The debate about which clipper blade vs comb attachment is the topic I'd love to talk about today. Some say it's for, some say against the attachment comb, and it seems that the battle will never be decided. Here are some things to keep in mind when choosing from the two options, and then we'll discuss how important one is over the other.
Comb attachments are an easy way to get started clipping without having a range of metal blades because not everyone has access to a variety of clipper blades and the cost can be quite considerable to set yourself up for clipping a range of different coat types, so attachment combs may be your only option.
However there are some points that you need to be aware of and to avoid costly mistakes.
Clipper Blade
Detachable clipper blades are quicker and easier to work with than a comb attachment, especially when working with shorter lengths. It's so much easier to whizz through the coat with a No.5F for example, than having to work your way through the coat with an attachment comb that matches that (6mm or something).
A detachable clipper blade is quick and simple to use, take for instance the Clipit Quattro Cordless Clipper with its pop-on and pop-off blade system. This clipper offers a range of 7 different lengths of blades to keep the pet's coat short, depending on the overall required length. Blade lengths range from 0.25mm (#40 blade) to 13mm (#3F blade), but for longer coat lengths you can place a comb attachment on a No.30 or No.10 clipper blade to provide more versatility.
Helpful tip: The higher the blade number, shorter the cut. Lower the blade number, longer the cut.
A regular size clipper blade has teeth that are spaced just right to guide hair into the cutting area and feed perfectly because of its tooth space. It doesn't jam or skimp unless the coat isn't tall enough, and it stands up well enough for cutting because of the space between its teeth.
Which length Clipper Blades Should I Use?
Choosing the right clipper blade comes down to understanding the coat type, desired finish, and grooming purpose. If you're new to grooming—or upgrading your kit—knowing which blade number does what can take the guesswork out of buying and save you both time and frustration.
🔢 Understanding Clipper Blade Numbers
Clipper blades are numbered based on the length of hair they leave behind. The lower the number, the more hair is left on the coat. The higher the number, the closer the cut to the skin.
For example, a No.3F blade leaves 13mm of coat, while a No.40 blade leaves just 0.25mm, ideal for surgical or sanitary areas.
Each blade is designed for a specific result—from smooth summer clips to fluffy teddy bear finishes. Blade lengths are typically measured in millimetres (mm) or inches, and you can find a full blade chart at the end of this article to guide your choices.
Factors to Consider When Choosing a Blade Length
Breed and coat type: A curly-coated poodle needs a different blade than a double-coated husky.
Time of year: In warmer months, shorter blades like No.7F or No.10 may be used for cooling clips.
Owner preferences: Some clients prefer a close, manageable trim; others want a fuller, fluffier look.
Grooming frequency: For pets that are groomed regularly, longer blade lengths or attachment combs can be ideal.
Most Popular Blade Choices
No.10 (1.5mm) – Standard for sanitary trims, pads, and under ears
No. 7F (3.2mm) – Great for body clips on matted or thick-coated breeds
No. 5F (6.3mm) – Leaves a plush finish ideal for pet trims
No. 4F (9.5mm) – For fluffy teddy bear cuts on bichons, doodles, and shih tzus
No. 3F (13mm) – Leaves the longest coat for a full, soft finish
No.40 (0.25mm) – Used by vets for surgical prep and groomers for paw pads and close clipping under combs
Comb Attachments for Dog Clippers
Comb attachments (also commonly known as blade guards) are affordable and durable, and can be bought individually or as a set of 8. The Wahl Metal Comb Attachment Set of 8, offers you cutting lengths from 3 -25mm and are housed in a clear storage case, colour-coded for at-a-glance identification. However when using comb attachments you may require multiple passes through the coat to achieve the desired cut.
Comb attachments play a part when the owner wants a lot of length on the coat or for setting the length on heads and faces prior to scissoring. The only time you really use a comb attachment is on body hair that you want left longer than 1/2". Anything 1/2" or shorter there is a blade that leaves that length.
When it comes to achieving a consistent coat length with minimal effort, attachment combs can be a real time-saver—especially for pet trims and salon grooms.
Rather than relying solely on scissoring or switching between multiple blade sizes, attachment combs allow you to clip at various lengths quickly and easily, making them perfect for blended finishes or softer, natural looks.
