The Oster size 1A detachable blade is a replacement cutting blade for Classic 76, Octane, Model One, Model 10 and Outlaw clippers. The size marking identifies the required blade within this range, making it straightforward to select a matching replacement or add another cutting option to a barbering kit.

It is made from high-carbon steel with a hardening and cryogenic treatment process. The cutting surfaces are then sharpened and finished.

Choose the exact size 1A for your intended haircut and clipper setup. Oster recommends removing hair and applying blade lubricant after use to maintain the blade’s working surfaces.
