When it comes to clipper blade types, one of the most common questions from both pet owners and professional groomers is: What’s the real difference between FC and ST blades? While they may look similar at a glance, their structure—and more importantly, their function—are quite different.
Let’s break it down clearly so you can make informed decisions when choosing the right blade for your grooming tasks.
🔍 FC vs ST: What Do These Terms Mean?
FC = Finish Cut (or Fine Cut)
FC blades are designed with uniform-length teeth arranged evenly across the blade. This configuration allows for a smooth, polished, and consistent cut, making them ideal for final finishes and sensitive grooming areas. Some brands label these as “F” blades (e.g., 7F = 7FC)—they are functionally the same.
ST = Skip Tooth
ST blades alternate between long and short teeth, which creates wider gaps between some teeth. This design allows thicker or matted hair to feed through more easily, speeding up the bulk cutting process. These blades are perfect for rough pre-clips, blending, or working through dense coats.
🧩 Key Structural Differences: Tooth Design & Cutting Logic
| Feature | Finish Cut (FC) | Skip Tooth (ST) |
|---|
| Tooth Length | All teeth are equal length | Alternating long and short teeth |
| Appearance | Smooth and uniform | Jagged, staggered look |
| Cut Finish | Clean, polished look | Rougher, more textured |
| Feed Rate | Slower, more controlled | Faster, feeds more hair |
| Safety | Safer for beginners and sensitive areas | Requires skill to avoid skin nicks |
This difference in
tooth geometry is what defines the cutting experience. FC blades glide through the coat like a precision tool; ST blades, on the other hand,
"bite" deeper and faster, ideal for tough grooming situations.
⚙️ Blade Size Compatibility: Which Types Come in FC or ST?
Understanding which blade sizes offer FC or ST variations can help you match tools to tasks more effectively.
Sizes #10, #15, #30, #40, #50 → Only available as FC. These are designed for sanitary trims, surgical preps, and tight detail work.
Sizes #3, #4, #5, #7 → Available in both FC and ST. These are your main grooming blades, and choosing between FC or ST depends on whether you're aiming for a finished look or tackling tough fur first.
💡 Tip: If the blade says “F” (e.g. 5F, 7F), it’s a Finish Cut. If it’s unlabeled, check the teeth—it might be an ST.
🐶 Real-World Cutting Results: What You Can Expect
Imagine grooming a Golden Retriever with a thick double coat:
Use a 7ST blade before the bath to quickly remove dense undercoat and reduce drying time.
Then switch to a 7FC blade after the bath to polish the surface, blend layers, and leave a smooth finish.
Each blade plays its role—not better or worse, just purpose-built for different phases of the grooming process.
🛑 Safety Note: FC Blades Are Forgiving, ST Blades Are Not
FC blades are your safest bet when you’re working close to the skin or on sensitive pets. Because of the uniform teeth, they’re less likely to catch skin, especially with wriggly animals.
ST blades, on the other hand, are power tools in the grooming world. They work fast but require steady hands and good technique. If used carelessly, they can nick the skin or leave uneven cuts.
👉 Always hold the skin taut and keep blades cool during use to ensure safety and comfort.
🧠 In Summary: Why the Difference Matters
Choosing between FC and ST blades isn’t just about the finish—it’s about grooming strategy:
Understanding this difference gives you more control over your grooming results—and more confidence in using your tools properly.
