The Oster 76 Size 00000 is a detachable clipper blade for barbers and stylists who need a very close finish. Its nominal 1/125-inch / 0.2 mm cut makes it a short-cutting option for head and facial clipping. The five-zero size designation helps distinguish it from other closely numbered blades when selecting the length for a service.

Oster makes this blade from high-carbon steel in the United States. The manufacturing process hardens the steel to 62–66 on the Rockwell C scale, followed by cryogenic treatment. The cutting surfaces are then sharpened and finished, giving the blade the hardened cutting edges used throughout Oster's professional detachable range.

It fits the Oster Classic 76, Octane, Model One, Model 10 and Outlaw clippers. The detachable format allows the cutting assembly to be removed when changing sizes or performing routine blade care. After each use, clear away cut hair and apply blade lubricant as Oster directs.
