The Razor and Blade Model Only Works If You Control the Blades
Sell the device cheaply and profit on the consumables. The strategy is famous, frequently attempted, and fails whenever somebody else can make the refills.
The Structure
The model splits a product into a durable component sold at or below cost and a consumable component sold at high margin. The customer commits once and pays repeatedly.
The commercial logic is sound. It lowers the barrier to adoption, converts a one time purchase into a recurring revenue stream, and lets pricing follow usage, so heavy users pay more.
Classic implementations include printers and cartridges, coffee machines and pods, and game consoles sold below cost against software royalties.
The Condition That Makes It Work
All of it depends on one thing: the customer must be unable to buy the consumable elsewhere.
Without that, the model inverts into a disaster. The company has sold hardware below cost to a customer who then buys refills from a competitor. Each unit sold becomes a subsidy handed to whoever supplies the consumable.
Razor and blade is not a pricing strategy. It is a lock in strategy with a pricing consequence, and when the lock in fails there is nothing left.
The Mechanisms of Lock In
| Mechanism | Durability |
|---|---|
| Patents on the consumable | Strong until expiry, then gone |
| Physical or digital authentication | Effective, invites circumvention and litigation |
| Contractual exclusivity | Strong in business channels |
| Certification and warranty terms | Moderate, pressured by regulators |
| Brand and perceived quality | Weakest legally, most durable in practice |
Patent expiry is the predictable failure point. The coffee pod category demonstrated it clearly: while the format was protected, margins were excellent. Once protection lapsed, compatible pods appeared from many suppliers at lower prices, and the economics of the installed base changed permanently.
Authentication chips that reject third party consumables work technically and create legal and reputational exposure. Courts in several jurisdictions have limited how far a manufacturer can restrict what a customer does with a product they own, and right to repair legislation has moved further in that direction.
The Console Version
Games consoles run the purest form. Hardware is frequently sold below manufacturing cost, and the return comes from royalties on every game sold for the platform, plus subscriptions and store fees.
The lock in here is not a physical consumable but a licensing regime: publishing on the platform requires a licence and a royalty. That is considerably more durable than a patent on a cartridge, because it is contractual and applies to a product the platform holder does not manufacture.
The vulnerability is different. If games move to distribution channels the platform does not control, the royalty stream weakens regardless of how many consoles were sold.
The Modern Version
Software and services have adopted the same shape without the hardware. Free or cheap entry, with revenue from usage, storage, transactions, or seats.
The lock in mechanism is switching cost rather than physical compatibility: accumulated data, trained users, integrations with other systems. That form is more durable than a patent because it strengthens over time rather than expiring, and it grows as the customer uses the product more.
The regulatory pressure has moved accordingly, toward data portability and interoperability requirements, which attack exactly this form of lock in.
When Not to Attempt It
The model is a poor choice where the consumable is easy to manufacture, where customers are sophisticated and will calculate total cost of ownership, and where regulators are attentive to aftermarket restrictions.
It is also poor where the durable good lasts a long time, since the company carries the subsidy for years while competitors supply the profitable part. Selling below cost is a bet on a future revenue stream, and any bet requires that the stream is actually protected.
The Bottom Line
Razor and blade pricing subsidises adoption and recovers margin on consumables, which only works while the consumable is genuinely controlled. Patents expire, authentication invites litigation, and regulators increasingly favour the customer. The durable modern version replaces physical lock in with accumulated data and integrations, which is why that is precisely what current regulation targets.
