The Wahl 1001 is a size 40 fine replacement blade set for animal trimmers. It is intended for owners replacing the cutting component on compatible Wahl equipment. Match the full blade number and the trimmer's model before fitting a replacement, since a blade's size designation alone does not establish compatibility.

Routine blade care remains important after replacement. Wahl recommends clearing away trapped hair with a brush and keeping the cutting surfaces lubricated with clipper oil. Apply oil before use and replenish it during extended grooming work. After cleaning, re-oil the blade before storing the trimmer.
