Razor-and-Blades Model

Razor-and-Blades Model (also known as the 'Bait and Hook Model' or 'Tied Products Model') is a clever business strategy where a company sells a primary product (the “razor”) at a very low price, sometimes even at a loss, to lock customers into buying complementary, high-margin consumable products (the “blades”) over the long term. The initial sale is just the hook; the real, recurring profit comes from the repeat purchases of the essential add-ons. The classic example is, of course, King C. Gillette, who pioneered the model by practically giving away his safety razors to sell a lifetime supply of disposable blades. This model transforms a one-time transaction into a continuous stream of recurring revenue, creating a loyal customer base and a formidable economic moat. For investors, identifying a company with a strong and durable razor-and-blades model can be like finding a golden goose that lays a predictable stream of golden eggs. However, not all that glitters is gold, and understanding the nuances of the model is key to avoiding investment traps.

A successful razor-and-blades business is a thing of beauty for a value investor. It often exhibits the qualities that legends like Warren Buffett seek: a durable competitive advantage and predictable future earnings. When analyzing a company using this model, focus on these key characteristics:

• High Switching Costs: How painful is it for a customer to abandon the ecosystem? For a Nespresso user, switching means buying a whole new machine, not just different coffee pods. High switching costs, whether due to financial outlay, convenience, or integration, lock in the customer and protect the “blade” revenue stream.
• Strong Pricing Power: Does the company have the ability to raise the price of its consumables without sending customers fleeing to competitors? This is a direct test of the model's strength. A company that can incrementally increase the price of its “blades” year after year possesses significant pricing power, a hallmark of a great business.
• A Wide and Deep Moat: The model itself is a powerful moat. Competitors might find it easy to replicate the “razor,” but creating a trusted, high-quality “blade” and a distribution network to match is much harder. Look for patents, brand loyalty, and network effects that protect the profitable part of the business.
• A Long Runway for Growth: Is the market for the “razor” saturated, or is there still plenty of room to acquire new customers? A company that is still expanding the installed base of its primary product has a long runway for future “blade” sales and profit growth.

While attractive, this model isn't foolproof. Investors must remain vigilant for potential threats that can dull the sharpest of blades:

• The Generic Competitor: The biggest threat is often a third-party company creating a cheaper, compatible “blade.” Think of generic ink cartridges for printers or non-brand coffee pods. This competition can erode margins and pricing power. The best companies combat this with patents, superior quality, and continuous innovation.
• Technological Disruption: What happens when a new technology makes the entire system obsolete? The rise of digital photography decimated Kodak's film-and-camera (a classic razor-and-blades) business. Always consider if a disruptive technology could eliminate the need for the “blades.”
• Consumer Backlash: Customers are smart. If they feel they are being excessively gouged on the price of consumables, it can lead to brand damage and a search for alternatives. Companies must strike a delicate balance between profitability and perceived fairness.
• Saturation: Once nearly every potential customer owns the “razor,” growth can slow dramatically. Future growth then depends solely on blade sales to the existing customer base, which can be a much slower-growth business.

This century-old model is alive and well, often disguised in modern technology.

• Video Game Consoles: Sony (PlayStation) and Microsoft (Xbox) frequently sell their powerful consoles at a loss. They recoup these losses and make massive profits from selling high-margin video games, online subscription services (like PlayStation Plus and Game Pass, a form of SaaS), and in-game purchases.
• Printers and Ink: The quintessential modern example. Companies like HP and Epson sell home printers for as little as €50, knowing they will make hundreds of euros over the printer's life from proprietary, high-priced ink cartridges.
• Coffee Pod Systems: Keurig Dr Pepper and Nestlé's Nespresso have mastered this model. They sell stylish, convenient coffee makers to get households hooked on their ecosystem of single-use coffee pods, which carry delightfully high profit margins.
• Medical Technology: On the high end, companies like Intuitive Surgical employ this model with surgical robots. They sell the expensive da Vinci Surgical System (the “razor”) to hospitals, which then generates a steady, high-margin revenue stream from the proprietary instruments and accessories (“blades”) that must be used for each procedure.

The Razor-and-Blades model is a powerful engine for creating shareholder value. It generates predictable, high-margin, recurring revenues—music to a value investor's ears. A business with a well-defended razor-and-blades model often has a deep and durable economic moat, allowing it to fend off competitors and generate fantastic returns on capital for years. However, as an investor, your job is to be a skeptic. Don't be mesmerized by the model itself; instead, rigorously test its durability. Ask the tough questions: How strong are the switching costs? Can a competitor make a cheaper “blade”? Is the technology at risk of becoming obsolete? A great razor-and-blades business can be a core holding in a long-term portfolio, but one with a fatal flaw can quickly become a “value trap.” The key is to separate the truly sharp operators from those whose business models are starting to rust.
