You’re staring at your dog’s paws, or maybe a horse’s fetlock, and your standard clipper just feels like a blunt instrument trying to do surgery. It’s clunky. It’s loud. It’s not getting into those tiny crevices between the pads without a struggle. This is usually when people find out about the wahl 5 in 1 clipper blades system.
Honestly, it’s a bit of a weird piece of tech. Instead of having a drawer full of different metal chunks—a #10 for the body, a #30 for the pads, a #40 for a surgical prep—you just have one blade with a little plastic lever on the back. You flick it, the teeth move, and suddenly you’ve changed the length of the cut.
It’s genius. It’s also incredibly frustrating if you don’t know how to baby them.
What are Wahl 5 in 1 clipper blades anyway?
Most clipper blades are static. You pop on a #10 blade, and it cuts at 1.5mm (roughly 1/16 of an inch) until you take it off. The wahl 5 in 1 clipper blades are different because they are adjustable. By sliding a lever on the bottom of the blade assembly, you can cycle through five specific industry-standard lengths:
- #9 (2mm)
- #10 (1.8mm)
- #15 (1.5mm)
- #30 (0.8mm)
- #40 (0.6mm)
Basically, it's like having five different blades in your hand at once. This is the primary reason why groomers use them for "finish work"—the delicate stuff like faces, ears, and sanitary trims. They fit specific cordless Wahl models like the Arco, Bravura, Chromado, Creativa, and Figura. If you’re trying to snap one of these onto a heavy-duty corded Andis or a Wahl KM10, stop. It won't work. These are designed for the "5-in-1" ecosystem specifically.

The Fine vs. Coarse Debate
Most people just buy the "Fine" blade because it’s the standard replacement. It’s great for silky hair or tight detail work. But if you’re trying to push through a thick Doodle coat or a horse’s winter fuzz, you’ll probably find the Fine blade snagging.
Wahl also makes a Coarse 5-in-1 blade.
The teeth are spaced differently to feed hair faster. If you’ve ever felt like your clippers were "chewing" the hair instead of cutting it, you probably need the coarse version. There’s also a Diamond Blade which has a carbon coating. It’s supposed to stay cooler and last longer. Does it? Some groomers swear by it; others think it’s just a shiny marketing gimmick. In my experience, it does resist rust better if you’re a bit lazy with the oiling.
Why these blades "die" so fast (and how to stop it)
One of the biggest complaints you’ll see in grooming forums is: "I used it twice and it's dull."

Here is the truth. Wahl 5 in 1 clipper blades are more delicate than the heavy steel blades used on corded clippers. Because they have moving plastic parts and a tension spring inside, they don't handle dirt well.
If you clip a dirty dog, tiny grains of sand get between the two metal plates. Because the motor on these cordless units is high-speed but lower torque than a big A5 clipper, that grit creates friction fast. Friction equals heat. Heat equals a dull blade.
The Maintenance Routine (Non-Negotiable)
- Brush first: Use that tiny little brush they give you. Get the hair out from between the teeth after every use.
- The 5-Point Oiling: Put a drop of oil on each corner of the teeth, one in the middle, and one on each side of the "rails" where the blade slides.
- Cooling: If the blade feels hot to the touch, stop. Use a cooling spray like Wahl Blade Ice. If you keep going, you’ll not only burn the pet, but you’ll also warp the tension spring.
Can you actually sharpen them?
This is a controversial topic in the grooming world. Traditionally, many sharpeners refused to touch 5-in-1 blades. They’d say they were "disposable."
That’s not entirely true anymore. Some specialized sharpeners have the jigs to take them apart and grind them. However, it’s tricky. If the plastic tab on the back is worn or the internal spring is shot, sharpening the metal won't help.
✨ Don't miss: Finding the most affordable way to live when everything feels too expensive
Most pros treat them as semi-disposable. You use them for 3-6 months, and when they start pulling, you buy a new one. It's an expensive habit at $30-$40 a pop, but the time you save not swapping blades usually pays for it.
Common Failures: When the lever gets stuck
Sometimes you'll go to switch from a #10 to a #30 and the lever just... won't move. Or it moves, but the blade doesn't.
Usually, this is just packed hair. Hair gets inside the housing and acts like a wedge. You can actually pop the top "cutter" blade off—carefully—to clean the inside. Just be warned: there is a small spring in there. If that spring flies across the room, you are never finding it, and your blade is officially a paperweight.
Moving Forward with Your Grooming Setup
If you’re just starting out, don't try to do a full-body shave on a matted dog with a wahl 5 in 1 clipper blades setup. You’ll kill the blade in ten minutes. Use these for the "pretty" work.
Next steps for better blade life:
- Check your model: Make sure you actually have a Bravura, Arco, or similar model before buying.
- Wash the pet first: Never, ever clip a dirty coat with these blades if you want them to last more than a week.
- Get a backup: Always keep a spare blade in your kit. These things have a habit of failing right when you're halfway through a face trim.
- Invest in a "Blade Ice" spray: It cleans and cools simultaneously, which is a lifesaver for the delicate tension springs in these units.