What’s more, Wahl stainless steel attachment combs are fully compatible with the Clipit Quattro Clipper, as long as you're using an A5-style base blade underneath (like a No 30 or No 10). That means you can enjoy the flexibility of clip-on guide combs without compromising on power, speed, or precision.
Whether you’re investing in a full comb attachment set or just need individual length guides, this add-on tool expands what your clipper can do. And since all our comb attachments fit any standard A5 clipper blade, you’re getting maximum versatility and value in one go.
Perfect for:
Puppy grooms
Tidy trims between full grooms
Pet owner maintenance cuts
Blended finishes on legs, faces, and furnishings
However certain breeds do actually look better with an attachment comb, take for instance the 6mm attachment comb (purple), it can be used on curly coats to get a nice finish, however on other coat types it can look a bit shabby! But is does really depend on the coat type.
Prepping the coat to use a Comb Attachment
You have to make sure that the coat is thoroughly brushed, de-matted and combed prior to using comb attachments so if the coat isn't prepped properly then the comb is going to snag on every tiny knot you've accidentally missed and increase time spent on clipping.
That and the fact the comb will constantly pack with hair if you're going through a coat that is going from quite a long length to short. More so if you're feeding too much hair at once through your clipper. In our blog, 6 Things that can Cause Issues with Comb Attachments. we talk about some of the issues using comb attachments on a No.30 clipper blade.
Pushing the blade and attachment comb too hard through the coat. The blade is overloaded with hair, has nowhere to go.
Damp hair. Moisture in the coat, the blade will struggle.
Dry, thick hair. Wide spaced teeth feeding into a surgical cut, will break teeth.
A slow, unserviced clipper, not running at full capacity.
Coats with product build-up will cause issues.
Using a No.30 blade, better using a No.10.

How to take care of your clipper blades and comb attachments.
Every tool needs to be taken care of to ensure its longevity and improve its functionality. The same case goes for dog clipper blades and comb attachments. As a professional groomer, you need to take care of your clipper combs to ensure that they can serve you for long.
Here are some tips on how you can maintain the quality of your clippers:
Clean your blades regularly - Make sure that you wash your blades with blade wash at least once a week. Cleaning the blades will help keep them free from any dirt or debris that might affect their performance during grooming sessions.
Check for wear and tear - Your blades should be maintained every three - six months or so depending on how often you use them during grooming sessions as well as how frequently they get cleaned up properly after each use (more frequent cleaning will Clipit Blade Care Pack will ensure optimal performance). This is especially true if you work with thick-coated dogs like German Shepherds or Huskies because these breeds tend to shed more than other breeds do which
It is important to keep your comb attachments clean, especially after use. You can use warm water and soap or disinfectant wipes to clean them up. It is also advisable to wipe them with a dry cloth after washing them. Do not let them get wet as this could damage them permanently. And finally don't forget to oil the comb attachment spring frequently, this will make it easy to get them off and on the blade.
When to Use a Clipper Blade
Choose a clipper blade when:
You need a close, hygienic, or veterinary-grade trim
The dog has matting or a thick undercoat
You want a polished or competition-level finish
You're grooming large areas like the body or flanks
Blades are your go-to when precision and power are key. They're especially helpful for breeds like spaniels, terriers, and schnauzers where you want a smooth outline.
When to Use an Attachment Comb
Go for attachment combs when:
You're maintaining an already groomed coat
The coat is clean, brushed, and free from matts
You’re doing teddy bear trims or pet-friendly shapes
You need length flexibility without multiple blades
Attachment combs are ideal for fluffier finishes, sensitive dogs, and saving time when a soft look is the goal.
How to Get the Best Results
Always use a clean, sharp blade underneath your comb attachment—preferably a No.30 for the closest contact.
Spray blades and combs with Clipit Ice Care before and during grooming to prevent heat build-up and ensure smooth glide.
For extra precision, finish with scissoring in tricky areas like the face, feet, and tail.
Final Thoughts: Which One Should You Use?
Use clipper blades for precision, close work, and efficiency on dense or matted coats.Use attachment combs for versatility, fluffier finishes, and speed on well-maintained coats.
For many groomers, the real power lies in using both tools together—a solid clipper blade foundation with the flexibility of attachment combs for finishing.
