see it today without noticing

Look at your printer. You probably bought it for less than the cost of a dinner out, then discovered that a set of ink cartridges costs nearly as much as the whole machine. That's not a mistake by the company: it's the plan. The machine is the handle, the ink is the blades.

It happens with game consoles, often sold at thin margins or even at a loss, because the money is in the games and subscriptions. It happens with certain pod coffee makers: the device is affordable, but it only works with its own capsules, which you buy for years. And it happens with the original razor, still a huge business a century later.

What your business can learn

You don't need to sell machines to use the logic. The real question is: which of the things you sell gets bought once, and which gets bought over and over? The real value almost always sits in the second kind. A skincare studio can offer a first facial cheap so the client returns every month. A repair shop can keep the first inspection low and live off ongoing maintenance. A dentist can make the first visit accessible and build a relationship from there.

The trap to avoid is the abusive version of the model: refill prices so high the customer feels trapped instead of well cared for. People forgive paying for something they use and value; they don't forgive feeling squeezed. The balance lies in making the repeat purchase comfortable, fair and almost automatic, so coming back to you is the easiest option, not the most expensive one.

Gillette's lesson isn't about razors. It's about understanding that a customer who returns on their own is worth far more than one you have to win back every time. And all of that starts with something as simple as knowing who you've already served and when it's time for them to come back.
