Professional dog clipper blades

A clipper blade determines the length your dog's coat is left at, and having the right one on hand matters more than the clipper itself once you've already invested in a machine. Blades are sized by number, wear out with use, and generally need replacing or sharpening well before the clipper motor does.

Choosing a blade size

Blade numbers correspond to the length of coat left behind, with lower numbers leaving hair longer and higher numbers cutting closer to the skin. Coat type matters as much as the number — a blade that glides through a soft, single coat can drag and heat up faster on a thick double coat, which is worth knowing before you start on a breed you haven't clipped before.

Compatibility matters too: not every blade fits every clipper, so check the fitting against your specific machine rather than assuming a universal fit, particularly if you're buying a spare or replacement rather than the blade that came with the clipper.

Looking after a blade

A blade that's dragging, snagging or heating up quickly is usually blunt rather than faulty, and clipper oil applied before and during use makes a genuine difference to how long it stays sharp. Cleaning hair out of the blade teeth after every use, rather than leaving it packed in, extends how long it lasts between sharpens.

Keep a spare on hand if you clip regularly — a blunt or overheated blade partway through a groom is uncomfortable for your dog and a poor result for you, and swapping to a fresh one is far quicker than stopping to clean and oil mid-session.

Common questions

What do the numbers on clipper blades mean?
The number refers to how much coat length the blade leaves behind, with lower numbers cutting less close and higher numbers taking the coat down closer to the skin. There's no single number that suits every dog — it depends on coat type, breed and the look you're going for.
How do I know if a blade needs replacing?
A blade that drags, pulls at the coat, heats up quickly or leaves an uneven finish despite being oiled and cleaned is usually past its best. Sharpening can extend a blade's life for a while, but eventually the teeth wear down enough that replacement is the only real fix.
Do I need to oil a clipper blade every time I use it?
Yes, ideally — a drop of clipper oil before you start and again partway through a longer groom keeps the blade running cooler and cutting more cleanly. Skipping oil is one of the quickest ways to blunt a blade well before its time.
