The Wahl #45 non-adjustable blade is a fixed-length replacement for compatible Wahl 5-in-1 animal clippers. Model 41873-7190 leaves approximately 0.5 mm of hair, equivalent to 1/50 inch, for work requiring a very short finish. Wahl classifies this #45 setting as a surgical cut. Its place in the 5-in-1 family describes the clipper system it fits; this particular blade has one cutting length.

The snap-on design allows the blade to be removed for cleaning or exchanged when a different cutting setup is required. Manufacturer compatibility covers Arco, Bravura, Chromado, Figura and Motion, with Wahl support also identifying 5 Style Groom and Creativa in the compatible system. Check the full model number when choosing a replacement to distinguish this #45 blade from other fixed-length options.

Keep hair from building up around the cutting assembly by removing the blade and brushing out loose debris after use. Wahl also recommends frequent blade oiling to reduce friction, support smooth operation and help protect against rust.
