What the AI looks for in Dog Grooming Clipper Replacement Blades

Blade fit
A5-style detachable blades fit Andis UltraEdge/AG, Oster A5/A6 and Wahl KM clippers. Adjustable trimmer blades for Wahl Bravura/Arco-type models are a separate system. A blade from the wrong system will not latch onto the clipper.
Blade number
Higher numbers cut shorter. A #10 is the all-purpose sanitary and paw blade, #7F to #4F suit body finishes, #30 is mainly used under snap-on combs, and #40 is surgical. Picking the wrong number is the most common reason for a too-short or uneven cut.
Full tooth vs skip tooth
An F suffix means full tooth, for a smooth finish. Skip-tooth blades are for rough cuts and dematting. Skip-tooth blades can nick skin on loose areas, while full-tooth blades leave a cleaner finish.
Cutter material
Ceramic cutters run cooler, and treated steel holds an edge longer. Blade heat and dullness cause clipper burn and pulling.

Brands that matter

  • Andis: UltraEdge steel and CeramicEdge blades.
  • Oster: CryogenX treated steel blades.
  • Wahl: KM-series detachable blades and adjustable trimmer blades.

What to avoid

  • Unbranded 'compatible' blades of unknown steel and tolerances.
  • Using blades without blade oil or coolant.
  • Buying a #40 for routine body clipping.

Questions

Do I need a #30 or #40 to use snap-on combs?

Snap-on combs are usually used over a #10, #30 or #40 blade. Check the comb maker's guidance for which base blade it fits.
