The Oster Clipmaster top and bottom blade combo set pairs an 83AU top blade with an 84AU bottom blade. It provides both cutting components together when replacing the blade pair on a compatible Clipmaster setup.

Oster uses carbon steel with heat treatment and its Cryogen-X process before hand-finishing the blade surfaces. The set reference is 078511-126-001. Use the 83AU and 84AU designations to identify the components, and follow the machine instructions for fitting, tensioning and lubrication.
