Wahl vs Andis vs Oster: servicing differences that matter

Wahl and Andis both use detachable blade systems, but the tensioning mechanisms differ enough that a blade serviced for one rarely sits right on the other.

Oster's rotary motors run hotter under sustained use, which changes how often the internal lubrication actually needs attention versus the blade edge itself.

Whichever brand you're servicing, matching genuine parts to the specific model matters more than most people expect — it's the most common reason a home fix doesn't hold.
