What Blades Fit the Wahl KM2? (and Other Wahl Models)
If you’ve got a Wahl KM2 clipper, you might be wondering which blades are the perfect match. While the KM2 is officially an A5 model clipper—meaning it should fit all A5-style blades—there are a few limitations you should know about. Let’s break it all down so you can get the best blades for a smooth and stress-free grooming experience.
The Best Blades for the Wahl KM2
To keep your KM2 clipping like a dream, we recommend:
Wahl A5 Blades
A perfect match! These blades are designed specifically for Wahl A5 model clippers, so they snap on effortlessly and run smoothly. Compatible with both Competition Series and Ultimate Competition series, you can read more about the differences here.
[product=wahl-ultimate-competition-series-size-10-blade-1-8mm]
The Wahl Ultimate Competition Series Size 10 blade leaves the coat 1.8 mm.
The black coating on Wahl's Ultimate series blades fills in imperfections in the steel for a faster clip and smoother result with fewer track marks. Speeds up both clipping and finishing time.

Blades That Might Not Work With the Wahl KM2
Laube Blades – Unfortunately, these blades don’t fit the KM2 properly anymore.
AllGroom Blades – Another brand that doesn’t quite click into place with the KM2.
Geib Buttercut Blades – These do fit, but they can be a little tricky to attach and tend to be a bit noisier than other options.
What About Older Wahl Models Like the KMSS and KM1?
If you’ve got a trusty Wahl KMSS or KM1, great news! These older models use the same A5 blade system as the KM2, so Wahl, Andis, and Heiniger A5 blades will work just as well on them.
The Wahl KM10 and KM Inspire – Fully Compatible With ALL A5 Blades!
For those looking for a clipper with ultimate flexibility, the Wahl KM10 and KM Inspire are your best bets. These professional-level clippers work with all A5 blades, including Laube, Geib and AllGroom, so you don’t have to worry about compatibility issues.
How Do I Figure Out Which Blades Are A5?
Luckily enough, we've made it easy! On our website, we've added handy badges to all A5 blades so you can identify them at a glance. Simply look for the A5 badge on the product photo, and don’t forget to read the description for any clipper exclusions. This way, you can shop with confidence knowing you’re getting the right fit for your clipper. If you're ever unsure, feel free to get in touch—we’re always happy to help!
Keep Your Blades Sharp for the Best Results!
Even the best blades won’t perform well if they’re dull. A sharp blade ensures a smooth, effortless cut and prevents pulling or snagging, which can be uncomfortable for your pet. Regular sharpening extends the life of your blades and keeps your clippers working at their best. If your blades are feeling a little blunt, don’t worry—we offer professional sharpening services to bring them back to peak condition! Let us take care of the sharpening so you can focus on flawless grooming.
