What it is

Two size 40 blades — 0.25 mm (0.01 in) — with a ceramic cutter and a stainless comb, listed for a long series of Andis-type detachable-blade machines.

The right use for a very short blade

Clean-up. Between pads, around a sanitary area, or preparing a spot a vet has asked you to clear. Not a body clip: at this length there is effectively no coat left, and coat is what protects skin from sun, cold and insects.

Why a spare matters

Blades dull unpredictably and heat predictably. A second blade of the same size means a hot or blunt blade is a thirty-second swap rather than the end of the session with a half-clipped dog.

Ceramic, and dropping it

The cutter is ceramic, which runs cooler and chips. Treat a dropped blade as suspect and check the teeth before it touches an animal.

The questions owners ask

Is a size 40 usable on a pet?

For clean-up around pads and for surgical preparation, yes. For a body clip, no — a quarter of a millimeter leaves skin exposed, and the dog then needs protecting from sun and cold. Owners reaching for a "summer cut" want a comb over a 10, not a 40.

Why buy two?

Because a blade dulls or heats halfway through a dog, and a second one turns that into a pause rather than an abandoned session. It is also why professionals keep several of the same size.

Do they fit my Andis?

Cosyonall lists Versa, AGC, AGP, AGRC, AGCL, AGR Plus, AGRV, DBLC, MBG and SMC. Match the model code on your machine rather than the brand name — Andis makes machines with different fittings.

    • Ceramic runs cooler than steel-on-steel, which matters most on the areas this blade is used for
    • Half a millimeter reaches between pads where nothing else will
    • Far too short for a body clip — this is not a general-purpose blade

    Best for: Paw pads and clean-up work, alongside a size 10 rather than instead of it.
